Product details

The Siemens 5SJ6210-6KS is a SENTRON miniature circuit breaker (MCB) — 2-pole, B-curve, rated 10 A at 400 V AC, with a 6 kA breaking capacity certified to both EN 60898 and IEC 60947-2. Two-pole design (2P) switches both phase and neutral, common in single-phase final subcircuits where disconnection of both conductors is required.

Mounting and environment

Pollution degree 2 (non-conductive, occasional condensation) covers the typical control cabinet environment. Ambient storage range from -40 °C to +75 °C; operating ambient is -20 °C to +45 °C with periodic excursions to +55 °C at up to 95% humidity.

Frequently asked questions

Where can I buy 5SJ6210-6KS and how do I get a price?

This part is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What is the breaking capacity of 5SJ6210-6KS?

6 kA rated breaking capacity per EN 60898 and IEC 60947-2 at 400 V AC.

What is the difference between 5SJ6210-6KS and 5SJ6216-6?

The 5SJ6216-6 is the 16 A variant of the same 2-pole B-curve 5SJ6 platform — same footprint, same 6 kA breaking capacity, same terminal range. The only difference is the current rating (10 A vs 16 A). It drops into the same panel position without rewiring.
