Product details

Railway-rated 32 A B-curve MCB

That SCCR matches typical railway sub-distribution panels fed from a 400 V transformer. The 2-pole construction switches both phase conductors simultaneously — required for single-phase 400 V line-to-line loads or for two-pole protection on a 230 V line-to-neutral circuit where the neutral is switched.

Current production — railway spec

The railway designation means the breaker meets the vibration, shock, and temperature cycling requirements of EN 50155 (electronic equipment for rolling stock) and EN 61373 (shock and vibration). The 32 A B-curve is a common spec for auxiliary power distribution in railcars and locomotives.

DIN-rail panel integration

The 2-pole width is 36 mm (2 module units), so it occupies two 18 mm spaces in a distribution board or railcar panel. The B-curve avoids nuisance tripping on cable charging currents in long runs.

Frequently asked questions

What is the difference between 5SY4232-6CC11 and 5SY4232-6CC10?

The 5SY4232-6CC11 is the railway-rated variant (EN 50155/EN 61373) of the 32 A B-curve 2-pole MCB. The 5SY4232-6CC10 is the standard industrial/commercial version without the railway qualification. Both share the same electrical ratings — 400 V, 10 kA, 32 A, B-curve — but the -6CC11 adds vibration and shock testing for rolling stock environments.

Is the 5SY4232-6CC11 suitable for railway rolling stock applications?

Yes, this MCB is explicitly designed for railway applications per the manufacturer description. It meets the environmental and electrical requirements for auxiliary power distribution in railcars, locomotives, and wayside equipment operating on 400 V AC systems.

Can the 5SY4232-6CC11 be used for DC applications?

The available specifications only list 400 V AC rating. DC interrupting capacity is not stated for this order code. For DC railway auxiliary circuits (110 V DC or 24 V DC), use a Siemens DC-rated MCB from the 5SY4 DC series.
