Product details

What this RCCB carries

The Siemens 5SV3442-6MJ01 is a residual current operated circuit breaker Type A, rated 25 A with a 100 mA trip sensitivity, 3+N-pole configuration at 400 V, and a 10 kA breaking capacity. That delay is key for selectivity in a sub-distribution panel — you want the downstream RCCB to trip first, not the upstream main switch.

Mounts on standard DIN rail in a distribution or sub-distribution board. The 3+N-pole format (switched neutral) suits TN-S or TN-C-S systems where the neutral must be disconnected with the phases. The G characteristic (short-time-delayed) lets it coordinate with downstream 10 mA or 30 mA RCCBs in medical or wet-area sub-circuits — the delayed upstream unit stays in while the faster downstream clears the fault.

Frequently asked questions

What does the G characteristic mean on this RCCB?

The G characteristic is a short-time-delayed trip curve — it tolerates brief surge currents (e.g., from capacitor charging or motor inrush) up to a defined duration before tripping, reducing nuisance trips while still clearing ground faults within the delayed window.

Where can I buy 5SV3442-6MJ01 and how is it quoted?

This part is sourced through independent distribution and quoted to order against an RFQ. Availability and current pricing are confirmed at quote time.
