Ambient temperature range spans -40 °C to 75 °C, with humidity influence capped at 95% up to 55 °C, 55% up to 70 °C, and 35% at 75 °C. The lifecycle status is current production. Width is 36 mm (2 modular units), depth 76 mm, height 90 mm, installation depth 70 mm. Fastens via the quick assembly system in any mounting position. Combined top and bottom terminals simplify daisy-chaining. Halogen-free and silicon-free construction.","metaTitle":"Siemens 5SY5210-7CC11 SENTRON MCB, 2P C-curve 10A DC 440V","metaDescription":"Siemens SENTRON 5SY5210-7CC11 miniature circuit breaker, 2-pole C-curve 10A, DC 440V breaking 10kA per IEC 60947-2.
