No separate neutral switch; uses the busbar for shared neutral on 3-phase circuits. ## Environment & vibration Rated –40 to 75 °C ambient, so it can sit in an unconditioned roof space or a freezer plant without derating. Vibration resistance of 50 m/s² (25–150 Hz) and 60 m/s² (35 Hz, 4 sec) covers most rotating machinery floors. IP20 with conductors connected, IP40 in the handle area – sufficient for panel interiors; a separate door seal isn't needed.","metaTitle":"Siemens 5SJ4330-8HG42 Miniature Circuit Breaker, 3P D-Curve","metaDescription":"3-pole D-curve MCB, 10kA (EN 60898)/15kA (IEC 60947-2), AC 400V, 70mm depth, DIN rail.
