Product details

The Siemens 5SP4380-8 is a SENTRON 5SP-series miniature circuit breaker (MCB) with a D tripping characteristic, 3 poles, rated 80 A at 400 V AC, and a breaking capacity of 10 kA per EN 60898. It fits a standard DIN rail and screw fixing, occupies 4.5 modular width units, and installs in any orientation.

Sealable, halogen-free, silicon-free — suitable for environments where outgassing or contamination must be controlled. Withstands shock at 150 m/s² for 11 ms half-sine and vibration at 50 m/s² from 25 to 150 Hz, per IEC 60068-2-27 and IEC 60068-2-6.

Frequently asked questions

What is the depth of the 5SP4380-8?

The overall depth is 76 mm, with an installation depth of 70 mm.

Will the 5SP4380-8 drop into a panel specified for the 5SP4380-7?

Both are 3-pole D-curve MCBs in the same SENTRON 5SP family with identical dimensions (76 mm depth, 81 mm width, 90 mm height) and mounting (DIN rail and screw fixing), so no rewiring or panel modification is needed for the swap.
