Hager JF444BS Isolator Incomer Kit 4 Pole 400A

Hager JF444BS: 400A 4 Pole Isolator Incomer Kit with M12 lug for 400A distribution panelboards.

Safety & Reliability

This isolator incomer kit gives you a dedicated main switch point for 400A distribution boards, so you can isolate the entire installation safely before working on downstream circuits. The 4 pole configuration covers three-phase and neutral switching in one unit, cutting down on additional isolation hardware.

Installation & Compliance

The M12 lug terminates heavy-gauge incoming cable securely, reducing the risk of loose connections on high-current supplies. As a genuine Hager Ltd component, it's designed to integrate directly with Hager 400A panelboard systems, so installers avoid compatibility issues and rework on site.

Durable Construction

The plastic housing with cover protects live parts from accidental contact and keeps dust and debris out of the switching mechanism. This is a straightforward, no-frills incomer kit built for commercial and industrial distribution boards where dependable isolation matters more than extras.
