Product details

The 5SV5646-6KL: Type A detection covers sinusoidal AC residual currents plus pulsating DC. The 300 mA trip threshold is typical for fire protection or general shock prevention in industrial sub-distribution.

Depth is 70 mm, width 72 mm, height 90 mm — the 4-module footprint matches the SENTRON family. Supply can enter from top or bottom. IP20 rating applies once the distribution board is installed with conductors connected; the device itself is not sealed for wet environments.

Frequently asked questions

What is the 5SV5646-6KL used for?

It is a 4-pole residual current circuit breaker (RCCB) for 400 V AC systems, rated 63 A with a 300 mA type A trip. It protects against ground faults in industrial sub-distribution panels, typically on DIN-rail mounted boards.

What are the key dimensions — depth and width?

Depth is 70 mm, width is 72 mm, height is 90 mm. It occupies 4 modular width units on a DIN rail.
