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.
