Product details

At 6 A, that's a magnetic trip between 30 A and 60 A. The 1P+N layout saves one width unit versus a 2-pole breaker on a 4-wire system — two width units total, leaving more rail space for other circuits.

Panel integration

Snap-on DIN rail mount, 2 width units (about 36 mm). IP20 finger-safe terminals. The switched neutral (product function / neutral conductor switching = Yes) means the neutral is disconnected when the breaker is off or trips — important for isolation during panel servicing. Overvoltage category 3 and energy limiting class 3 are standard for distribution board use.

Frequently asked questions

What is the 5SQ2570-0KA06 used for?

It's a 2-pole 1P+N miniature circuit breaker rated 6 A, C-curve, with a 3 kA breaking capacity per EN 60898. Used for branch circuit protection in 240 VAC panels where the neutral needs to be switched along with the phase.

What does 1P+N mean on this breaker?

1P+N means one pole provides overcurrent protection (the phase) while the second pole switches the neutral without protection. This saves one width unit compared to a full 2-pole protected breaker.

Where can I buy the 5SQ2570-0KA06?

This part is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time — no stock figures are carried on this listing.
