This unit handles series-string solar arrays, DC bus distribution, and UPS output circuits at the higher voltage. Both poles are switched (2P design), so the circuit is positively isolated on line and load sides — no single-pole switching leaving one leg live. ## Panel fit and mounting — 2 MW, any orientation The 5SL5225-7RC occupies 2 modular width units (36 mm) on a DIN rail, with a depth of 76 mm and an installation depth of 70 mm. It fits standard SENTRON distribution boards and sub-distribution panels. Mounting position is unrestricted — vertical, horizontal, or inverted — which simplifies layout in tight enclosures. Sealable (padlockable) per the spec, so it supports lockout/tagout procedures for the panel OEM wireman who needs positive isolation verification. Overvoltage category III and degree of pollution 2 confirm suitability for fixed-installation distribution panels. The product designation as a miniature circuit breaker per EN/IEC standards and suitability for residential buildings/infrastructure covers the compliance baseline. For the quality doc control team: the manufacturer provides RoHS, REACH, and IEC 60898/60947-2 declarations with the standard product documentation.","metaTitle":"Siemens SENTRON 5SL5225-7RC DC MCB, 25 A, C-curve, 440 V DC","metaDescription":"Siemens SENTRON 5SL5225-7RC miniature circuit breaker: 25 A, 2-pole, C-curve, 440 V DC, 10 kA.
