Series Overview
ComPacT NSX Accessories - Outline
Fixed Circuit Breakers
Fixed circuit breakers can be connected directly to busbars or via cable lugs. Bare cable connectors are also available for bare copper or aluminum cables.
ComPacT NSX circuit breakers can be installed horizontally or vertically, flush or top-mounted, without affecting performance. There are three mounting methods:
● Fixed
● Plug-in
● Withdrawable
The latter two methods require adding corresponding accessories (bases, side plates, etc.) to the fixed version. Many connection accessories are common to all three methods.
Plug-in Circuit Breakers
● Using plug-in circuit breakers allows:
● Withdrawing or quickly replacing the circuit breaker without touching the incoming/outgoing wiring or the mounting base.
● Pre-installing plug-in bases for easy future addition of circuit breakers.
● Isolating the power circuit when the base is flush-mounted or panel-mounted. Comprehensive insulation is achieved using short terminal shields (mandatory) on the device. Protection ratings are:
● Breaker plugged in = IP4X
● Breaker withdrawn = IP2X
● Breaker withdrawn, base with shutters = IP4X
● Plug-in Circuit Breaker Configuration
● Plug-in configuration is achieved by adding a "plug-in kit" to a fixed circuit breaker. To avoid connecting or disconnecting under load, a safety trip device automatically trips the breaker if it is in the ON state before insertion or withdrawal from the base. This safety trip device is included in the plug-in kit and must be installed on the breaker.
● Accessories
● Optional insulation accessories:
● Terminal shields to prevent direct contact with terminals.
● Phase barriers to enhance insulation between phases.
Withdrawable Circuit Breakers
● Withdrawable circuit breakers offer all the advantages of plug-in types and are very easy to operate. They have three positions:
● Connected position: Power circuit connected.
● Withdrawn position: Power circuit disconnected; the breaker can be operated to check auxiliary circuits.
● Breaker removed: The breaker can be taken off the base.
● Withdrawable Circuit Breaker Configuration
● In withdrawable configuration, two side plates need to be installed on both the base and the circuit breaker. Similar to plug-in configuration, a safety trip device automatically trips the breaker if it is in the ON state during insertion or withdrawal, ensuring operation in the "OFF" position.
● Accessories
● The base used is the same as for plug-in. Additionally:
● Rack auxiliary contacts indicate the breaker's "Connected" and "Withdrawn" positions.
● Locking with 1 to 3 padlocks (diameter 5 to 8mm) enables:
● Preventing breaker insertion.
● Locking the breaker in the "Connected" or "Withdrawn" position.
● A toggle switch cover ensures a suitable protection rating regardless of the breaker's position.
● A telescopic shaft for extending the rotary handle allows the door to be closed when the equipment is in the "Connected" or "Withdrawn" position.
Wiring for Fixed Circuit Breakers
Front Wiring
Busbars or cables with lugs.
Standard Terminals
ComPacT NSX100-630 terminals include nuts and screws:
● ComPacT NSX100: M6 nuts and screws.
● ComPacT NSX160/250: M8 nuts and screws.
● ComPacT NSX400/630: M10 nuts and screws.
● These terminals can be used for:
● Direct connection of insulated busbars or cables with lugs.
● Terminal extensions providing more wiring options.
● Phase barriers or terminal shields are recommended. Certain connection accessories require these components (phase barriers are provided in such cases).
● Busbars
● If non-insulated busbars are used for connection, full type testing of the switchboard is required to confirm the configuration.
● Lugs
● Lugs are available for both aluminum and copper cables. Lugs must comply with connection regulations. They must be used with phase barriers or long terminal shields.
● Terminal Extenders
● Terminal extenders connect to the standard terminals of the breaker, providing multiple wiring schemes in a compact space:
● Straight terminal extender
● Right-angle terminal extender
● Corner terminal extender
● Double U-type terminal extender
● 45° angle terminal extender
● Pole Spacing Extenders
● Pole spacing can be increased using pole spacing extenders:
● NSX100/160/250: Pole spacing increases from 35mm to 45mm.
