Product details

The Siemens 5SL6220-7 is a SENTRON 2-pole miniature circuit breaker rated 20 A with a C tripping characteristic and 6 kA breaking capacity per both EN 60898 and IEC 60947-2. This is the part you spec into a residential or light-commercial distribution board where the branch circuit needs overcurrent and short-circuit protection on a 400 V AC three-phase system.

Snaps onto standard DIN rail; mounting position any.

In a residential or light-commercial main distribution board with a typical upstream transformer impedance, that covers the majority of installation scenarios. The 2-pole design switches both phase and neutral — required for single-phase branch circuits where the neutral is switched. Sealable terminals (yes) allow a lockout-tagout seal across the screw terminals for isolation verification.

Frequently asked questions

What is the breaking capacity of 5SL6220-7?

6 kA per both EN 60898 and IEC 60947-2 at 400 V AC. That's the standard breaking capacity for residential and light-commercial distribution boards.

What is the width of 5SL6220-7?

36 mm, which is 2 modular width units on a standard DIN rail. Depth is 76 mm, installation depth 70 mm.

Where can I buy 5SL6220-7 and how is it quoted?
