Product details

The Siemens 5SV4344-0 is a SENTRON 4-pole residual current circuit breaker (RCCB), Type AC, rated 40 A with 30 mA sensitivity at 400 V AC. That's standard for a domestic or small commercial DB fed from a transformer of similar rating.

DIN-rail fit and panel integration

Overall dimensions are 72 mm wide × 90 mm high × 70 mm deep — the depth matches the standard installation depth, so it sits flush with the front of a typical distribution board without protruding into the cable duct. Mounting position is unrestricted, and supply can enter from top or bottom, which simplifies busbar and cable routing in a crowded enclosure.

Frequently asked questions

What is the 5SV4344-0 used for?

It's a 4-pole Type AC residual current circuit breaker (RCCB) rated 40 A / 30 mA / 400 V AC, used for earth-fault protection in residential and light commercial distribution boards. The 30 mA sensitivity provides personal shock protection; the 10 kA SCCR handles fault currents typical of domestic supply.

Where can I buy the 5SV4344-0?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock figures or lead-time numbers are published here.

Will the 5SV4344-0 drop into a panel specified around a 5SL4363-7 miniature circuit breaker?

Not without rewiring — the 5SV4344-0 is a 4-pole RCCB (72 mm wide, 4 MW), while the 5SL4363-7 is a 3-pole MCB (54 mm wide, 3 MW). They share the same 90 mm height and 70 mm installation depth, but the RCCB occupies one extra width unit and serves a different protection function (residual current vs. overcurrent). A panel designed for the MCB would need a wider DIN-rail slot and separate overcurrent protection upstream or downstream of the RCCB.
