It is designed for DC circuits in residential and infrastructure installations. The C-curve tripping characteristic handles inrush currents typical for lighting and small transformers on a DC bus. Rated for 220 V DC and a 10 kA interrupting capacity, this breaker can safely clear a short-circuit fault up to that level on a DC supply, which is a common requirement for telecom rectifiers, solar combiner boxes, or battery-backed control panels. ## Physical fit and panel integration Occupies 1 modular width unit (18 mm) on a DIN rail, with a depth of 76 mm and height of 90 mm. Mounting position is any; installation depth is 70 mm behind the panel surface. IP20 protection (with connected conductors) means it is suitable for dry indoor enclosures — standard for distribution boards and control cabinets. The terminals are touch-protected per the product feature. Sealable design allows the installer to lock the breaker in the ON or OFF position for lockout/tagout procedures.","metaTitle":"Siemens 5SL5102-7RC SENTRON MCB, 1P C-curve 2A DC 220V 10kA","metaDescription":"Siemens SENTRON 5SL5102-7RC miniature circuit breaker, 1-pole, C-curve, 2 A, 220 V DC, 10 kA breaking capacity.

The key difference is the 5SL5102-7RC is a DC-only breaker (220 V DC, 10 kA) while the 5SL6120-7 is an AC-rated unit (400 V AC, 6 kA).
