ABB System Pro M Compact S200M MCB, 2P, 20A Curve B, 440V AC, 125V DC, 10 kA Breaking Capacity

ABB System pro M compact S200M miniature circuit breakers are current limiting. They have two different tripping mechanisms, the delayed thermal tripping mechanism for overload protection and the electro mechanic tripping mechanism for short circuit protection. All MCBs of the product range S200M comply with IEC/EN 60898-1 and IEC/EN 609 47-2, allowing the use for residential, commercial and industrial applications. Bottom-fitting auxiliary contact can be mounted on S200M to save 50% space

IEC 60898 - Relates to Low Voltage Circuit Breakers for use in household and similar
Installations. In the UK traditionally known as miniature circuit breakers
(MCB’s).
IEC 60947-2 Relates to Low Voltage Circuit Breakers for use in industrial and similar
Installations. In the UK traditionally known as moulded case circuit breakers
(MCCB’s) and also air circuit breakers (ACB’s).

A Curve B: Tripping: 3 to 5 times the rated current.
Applications: protection of generators, persons, very long cables

These are an economy range of MCB's and as such do not accept common accessories, these items will not fit compact boards (System Pro-M).

This miniature circuit breaker (MCB) protects electrical circuits from overloads and short circuits. It features a 2-pole configuration with a current rating of 20A and a breaking capacity of 10kA at a rated operational voltage of 440V AC.
