Rated operational voltage is 400 V AC (single- or multi-phase) and 220 V DC, with a maximum DC voltage of 250 V. This covers standard 230/400 V distribution panels and 220 V DC control circuits. Designed to IEC / EN 60898-2 and UL1077, meaning it's accepted for both IEC and UL-style panels — a dual-cert part that avoids a separate UL-listing requirement in mixed-spec jobs. Halogen-free and silicon-free construction. Width is 18 mm (1 modular unit), depth 76 mm, height 90 mm, installation depth 70 mm. Combined terminals top and bottom; neutral conductor not switched. Sealable. ## Sourcing and verification Each unit carries the Siemens SENTRON brand mark and a date code on the side. Verify the lot number against the manufacturer's traceability database if counterfeit risk is a concern — remarked parts in this class often have mismatched font on the rating plate or a missing UL logo.","metaTitle":"Siemens 5SY5114-7 SENTRON MCB, 1P C-curve 10kA, 400V AC","metaDescription":"Siemens 5SY5114-7 SENTRON miniature circuit breaker, 1-pole C-curve, 10kA breaking capacity per IEC/EN 60898-2, UL1077.
