Product details

What you're looking at

The Schneider Electric A9K23250 is a 2-pole Acti9 iK60N miniature circuit-breaker rated at 50 A with a B-curve trip characteristic. Thermal-magnetic trip means it handles overloads (thermal bimetal) and short-circuits (magnetic coil) in one package.

The B-curve (magnetic trip 3...5 x In) means this MCB trips magnetically between 150 A and 250 A. It is NOT for motor starts or transformer primaries where a C or D curve would be needed to ride through the inrush.

Panel integration

Clip-on DIN-rail mount, 36 mm wide (4 modules). Terminals accept 1...35 mm² rigid wire; strip 14 mm and torque to 3.5 N.m. IP20 finger-safe front. Padlocking device available for lockout/tagout. No earth-leakage protection built in — that's a separate RCD if needed. The ON/OFF toggle gives local indication; there's no remote contact-position indicator.

Frequently asked questions

What is the breaking capacity of A9K23250?

6,000 A Icn at 400 V AC 50/60 Hz, conforming to EN/IEC 60898-1. That's the standard fault level for a final-circuit MCB in most residential and light commercial boards.

What is the B-curve magnetic trip range?

The magnetic trip operates at 3 to 5 times the rated current (In). For this 50 A MCB, that means instantaneous trip between 150 A and 250 A.

Where can I buy A9K23250?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What compliance standards does A9K23250 meet?

It conforms to EN/IEC 60898-1 for miniature circuit-breakers. Pollution degree 2, overvoltage category III, and suitability for isolation per that standard. IP20 front protection.
