Use this 6A B-curve circuit breaker (MCB) to protect circuits that carry very little current. A B-curve MCB trips at a lower short-circuit current than a C-curve MCB, which is useful for thin or long cable runs. Both poles are protected, so it is also suitable for a 3×230 V network.
When do you choose 6 A with a B curve?
- the power supply for a home automation or control system
- a bell transformer or a small power supply
- an appliance for which the manufacturer specifies 6 A with a B characteristic
B or C curve?
A B-curve MCB trips magnetically at 3 to 5 times the rated current, a C-curve MCB only at 5 to 10 times. The B curve therefore responds faster to a short circuit at the far end of a long cable; the C curve copes better with the inrush current of motors and power supplies. If in doubt, follow your electrician's recommendation or match what is already in your consumer unit.
Benefits

- twin terminals on both sides, for conductors up to 25 mm²
- top or bottom feed, any mounting orientation
- IP20, IP40 with cover
Good to know
Leave the installation to a qualified electrician. If you modify or extend your installation, you must then have it inspected by an approved inspection body, as AREI (the Belgian electrical installation regulations) requires.
