Product details

The Siemens 5SV4346-0 is a SENTRON residual current circuit breaker (RCCB), 4-pole, Type AC, rated 63 A with 30 mA sensitivity on a 400 V AC, 50 Hz supply.

Depth is 70 mm, height 90 mm. Grid spacing is 60 mm — standard for European distribution boards. Supply can land top or bottom. The IP20 rating is conditional on the distribution board being installed with conductors connected — expected for a panel-mount device.

Short-circuit and coordination

Rated short-circuit current is 10 kA per IEC 61008-1, with a permissible series fuse short-circuit current of 100 A. The rated impulse withstand voltage (overvoltage category III) suits fixed-installation downstream of the main panel.

Thermal and environmental limits

Silicon-free construction, which matters for potting or conformal-coating compatibility in sensitive electronics environments.

Frequently asked questions

Where can I buy 5SV4346-0 and get a price?

The 5SV4346-0 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the depth of 5SV4346-0?

The depth is 70 mm.

What is the width of 5SV4346-0?

The width is 72 mm, which corresponds to 4 modular width units.

Will 5SV4346-0 drop into a panel specified around 5SL4363-7?

Not without rewiring. The 5SL4363-7 is a 3-pole miniature circuit breaker (MCB) 54 mm wide, while the 5SV4346-0 is a 4-pole RCCB 72 mm wide. They serve different functions — overcurrent vs. earth fault protection — and occupy different panel footprints.

What compliance documentation does Siemens provide for 5SV4346-0?

The device is designed according to IEC 61008-1 and carries an overvoltage category III rating. Specific RoHS, REACH, and UL documentation should be confirmed at quote time from the distributor.
