Factory Supply KNBL1-32 1P+N Residual Current Circuit Breaker 50/60Hz

You'll typically use this for residential distribution boards, where the end-user is a tenant who just needs the lights to stay on and the occasional power tool run without nuisance tripping — it handles that pretty well.

We've got these in regular stock with the C curve, rated current form 6A up to 32A, depending on what your job calls for, and breaking capasity is 6000A at 240V AC. They're CE and CB certified, so you're covered for most European-type installations, though the box says IEC/EN61009-1 and GB16917.1.

The mechanicla life is rated at 4000 operations, but electricla life is actually 20000 — which is what it is. One detail most buyers don't think to ask about: the relative humidity tolerance is ≤95% at +40°C, so it'll hold up fine in a damp basement or a boiler room as long as it's not condensing water on terminals.

Basically, it's a manual-reset unit, fixed instalation, air arc extinguishing — nothing exotic, just a solid 1P+N that trips on both AC and type A leakage sensitivity. The operating range is -5°C to +40°C, though storage can go down to -25°C or up to +70°C (usually 2-4 weeks, check lead time if you need a rush).

We don't have MOQ issues on these — most times, our company can ship single units or full boxes, but confirm lead time for anything outside the 6A to 32A range because we don't always hold the odd sizes. Anyway, it's not suitable to three-phase commercial boards, so if you're wiring up a workshop, grab something else.
