Series Overview
Series Overview
Overview
Product Features Overview
- Products of various specifications are all provided with box - type terminals.
- Can connect to circular conductors and flat conductors.
- Can perform fuse monitoring.
- Can be installed with busbar brackets.
- When installing busbars, busbars with a thickness of 5/10mm can be converted without losing or breaking components.
- Can change the incoming or outgoing line on the busbar without affecting the internal circuit.
- Can be integrated into various low - voltage systems through various cover plates, or can be integrated into busbar systems with or without bases.
- The rear incoming line unit is highly resistant to contact.
- A separate shaft can be used to remove the fuse, and the fuse can be opened and removed without contact.
- Can be sealed and locked.
Features
Features in Design and Structure
- Can conveniently change the incoming or outgoing line on the busbar, with less switch change (cable from the lower cable outlet of the equipment factory).
- Only one change to the equipment is needed to enable various industrial and infrastructure applications to adopt standard contact protection measures.
- Uniform external dimensions, easy to configure.
Features in Operation and Maintenance
- The optional cable connector with rear protection can provide the best contact protection, even suitable for distribution panels with rear door wiring.
- Innovative design can ensure the safety of equipment and personnel to the greatest extent.
- The fuse can be removed through a separate shaft.
- The switch can be locked and sealed to ensure work safety and prevent unauthorized operation.
Features in Installation
- Only one change to the equipment is needed to convert the incoming or outgoing line on the busbar without affecting the internal circuit.
- Only one change to the equipment is needed to order and install an arc - extinguishing chamber, which can make it have a high short - circuit capacity to improve the electrical value.
- Two transfer (CO) contacts can be installed on the switches of all specifications to indicate the switch position of the busbar bracket.
- All switches adopt comprehensive contact protection measures.
- Box - type terminals can be used for switches of all specifications, which can significantly shorten the installation and wiring time.
- Specifications NH000 and NH1 and NH00 are installed with bayonet - type installation, which is fixed with screws. Compared with fixed installation, the installation time is greatly shortened.
- Specifications NH11, NH2 and NH3 are installed with snap - in type, which is convenient for positioning, and can ensure the reliable contact of large and heavy equipment at the same time.
- The compact structure and the installation of the busbar bracket make it occupy a small space.
- The equipment can be installed on busbars with a thickness of 5mm or 10mm, and conversion and installation do not require losing or breaking components.
Applications
Can be applied to:
3NP1 fuse - type isolating switches can be used to protect and disconnect various electrical loads:
- Motor starter combinations.
- Used in combination with SITOR fuses, can be used to protect frequency converters and soft starters.
- Implement fuse protection for reactive power compensation.
- Cable incoming lines.
- Fuse protection for small loads.
Optimized switches can be used in the following system environments:
- Used in low - voltage switch cabinets at power distribution and electrical control centers (such as main distribution panels and distribution panels).
- Protection covers are for power distribution systems with 32/70mm or 45 and 70mm.
- Mechanical engineering.
- Railway applications.
Fuse monitoring for detection, indication and fault reporting:
- MFM - A: AC/DC power grid for electromechanical fuse monitoring.
- EFM10 - A: For AC power grid, electronic fuse monitoring.
- EFM20 - A: For AC power grid, electronic fuse monitoring and power grid monitoring.
- EFM25 - D: For DC power grid, electronic fuse monitoring and power grid monitoring.
Standards and Specifications
3NP1 fuse - type isolating switches comply with the following standards:
- IEC60947 - 1, EN60947 - 1
- IEC60947 - 3, EN60947 - 3
- GB14048.3 - 2008
Installation
- Surface installation.

The Sequence Regulation of Low-Voltage Fuses and Low-Voltage Switches (Including Circuit Breakers) in Circuits
The sequence of low-voltage fuses and low-voltage switches (including circuit breakers) in a circuit depends primarily on the core protection objectives of the circuit, the functional positioning of the equipment, and specific application scenarios; it is not absolutely fixed. The design of "connecting the fuse after the air switch" in machine tool distribution boxes is essentially an optimized protection logic tailored to the special power consumption needs of machine tool equipment, rather than a violation of general principles.Read More September 19, 2025
