Three poles (3P) with no neutral switching — it breaks all three phases but leaves the neutral continuous. Rated for AC/DC operation, with a maximum DC voltage of 60 V. The 70 mm installation depth and screwless outgoing terminals simplify wiring in a crowded enclosure — no screwdriver needed for the load side, just push in a stripped conductor. ## Deployment context and panel fit At 3 width units (54 mm wide), it occupies three 18 mm module positions in a distribution board. Mounting position is unrestricted, which helps in tight retrofit panels where orientation is constrained. Suitable for residential buildings and infrastructure per the manufacturer's classification. The halogen-free and silicon-free construction matters in environments where outgassing could contaminate sensitive equipment — think data centers, medical facilities, or clean rooms.","metaTitle":"Siemens 5SJ6313-7KS SENTRON MCB, 3-pole C 13 A, 6 kA","metaDescription":"Siemens 5SJ6313-7KS SENTRON miniature circuit breaker, 3-pole, C-curve, 13 A, 400 V AC, 6 kA per EN 60898/IEC 60947-2.
