Energy limiting class 3 keeps let-through energy low, reducing stress on downstream wiring and equipment during a fault. The 18 mm width (1 width unit) matches the standard modular grid; no special end-plate or spacer needed for adjacent breakers. Terminals accept 0.75 mm² to 25 mm² solid or stranded copper — covers the full range from 1.5 mm² lighting circuits up to 6 mm² feeder tails. IP20 protection with connected conductors; suitable for dry indoor enclosures only. Sealable with a lead seal or adhesive label to prevent unauthorized reset after commissioning. Rated for ambient temperatures up to +55 °C with 95% humidity, and vibration resistance of 50 m/s² at 25 to 150 Hz per IEC 60068-2-6. Overvoltage category 3, pollution degree 2 typical for fixed-installation distribution boards.","metaTitle":"Siemens 5SL4125-6CC SENTRON MCB, 1P B 25A 10kA","metaDescription":"Siemens 5SL4125-6CC SENTRON miniature circuit breaker, 1-pole, B-curve, 25 A, 10 kA breaking capacity per EN 60898.
