The 1P+N design switches the neutral, so you get full isolation on both poles in one 36 mm-wide module. At 50 kA per IEC 60947-2 (AC) and 15 kA per the same standard at 72 V DC, this breaker handles fault levels typical of main distribution boards in industrial environments. The C-curve (5–10× In) suits motor and transformer inrush without nuisance tripping. For UL 1077 recognition, the interrupting rating is 5 kA — confirm your panel's SCCR against that figure if the job falls under North American code. Ambient range spans –40 °C to 75 °C, but note the derating: at 50 °C the continuous current drops to 3.88 A, at 55 °C to 3.75 A. ## Material compliance and vibration Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz. Sealable terminals allow tamper-proofing after commissioning.","metaTitle":"Siemens 5SY8504-7 SENTRON MCB, C-Curve 4A, 2-Pole 1P+N, 50kA","metaDescription":"Siemens 5SY8504-7 SENTRON miniature circuit breaker, C-curve, 4 A, 2-pole (1P+N), 50 kA breaking capacity per IEC 60947-2.
