Product details

The Siemens 5SJ4132-8HG42 is a 1-pole SENTRON miniature circuit breaker with a D tripping characteristic, rated 32 A at 400 V AC and 60 V DC. It clips onto a standard mounting rail (35 mm DIN) and occupies one width unit (18 mm), which keeps the panel fill factor tight.

Breaking capacity and standards

Overvoltage category 3, so it's rated for fixed-installation distribution boards.

Mounting and environmental fit

IP20 with connected conductors, IP40 in the handle area — fine for enclosed distribution boards but not for washdown zones. Vibration resistance tested to 50 m/s² at 25–150 Hz and 60 m/s² at 35 Hz (4 s), which covers most industrial machinery environments.

Frequently asked questions

What is the breaking capacity of 5SJ4132-8HG42?

10 kA per EN 60898 and 15 kA per IEC 60947-2. The higher IEC rating means it's suitable for industrial panels with higher prospective fault currents.

Will 5SJ4132-8HG42 drop into a panel specified around 5SY7140-8CC without rewiring?

Both are 1-pole MCBs on a standard DIN rail, but the 5SY7140-8CC is a B-curve 40 A device. The 5SJ4132-8HG42 is D-curve 32 A — same footprint, different tripping characteristic and rating. No rewiring needed if the circuit is rated for 32 A and the load inrush suits D-curve; verify coordination with the upstream protective device.

Where can I buy 5SJ4132-8HG42 and how is it quoted?
