It occupies two modular width units (36 mm) on a DIN rail and is designed for residential building and infrastructure DC branch circuits. ## What the ratings mean for fit The 440 V DC maximum operating voltage and 10 kA interrupting capacity define the fault-clearing capability for DC circuits up to that voltage and prospective short-circuit current — critical for photovoltaic strings, DC distribution panels, or battery-backed loads where AC breakers cannot reliably extinguish a DC arc. The C-curve (magnetic trip between 5 and 10 times rated current) suits moderate inrush loads like small DC motors, contactor coils, or capacitive filter banks, but not high-inrush transformers or purely resistive circuits where a B or D curve would better match. The 2-pole design switches both conductors, and the neutral is not switched internally — confirm your circuit requires both poles fused. The IP20 rating (with connected conductors) means it is suitable for enclosed distribution boards only, not for wet or dusty environments without an outer enclosure. ## Integration and mounting Mounts on a DIN rail in any position, with a 70 mm installation depth behind the panel. The 36 mm width (2 modular units) matches standard SENTRON comb-busbar spacing and accessory footprints. Sealable design allows lockout/tagout compliance. Halogen-free and silicon-free construction suits environments sensitive to outgassing — data centers, medical, or clean-room infrastructure.","metaTitle":"Siemens SENTRON 5SL5201-7RC DC Miniature Circuit Breaker, 44","metaDescription":"Siemens SENTRON 5SL5201-7RC DC miniature circuit breaker, 440 V DC, 10 kA interrupting capacity, 2-pole, C-curve.
