The 1P+N pole arrangement switches the line conductor and switches the neutral without overcurrent protection on the neutral leg — standard for single-phase final subcircuits in distribution boards. At 50 A it's sized for high-demand single-phase feeds: large commercial cooking equipment, air handlers, or sub-panel mains. Ambient temperature range is -20 to +45 °C operating, -40 to +75 °C storage. Vibration resistance tested to 50 m/s² at 25–150 Hz and 60 m/s² at 10–150 Hz per IEC 60068-2-6. Insulation voltage rated 440 V AC, overvoltage category III. Mechanical endurance is 20,000 switching cycles typical.","metaTitle":"Siemens 5SJ6550-7 SENTRON MCB, 1P+N, C-Curve, 50 A, 6 kA","metaDescription":"Siemens 5SJ6550-7 SENTRON miniature circuit breaker, 1P+N, C-curve, 50 A, 6 kA per EN 60898.
