5SV3346-6 Siemens Current Operated Circuit Breaker 63A 4P 400V 30mA Current Monitoring
The Siemens 5SV3346-6 is a high-performance 4-pole miniature circuit breaker (MCB) from the SENTRON 5SY series, designed to provide dependable overload and short-circuit protection in residential, commercial, and light industrial electrical installations. With a rated current of 40 A, a breaking capacity of 6 kA at 400 V AC, and Type C tripping characteristic, this MCB is ideal for circuits powering motors, transformers, lighting systems, and other loads with moderate inrush currents.
Engineered to meet international safety standards including IEC/EN 60898-1 (for household use) and IEC/EN 60947-2 (for industrial applications), the 5SV3346-6 ensures fast, selective disconnection during fault conditions—protecting wiring, equipment, and personnel. Its compact 18 mm per pole design allows efficient use of space in distribution boards, while the robust thermal-magnetic trip mechanism delivers consistent performance over time and across temperature variations.
