Product details

It breaks faults up to 6 kA per EN 60898 and IEC 60947-2 at 400 V AC, and handles up to 60 V DC per pole.

Mounting & Integration

This MCB snaps onto a standard DIN rail, occupies 2 width units (36 mm), and accepts conductors from 0.75 to 25 mm² solid or stranded. Rated IP20 with conductors connected, so it belongs inside a sealed enclosure, not out in the open.

Environmental & Compliance

Energy limiting class 3 offers good current-limiting performance to reduce let-through energy on downstream equipment. The sealable feature allows panel builders to lock the toggle position to prevent unauthorized switching.

Frequently asked questions

Where can I buy the 5SJ6220-7KS and how is it quoted?

This part is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time — submit an RFQ for the latest position.

What is the breaking capacity of the 5SJ6220-7KS?

It has a 6 kA breaking capacity per both EN 60898 and IEC 60947-2 at 400 V AC. At 60 V DC the breaking capacity follows the manufacturer's DC derating curve.

What wire sizes does the 5SJ6220-7KS accept?

Terminals accept 0.75 to 25 mm² solid or stranded copper conductors. The spring-cage or screw terminals (depending on variant) grip firmly without damaging strands.
