Product details

The Siemens 5SV3344-6GV02 is a SENTRON 4-pole residual current circuit breaker (RCCB) rated 40 A at 40 °C, tripping at 30 mA — Type A, instantaneous. Type A catches pulsating DC faults from electronics or rectified loads, not just pure sine-wave AC.

Snaps onto DIN rail (REG profile), mounting position any — no orientation restrictions. Supply can enter top or bottom. Rated IP20 once installed with conductors connected — it's an enclosed-panel device, not for wet environments.

Thermal derating — the number that matters

The 40 A rating holds only at 40 °C ambient. Above that, the continuous current drops fast: 38.1 A at 45 °C, 35.59 A at 50 °C, 32.29 A at 55 °C, 28.19 A at 60 °C, 23.3 A at 65 °C, 17.62 A at 70 °C. Factor that into the load schedule.

Current production — no phase-out or NRND flag on this order code.

Frequently asked questions

What is 5SV3344-6GV02's depth?

70 mm, matching the installation depth. That's the body depth on the DIN rail; clearance needed above and below for conductor bending is separate.

What is 5SV3344-6GV02's width?

72 mm, which is 4 modular width units (18 mm per unit). Fits a standard 4-MW cutout in a distribution board.

Where can I buy 5SV3344-6GV02?

This part is sourced to order against an RFQ through independent industrial-automation distribution. Submit an RFQ for current pricing and availability, confirmed at quote time.
