Product details

Selective RCCB for 230/400 V networks

The Siemens SENTRON 5SV3444-8 is a 4-pole selective residual current circuit breaker (RCCB) rated for 40 A at 230/400 V AC, 50/60 Hz.

Selectivity and coordination

The selective design (time-delayed tripping) allows this RCCB to coordinate with downstream 30 mA RCCBs. Under a fault, the 30 mA device trips first, keeping the 5SV3444-8 closed and maintaining supply to the rest of the board. The short-circuit current rating (SCCR) is 10 kA per IEC 61008-1, with a let-through current of 5,200 A and an I²t value of 58,000 A²·s — figures that inform upstream fuse or MCB selection for full discrimination.

Temperature derating and installation

Mounting position is any orientation. Silicon-free construction suits potting or coating processes in sensitive environments.

Frequently asked questions

What is the 5SV3444-8 rated residual current and type?

The rated residual tripping current is 100 mA, Type A (sinusoidal AC and pulsating DC fault currents).

What is the SCCR of the 5SV3444-8?

The short-circuit current rating is 10 kA per IEC 61008-1, with a let-through current of 5,200 A.

Where can I buy the 5SV3444-8 and how is it quoted?

The 5SV3444-8 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
