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.","metaTitle":"Siemens 5SY5103-7 SENTRON MCB, C-Curve 1P 10kA, 400V AC","metaDescription":"Siemens 5SY5103-7 SENTRON miniature circuit breaker, 1-pole C-curve, 10 kA per IEC/EN 60898-2, 15 kA per IEC 60947-2.
