Product details

It is rated for distribution duty and carries a 70 kA Icu at 380/415 V AC 50/60 Hz per EN/IEC 60947-2, with the breaking capacity curve extending from 100 kA at 220/240 V down to 10 kA at 660/690 V. The thermal-magnetic trip provides L (overload, thermal) and I (short-circuit, magnetic) protection, with the neutral protection set to 1 x Ir (4D). This is a current-production part.

The 4-pole configuration with neutral left and 1 x Ir neutral protection suits TN and TT systems where full neutral protection is specified.

Durability and environmental rating

Mechanical endurance is 20,000 cycles; electrical endurance at 440 V In is 10,000 cycles, halved at 690 V In. That is typical for a distribution MCCB — adequate for a main or feeder breaker that operates infrequently, not for a motor-switching role. The IP40 enclosure protection and IK07 impact resistance (IEC 62262) suit indoor panel installation where dust ingress is limited. Operating altitude is 0–2000 m without derating, with derating required above that.

Overvoltage category III and utilisation category A confirm its place in fixed-installation distribution boards. The 86 mm depth and 161 mm height fit standard NSX cutouts; the 140 mm width for the 4P version is wider than the 3P variant — verify panel door clearance before specifying.

Frequently asked questions
