xPole Combined RCD/MCB Device mRB4/6, 3+N-pole

The mRB4/6 is a line voltage-independent electromechanical residual current device with integrated overload protection. The mRB4/6 devices in 3+N pole are available as "type A" and with rated currents from 20 to 32 A (mRB4) and 6 to 16 A (mRB6) .  

A red-green contact position indicator and a white-blue fault current tripping indicator make it immediately apparent what is happening: green indicates open contacts and red indicates closed contacts. A tripping by a fault current is signalled by the blue display, white indicates that either the MCB part was "tripped" or that it was switched off.

Line- and residual current protection

Eaton's high quality standard guarantees comprehensive personal- and equipment protection by combining the functionalities of a residual current circuit breaker with those of a miniature circuit breaker. This means our customers spend less time and effort wiring while still protecting the system against overload, short circuit and residual current. Using Eaton's line of RCBOs, your electrical system will increase in safety and reliability. By organizing the equipment-, lighting- and socket circuits to several protective switching devices, the impacted circuit can be switched off remotely in the event of a fault.

Suitable RCD/MCB types for all contingencies

Wiring the circuits separately increases the operational safety of an electrical system, because in the event of a ground fault on a separated circuit will allow for that circuit to be opened when tripping limits are exceeded. Often a ground fault can lead to an unintentional disconnection of a residual current protection device when other inputs are protected by the same breaker. This type of nusiance tripping can be prevented by individually wiring the system with several circuit breakers.

  • Type -A: Protects against special forms of residual pulsating DC which have not been smoothed.

IEC Standard quality design

The RCBO line adheres to the IEC standard of IEC/EN 61009 – an IEC region as well as European standard for RCDs with integrated overcurrent protection (RCBOs). This applies to both the line voltage-independent and line voltage-dependent RCDs/MCBs with rated currents up to 125 A for fixed installations.

All requirements of IEC/EN 61009 are 100 % fulfilled by Eaton's RCBO line. All required standards are printed on the devices.

Online configurator - design your own customized configurations

The xComfort KLV series and our switching and protection devices are based on a modular design so that you can assemble any combination you need. In addition to a number of standard pre-wired distribution boards, Eaton also supplies customized configurations on request. If you are not yet sure which type of distribution board is the right fit for you, simply fill in our configurator with ordering function.
