Product details

What this MCB does and where it fits

Snaps onto standard DIN rail. Occupies 3 width units (roughly 54 mm of rail space) and installs at 55 mm depth — typical for SENTRON 5SQ modular devices. The neutral pole switching (marked as 3P+N) means you don't need a separate neutral link for the outgoing circuit; the breaker itself opens the neutral when tripped. IP20 rated, so it's intended for enclosed distribution boards or control cabinets, not for direct outdoor exposure.

Energy limiting class 3 means this breaker limits let-through energy well — useful for downstream equipment protection and for achieving selectivity with upstream devices.

Frequently asked questions

What is the closest functional second-source for 5SQ2670-0KA10?

The 5SQ2670-0KA15 is the same 4-pole 3P+N C-curve breaker but rated 15 A instead of 10 A. It shares the same 3 kA breaking capacity, 55 mm depth, and 3 width units — so it drops into the same panel footprint without rewiring, provided the load current allows the higher rating.

Will 5SQ2670-0KA10 drop into a panel specified around 5SQ2670-0KA15 without rewiring?

Yes — both breakers share the same 4-pole 3P+N configuration, 55 mm depth, 3 width units, and DIN-rail mounting. The only difference is the current rating (10 A vs 15 A). If the circuit is designed for 10 A, the 5SQ2670-0KA10 fits physically and electrically without any wiring change.

Where can I buy 5SQ2670-0KA10 and how is it quoted?
