Circuit breakers

This residual current operated circuit breaker with integrated overcurrent protection is a high-quality residual current circuit breaker and miniature circuit breaker combination with line voltage-independent tripping and a wide variety of rated tripping currents.

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. It is compatible with busbars. A twin-purpose terminal (lift/open-mouthed) is available for easy and quick mounting.

IEC Standard quality design

The RCBO line adheres to the IEC standard of VDE 0664-20 and 21 – 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.

Suitable RCD/MCB types for all contingencies

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

Type -Super A: High reliability against unwanted tripping. Compulsory for any circuit where personal injury or damage to property may occur in case of unwanted tripping.

Type AC: This type only reliably detects AC fault currents.

Type G: High reliability against unwanted tripping. Compulsory for any circuit where personal injury or damage to property may occur in case of unwanted tripping.

Typ F: Higher load rating with DC residual currents up to 10 mA. Increased protection in applications with 1-phase frequency converter due to the detection of mixed frequencies.

All in one device

Eaton's high quality standard guarantee comprehensive personal- and equipment protection by combining the functionalities of a residual current circuit breaker with those of a miniature circuit breaker all in one device. 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.
