Siemens 5SY4132-7CC — SENTRON 1-pole MCB, C-curve, 10 kA
The 10 kA rated value per EN 60898 is the short-circuit capacity at 230/400 V; under UL 1077 and CSA C22.2 No. 235, the same breaker is rated 5 kA, which governs its use in North American supplementary-protection applications. Single-pole design means it switches only the phase — neutral is not switched, so it pairs with a separate neutral bar or a 2-pole breaker when full isolation is required.
Mounting position is any, which simplifies layout in crowded enclosures.
Rated for ambient temperatures from -40 °C to +75 °C, with humidity derating per: max 95% RH up to 55 °C, tapering to 35% at 75 °C. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz.
