Fastens via the quick-assembly system — snaps onto the rail without tools. Mounting position is any orientation; supply cord position is also any, which simplifies wiring in tight enclosures. ## Environmental and material specs Rated for ambient temperatures from -40 °C to 75 °C, with humidity derating: max 95% RH at 55 °C, tapering to 35% RH at 75 °C. Halogen-free and silicon-free construction — important for panels in semiconductor fabs or clean rooms where outgassing can contaminate optics or contacts. Sealable terminals (top and bottom combined) allow lockout/tagout compliance.","metaTitle":"Siemens SENTRON 5SY4325-7 MCB, 3P, C-curve, 10 kA IEC/EN 608","metaDescription":"Siemens SENTRON 5SY4325-7 miniature circuit breaker, 3-pole, C-curve, 10 kA (IEC/EN 60898-1), 20 kA (IEC 60947-2).
