That 15 kA rating under the industrial standard gives headroom for higher fault-current panels; the 10 kA figure is the residential/commercial floor. Rated 440 V AC for both single-phase and multi-phase operation. DC rating maxes at 72 V — useful for control-circuit protection but not for high-voltage DC bus work. Rated 2.2 A at 30 °C, derated to 1.9 A at 60 °C. That derating curve matters when packing multiple units side by side in a DIN rail row. Mounts in any position, occupies 1 modular width unit (18 mm wide). Halogen-free and silicon-free construction.","metaTitle":"Siemens 5SL4102-0RC Betagard MCB, 2A 1P Z-Char 10kA","metaDescription":"Siemens Betagard 5SL4102-0RC miniature circuit breaker, 2A, 1-pole, Z characteristic, 10kA per EN 60898.
