ABB System Pro M Compact S200 Miniature Circuit Breaker, 2-Pole, 16 A, Type B, 400 V ac AC, 110 V DC

Use this MCB from ABB to safeguard your equipment from short circuits and overload currents. Thanks to its 2-pole construction, you can use it to protect 2 separate circuits at the same time. With dimensions of 69 (L) x 35 (W) x 88mm (H), it's a compact choice for use in setups with limited space. Type-B tripping characteristics mean the unit cuts power at 3 to 5 times its rated current of 16A. This makes it suitable for sensitive equipment like domestic appliances.

• IP20 rating means that it's finger-safe and protected from objects larger than 12mm in size

• Office buildings

To ensure this MCB works at its best, periodically check and tighten loose fasteners and ensure there's no debris on the contacts. You should carry out maintenance at least once a year.
