This Schrack 10A B-curve circuit breaker (MCB) monitors a single circuit and switches it off in the event of an overload or short circuit. With a rating of 10 A, it is intended for low-power circuits. After a trip, you switch the toggle back on once the cause has been dealt with.
What is a 10 A B-curve MCB used for?
- indoor or outdoor lighting, for example a long circuit to the garden or an outbuilding
- electric roller shutters and external blinds
- a ventilation unit
- a doorbell, garage door or control systems
Many Belgian homes still have a 3×230 V network, in which both conductors of a circuit are phase conductors. This 2-pole MCB protects both of them; in a 3N×400 V network, it protects the phase and the neutral.
Benefits of the Schrack BMS4
- B tripping curve: trips magnetically from as little as 3 to 5 times the rated current, even when the short-circuit current on a long cable remains low
- breaking capacity of 4.5 kA to EN 60898-1 and 6 kA to EN 60947-2
- a window on each pole that shows red or green to indicate whether the contact is closed
- lockable toggle, handy when work is being carried out on the circuit
Good to know
A lot of LED lighting on one circuit causes a brief current surge at switch-on; a C-curve MCB is usually chosen for that. Have the MCB installed by a qualified electrician. A new or modified installation must then be inspected by an approved inspection body.
