If your downstream loads include electronics with rectifier front ends, a Type A is the minimum you need; a plain Type AC would miss the pulsating DC component. This is a DIN-rail mounted unit for standard 35 mm rail. The 3+N-pole body occupies four module widths (4 MW per the description). In a distribution board, it sits downstream of the main breaker or upstream of individual MCBs on the outgoing circuits. The short-time-delayed 'G' characteristic makes it suitable for sub-mains protection where you need selectivity with downstream instantaneous RCDs — the G type's delay lets the downstream device clear a fault first, avoiding a whole-board blackout for a single branch fault.","metaTitle":"Siemens 5SV3346-6MJ01 RCD Type A, 63A 30mA 10kA 3+N-pole","metaDescription":"Siemens 5SV3346-6MJ01 residual current circuit breaker Type A, 63A, 30mA, 10kA, 3+N-pole, 400V.

The 30 mA sensitivity protects personnel against direct contact, and the 63 A rating handles the full load of a sub-distribution board or large load. The short-time-delayed G characteristic prevents nuisance tripping from surge currents while maintaining fault discrimination with downstream instantaneous RCDs."},{"question":"Where can I buy the 5SV3346-6MJ01?","answer":"This part is available to order through our industrial automation sourcing desk.
