xPole Combined RCD/MCB Device PKP42, 2-pole

This residual current operated circuit breaker with integrated overcurrent protection in 2-pole is a high-quality residual current circuit breaker and miniature circuit breaker combination. The line voltage independent PKP42 is part of the xPole series and can be used for residential buildings as well as for commercial applications.

A red-green contact position indicator and a white-blue fault tripping indicator makes it immediately apparent what is going on: 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. The combined RCD/MCB device is compatible with standard busbars, a twin-purpose terminal (lift/open-mouthed) is available for quick and easy mounting at the top and as well as at the bottom. In addition, a 3-position DIN rail clip and a secure terminal connection serve as an installation guide/help.

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 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.

Detects pure sinusoidal AC residual currents

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 nuisance tripping can be prevented by individually wiring the system with several circuit breakers.

  • Type AC: This type only detects pure sinusoidal AC residual currents.

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.
