Series Overview
Residual Current Release (RCD)
All Tmax series circuit breakers and switch-disconnectors can be equipped with a Residual Current Release. T1, T2, and T3 circuit breakers can be used with the new IC221 or IC222 series Residual Current Releases; 4-pole T4/T5 circuit breakers can be used with the BC222 Residual Current Release; T6 and T7 circuit breakers can be used with the BCQ Residual Release.
In addition to providing overload protection and delayed short-circuit protection functions like an electronic trip unit, this Residual Current Circuit Breaker (RCCB) also offers protection against electric shock (both direct and indirect contact) and fire hazards caused by residual currents. The RCCB can continuously monitor the insulation status of electrical equipment, providing effective protection against fire and explosion accidents.
The Residual Current Release can also be installed on T1D, T2D, T3D, T4D, and T5D switch-disconnectors. In this configuration, it functions as a 'pure' Residual Current Circuit Breaker, sensitive only to earth fault currents. It is primarily used as the main switch-disconnector in small distribution switchboards for end-users. Both 'pure' and 'non-pure' Residual Current Circuit Breakers can be used to continuously monitor the insulation status of electrical equipment, effectively preventing fires and explosions. When IΔn ≤ 30mA, they provide protection against direct and indirect contact electric shock, complying with relevant standards and accident prevention regulations.
Residual Current Releases comply with the following standards: IEC 60947-2 and IEC 61000.
- IC221 and IC222 utilize advanced electronic technology, directly operating the circuit breaker via a trip coil (installed in a special slot on the left side) matched to the Residual Current Release. They do not require an additional auxiliary power supply, drawing power directly from the mains. They function correctly even with only single-phase or 2-phase voltage and with single-phase pulsating currents containing a DC component.
- The Residual Current Release is equipped with the following accessories:
- Trip coil installed in the special slot on the left side and an auxiliary contact indicating Residual Current Release tripping.
- Dedicated flange.
- RC221 and RC222 have a signal indication changeover contact for residual current protection tripping. RC222 has two additional changeover contacts for pre-alarm and alarm signal indication.
- A circuit breaker cannot simultaneously be equipped with a Residual Current Release, a stacked electromagnetic operating coil (MOS installed side-by-side with T1 and T2 can be installed together), or a rotary handle.
Residual Current Release - RC221 and RC222
- RC221 and RC222 are suitable for 3/4-pole fixed-mounted T1, T2, and T3 circuit breakers. The Residual Current Release is powered directly from the mains, requiring no auxiliary power supply. RC221 and RC222 can be powered from either the top or bottom terminals. Their operation can be continuously monitored via a test button and a magnetic indicator for residual current tripping. 4-pole circuit breakers with a Residual Current Release can be equipped with electrical accessories - shunt trip or undervoltage release - but this is not applicable to 3-pole circuit breakers.
- For T2 and T3 circuit breakers, since only front cable connection for copper cables (FC Cu) is possible at the bottom of the Residual Current Release, the FC Cu front terminals must be supplied together when ordering the Residual Current Release.
- For 4-pole T1 circuit breakers, HR rear horizontal terminals can also be installed at the bottom of the Residual Current Release. Simultaneously, the BC222 for 200mm modules can be installed. This BC222 release has the same technical parameters as the standard RC222 Residual Current Release used for T1, T2, and T3, but its height is significantly reduced, allowing installation within a 200mm module. When two or more modules are installed side-by-side, their dimensions are very compact. Upon request, brackets for fixing to DIN 50022 rails are also available.
- T1, T2, and T3 circuit breakers cannot simultaneously be equipped with a Residual Current Release, a front-mounted electromagnetic operating mechanism (MOS), or a rotary handle operating mechanism.
- BC222 is suitable for installation under 4-pole T4 and T5 circuit breakers. Front terminals are standard and compatible with all Tmax terminal types. T4 and T5 circuit breakers cannot simultaneously be equipped with a Residual Current Release and a stored-energy motor operating mechanism.
- The fixed-mounted Residual Current Release RC222 can be conveniently converted to plug-in and withdrawable versions using a special conversion kit.
