Product details

The Siemens SENTRON 5SV4646-0 is a 4-pole residual current circuit breaker (RCCB), Type AC, rated 63 A with a 300 mA sensitivity and 400 V AC supply. Mounts on DIN rail (REG) and fits into a 4-module-width grid (60 mm spacing).

The 300 mA sensitivity is sized for equipment protection (fire prevention) rather than personal shock protection, which typically requires 30 mA or lower. The 63 A continuous rating matches the upstream feed; verify that the load current stays under this at 400 V three-phase. Rated for 50 Hz only (not 50/60 Hz), so confirm the line frequency matches before specifying.

The 70 mm depth matches the typical SENTRON RCCB/MCB family, so it sits flush in a distribution board alongside 5SL or 5SY breakers. The IP20 rating applies only when the distribution board is installed with connected conductors; plan for proper enclosure sealing if the board is in a dusty or wet area.

Frequently asked questions

Where can I buy 5SV4646-0 and get current pricing?

The 5SV4646-0 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

Will 5SV4646-0 drop into a panel designed for 5SL4363-7 without rewiring?

Not without panel layout adjustment. The 5SV4646-0 is 72 mm wide (4 module widths) versus 54 mm (3 modules) for the 5SL4363-7, so it needs one extra module space. The DIN-rail mounting and 70 mm depth are the same; no rewiring of the load side is required if the feed is 4-pole.

What is the depth of 5SV4646-0?

The depth is 70 mm, matching the standard SENTRON RCCB/MCB family depth.

What compliance documentation does Siemens provide for 5SV4646-0?

The product carries a silicon-free designation and is designed per IEC 61008-1. The manufacturer typically provides RoHS, REACH, and CE declarations; specific documentation is available upon request with an RFQ.
