Custom OEM ODM WSB1L MCB Circuit Breaker with CE CB CCC Certification for Power Distribution

A facility manager in a mid-sized commercial building needed something compact but relaible for the distribution panel, and we've handled a few similar requests where the 1P+N at 36mm was basically the only way to fit everything without reworking the whole enclosure.

You're looking at rated currents from 10A all the way up to 63A, with breaking capacities of 6kA or 10kA depending on what your local grid demands — the 10mA residual current setting is pretty much overkill for most, but it's there if you need it for sensitive equipment, and the 3P+N variant runs at AC400V while the single-phase version tops out at 240V.

For residential complexes, most buyers go with the 30mA leakage setting, though it's not suited for outdoor installations with wide tempearture swings since the operating range is -5°C to +40°C, but in a standerd indoor panel it holds up fine, and the manual operation (usually 4000 cycles or so) is enough for typical use.

Anyway, our company have stock on the common ratings like 16A and 32A, but teh 63A option (check lead time) might need a week extra from the factory, and terminal capacty at 25mm² top and bottom handles most wiring without issues.
