DC-rated MCB for control and auxiliary circuits
The Siemens SENTRON 5SY5115-7CC is a 1-pole miniature circuit breaker rated for DC circuits at 220 V (max 250 V) with a C tripping characteristic and a 1.6 A current rating. This is a DC-specific device, not a dual-rated AC/DC breaker.
Ambient range from -40 °C to 75 °C, with humidity derating above 55 °C: max 95% RH at 55 °C, dropping to 35% RH at 75 °C.
Halogen-free and silicon-free construction meets material restrictions common in automotive, rail, and semiconductor fab environments. The sealable design allows panel builders to lock the toggle position after commissioning — useful for preventing unauthorized reset on safety-critical DC circuits.
