Product details

The neutral conductor is switched internally, so this single module handles both phase and neutral protection in a 2-pole format.

The 2-pole design with neutral switching makes this a 2-module-width unit — it occupies two DIN-rail spaces in the enclosure.

Panel integration

IP20 finger-safe protection is typical for enclosed panel mounting — no additional shrouding needed inside a closed cabinet. Overvoltage category 3 confirms suitability for fixed installations with transient overvoltages up to 4 kV phase-to-earth.

Frequently asked questions

What is the breaking capacity of 5SQ2270-2YA04?

The breaking capacity is 3 kA per EN 60898 at 400 V AC. This is the maximum fault current the MCB can safely interrupt under standard test conditions.

Where can I buy 5SQ2270-2YA04?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

Will 5SQ2270-2YA04 drop into a panel specified around 5SQ2570-2YA04?

Yes — both are 2-pole, 4 A, C-curve MCBs with identical installation depth (55 mm) and IP20 rating. The 5SQ2570-2YA04 shares the same electrical ratings and physical footprint, so no rewiring or panel modification is needed for a direct swap.
