Product details

Siemens SENTRON 5SY5103-7 — 1-pole C-curve MCB

The Siemens 5SY5103-7 is a 1-pole miniature circuit breaker from the SENTRON series, with a C-curve tripping characteristic and a rated breaking capacity of 10 kA per IEC/EN 60898-2 and 15 kA per IEC 60947-2 at 400 V AC. It occupies a single modular width (18 mm) on the DIN rail, making it a standard fit for any 1-MW slot in a distribution board or control panel.

The single-pole design does not switch the neutral — confirm your circuit topology before specifying.

Snap-on DIN-rail mounting (any position), 18 mm width (1 MW), 70 mm installation depth, 76 mm overall depth. Sealable with a lead seal for tamper-proof installations. Halogen-free and silicon-free construction for environments sensitive to outgassing.
