Eaton MCBs: Three Generations of Memshield Breakers

This page is the MCB shelf of the Eaton catalogue: nearly two hundred and fifty miniature circuit breakers spanning three Memshield generations, so the board in front of you can be matched whatever its age.

Memshield 3 EMCH breakers serve current boards, like the EMCH363 63A triple-pole Type C at 10 and 15kA. Memshield 2 keeps the MBH and MCH series alive from 1A single-pole upward, and even Memshield 1 units such as the 161MB and the triple-pole 163MC and 203MB remain here for the oldest serviceable boards.

Electrical2Go holds all three generations at trade prices with fast UK delivery.

Eaton MCBs by Generation

Identify the board generation first; the right breaker follows.

Memshield 3: EMCH-series breakers for current Eaton boards: single and triple pole, B and C curves, with high-rated units like the 63A EMCH363 for sub-main circuits.

Memshield 2: the MBH (Type B) and MCH (Type C) series at 10kA, from the 1A MBH101 up, keeping the huge installed base of Memshield 2 boards serviceable.

Memshield 1: legacy single and triple pole units, like the 161MB, 163MC and 203MB, for boards old enough that the alternative is a full board change.

Why buy Eaton MCBs from Electrical2Go

A tripped-and-failed MCB is a same-day problem, and generation matching is what stops a wasted trip: Memshield generations do not interchange. We keep all three on the shelf together, and this page sits inside our full Eaton range alongside the RCBOs, MCCBs and distribution boards.

Every breaker ships from genuine current-catalogue Eaton stock at trade prices with fast UK delivery.

Frequently Asked Questions

The device series is the quickest tell: EMCH prefixes are Memshield 3, MBH and MCH are Memshield 2, and plain numeric codes like 161MB are Memshield 1. The board label confirms it.

No. The busbar and case designs differ between generations, so a breaker must match its board series. That is why this page keeps all three generations in stock.

Type B trips between three and five times rated current and suits general and domestic circuits; Type C tolerates five to ten times for motor and discharge-lighting inrush, the common pick in commercial boards.

The fault current the breaker can safely interrupt: the MBH and MCH series are 10kA units, and models like the EMCH363 carry 10/15kA ratings for supplies with higher prospective fault current.

Yes, three-phase circuits are covered across the generations, from the current EMCH363 back to Memshield 1 triple-pole units like the 163MC.
