Product details

It's a 3-pole, 32 A thermal-magnetic (TM-D) unit rated for distribution duty in commercial and industrial panelboards. Mounts to a backplate with front-facing connections; IP40 enclosure rating and IK07 impact resistance suit it for general indoor panel use, not washdown environments.

Breaking capacity and what it means for your fault current

Rated 40 kA Icu at 240 V AC and 25 kA Icu at 415 V AC per EN/IEC 60947-2. For a 32 A feeder in a 415 V distribution board, 25 kA covers most secondary-side transformer faults in commercial buildings. The 3D protected poles description means all three poles have full thermal-magnetic protection — no unprotected neutral.

Mechanical endurance of 50,000 cycles and electrical endurance of 50,000 cycles at 440 V at half rated current (In/2). At full rated current (32 A at 440 V) that drops to 30,000 cycles — still well above the typical life of a distribution breaker in a fixed panel. The suitability-for-isolation mark per EN/IEC 60947-2 means you can use this as a visible-break disconnect for safe maintenance, provided the load side is de-energized.

Frequently asked questions
