Product details

Product identity and ratings

The Siemens 5SL4404-7RC is a SENTRON miniature circuit breaker (MCB) with four poles, a C tripping characteristic, and a 4 A rated current at 415 V AC. Its 10 kA breaking capacity per EN 60898 means it can safely clear a fault up to 10,000 A at that voltage — adequate for most residential and light commercial sub-distribution boards where the prospective short-circuit current is known to be under that threshold.

At 18 mm wide (one modular unit), 90 mm tall, and 76 mm deep, this breaker occupies a single DIN-rail slot.

Environmental and material specs

Rated for ambient temperatures from -40 °C to 75 °C, the 5SL4404-7RC suits unconditioned outdoor cabinets or attic-mounted panels.

Frequently asked questions

What is the breaking capacity of 5SL4404-7RC?

The 5SL4404-7RC has a 10 kA breaking capacity per EN 60898 at 415 V AC.

Will 5SL4404-7RC drop into a panel that was specified around 5SL3116-6MB without rewiring?

Both share the same 18 mm width per pole, 76 mm depth, and 90 mm height, so the physical footprint is identical. However, the 5SL4404-7RC is a 4-pole C-curve 4 A breaker, while the 5SL3116-6MB is a 1-pole B-curve 16 A unit — the pole count, trip characteristic, and current rating differ, so the wiring and circuit design must match the new breaker's ratings.

Where can I buy 5SL4404-7RC?
