Eaton Protective Devices: MCBs, RCBOs and MCCBs

This page holds the protective devices that populate Eaton distribution boards: three hundred MCBs, RCBOs and MCCBs, most of them from the Memshield 2 and Memshield 3 families that dominate UK commercial boards.

The grid runs from single-pole 10kA Memshield 2 MCBs like the MBH101 and MCH108 up to triple-pole 63A units such as the EMCH363, with Memshield 3 EMCH RCBOs covering Type B and C curves at 30mA and the xPole AFDD+ family adding arc fault detection.

Electrical2Go stocks the device catalogue alongside the boards they fill, at trade prices with fast UK delivery.

The Eaton Device Ranges

Match the device family to the board it protects.

Memshield 3: the current generation: EMCH-series MCBs and RCBOs, like the 32A 10kA Type C 30mA single-phase RCBO and the EMCH125R30C 25A single-pole unit, for Memshield 3 boards.

Memshield 2: the legacy family that keeps thousands of existing boards serviceable: MBH and MCH series MCBs from 1A up, in B and C curves at 10kA.

xPole AFDD+: arc fault detection devices that combine AFDD, RCBO and MCB protection in one module for circuits where arc faults are the risk.

Why buy Eaton devices from Electrical2Go

Board work is generation-specific: a Memshield 2 board needs Memshield 2 devices, and fitting the wrong series is a compliance problem, not a preference. This page keeps both generations in stock side by side, and it is one slice of our full Eaton range, where the matching distribution boards live.

Every device ships from genuine current-catalogue Eaton stock at trade prices with fast UK delivery, whether you need one replacement MCB or a board-full of RCBOs.

Frequently Asked Questions

No, the generations are not interchangeable: Memshield 2 boards take MBH and MCH series devices, Memshield 3 boards take the EMCH series. Match the device family to the board before ordering.

An MCB protects against overload and short circuit only; an RCBO adds 30mA earth fault protection in the same module, protecting one circuit without tripping its neighbours.

Type B trips at lower inrush and suits domestic and general circuits; Type C tolerates the higher inrush of motors and discharge lighting, which is why it dominates commercial boards like the ones this page serves.

Arc fault detection: they combine AFDD, RCBO and MCB functions in one device for circuits where damaged cables or loose terminations pose a fire risk.

Above the MCB ceiling: MCCBs on this page handle the higher frame ratings for sub-main and supply-side protection in commercial installations.
