Product details

Breaking capacity and dual standard rating

The A9P62740 carries two breaking-capacity ratings that govern where it fits: 4.5 kA Icn per EN/IEC 60898-1 for residential or light commercial distribution boards, and 6 kA Icu per EN/IEC 60947-2 for industrial panel applications where the prospective fault current is higher.

D curve — what it means on the line

The D curve trips magnetically between 10 and 14 times the rated current (10–14 x In per EN/IEC 60898-1, with a tighter 12 x In ±20% per EN/IEC 60947-2). If you are protecting a 40 A motor circuit or a control transformer, the D curve is the one that stays closed through the start transient.

The 3P+N body takes 6 module pitches (54 mm wide) on a DIN rail. IP20 finger-safe on the front; IP40 inside a modular enclosure.

Frequently asked questions

What is the breaking capacity of the A9P62740 at 400 V AC?

The A9P62740 is rated 4.5 kA Icn per EN/IEC 60898-1 and 6 kA Icu per EN/IEC 60947-2 at 400 V AC, 50/60 Hz.

What does the D curve mean on this MCB?

The D curve trips magnetically between 10 and 14 times the rated current, making it suitable for loads with high inrush current such as motors and transformers.

What is the width of the A9P62740 in DIN-rail module pitches?

The A9P62740 occupies 6 module pitches (54 mm) on a DIN rail.

Where can I buy the A9P62740?

The A9P62740 is sourced and quoted to order against an RFQ through independent distribution, with availability and current pricing confirmed at quote time.