● NSX400/630: Pole spacing increases from 45mm to 52mm or 70mm.
● Busbars, lugs, or terminal extenders can be connected to the line or load side of the breaker.
● Integrated Extenders for NSX100/160/250
● Integrated extenders enable:
● Increasing the 35mm pole spacing of NSX100/160/250 breaker terminals to match the 45mm spacing of NSX400/630.
● Using all connection and insulation accessories available for the next larger frame size (lugs, cable connectors, terminal extenders, terminal shields, phase barriers).
● Compatibility with Interpact INS disconnectors.
● ComPacT NSX devices with integrated extenders can be installed:
● At the rear of the switchboard.
● On a panel using spacers.
● Integrated extenders also:
● Align breakers of different frame sizes within a switchboard.
● Allow the use of identical mounting bases regardless of current rating.
Wiring for Fixed Circuit Breakers - Bare Cables
Bare copper and aluminum cables (without lugs) can be connected using bare cable connectors.
● Single Cable Connectors for ComPacT NSX100/160/250
● Connectors clip onto the breaker terminals or are secured via fixtures onto straight terminal extenders, right-angle terminal extenders, or pole spacing extenders.
● Single Cable Connectors for ComPacT NSX400/630
● Connectors are screwed onto the breaker terminals.
● Double Cable Connectors for ComPacT NSX100/160/250 & 400/630
● Connectors are screwed onto breaker terminals or right-angle terminal extenders, etc.
Rear Connection Terminals
● Breakers mounted on backplates can be wired behind the mounting panel using rear connection terminals.
● Busbars or Cable Lugs
● Rear connection terminals for busbars or cables with lugs come in two lengths. They offer four connection positions.
● Rear connection terminals easily secure onto the breaker's connection terminals. All combinations of rear connection lengths and positions are achievable.
● Bare Cables
● For rear connection with bare cables, single cable connectors for ComPacT NSX100/160/250 can be securely fixed to the rear connection terminal using a clamp.
Wiring for Withdrawable and Plug-in Circuit Breakers
Busbars or Cables with Lugs
● Plug-in bases feature connection terminals usable for front or rear wiring.
● For rear wiring with plug-in bases mounted on panels, the terminals must be replaced with long right-angle terminal extenders.
● For ComPacT NSX630, 52.5mm or 70mm pole spacing extenders are typically required for connection.
● Connection Accessories
● All accessories for fixed breakers (busbars, connectors, terminal extenders, pole spacing extenders) can be used with plug-in bases.
● Bare Cables
● All terminals can be equipped with bare cable connectors.
● Adapters for Plug-in Bases
● An adapter is a plastic component used for 100/160/250 and 400/630 plug-in bases, enabling the use of all wiring accessories designed for fixed breakers (e.g., phase barriers and long/short terminal shields require this adapter).
Insulation of Live Parts
Terminal shields for fixed and plug-in/withdrawable breakers are identical and suitable for all applications up to 690V. Rated for current ranges 100/160/250A and 400/630A, available in long and short versions.
● Terminal Shields
● Terminal shields are insulating accessories preventing direct contact with the power circuit. They meet IP40 protection and IK07 mechanical impact protection.

● Long terminal shields consist of two parts assembled with screws, achieving IP40 protection.
● The upper part has sliding shutters with separation markings for precise cable or insulated busbar matching.
● The rear part completely encloses the connection area. Locally removable fingers allow adaptation for various lugged cables or copper busbar connections.
● Long terminal shields can be installed on the line or load side of:
● Fixed breakers.
● Bases of plug-in and withdrawable breakers. This, combined with the mandatory short terminal shield on the breaker, provides enhanced insulation.
● Integrated extenders for NSX100/160/250.
