Hager Invicta3 Isolator Incomer Kit 250A 3 Pole JN223BS

Hager JN223BS: 250A 3 Pole Isolator Incomer Kit with non-automatic MCCB switching for distribution board incomers.

Safe, Reliable Isolation

This kit gives you a dedicated non-automatic MCCB isolator for the incoming supply to your distribution board, so the whole board can be safely disconnected before any maintenance or fault-finding work begins. Because it's a manual isolator rather than an automatic breaker, switching is deliberate and controlled, reducing the risk of unexpected trips during normal operation.

Heavy-Duty 250A, 3-Phase Capacity

Rated at 250A across 3 poles, this incomer kit is built for commercial and industrial distribution boards carrying substantial load. The 3-phase configuration suits larger installations where single-phase isolators simply aren't enough, giving contractors a dependable point of isolation ahead of downstream protective devices.

Installation & Compliance

Designed as a factory-matched incomer kit for Hager distribution boards, this unit installs cleanly into the board's incoming section without the need for bespoke adaptation, saving time on site. It's part of the wider Hager Ltd distribution board range, which also includes AFDD-equipped boards for added arc fault protection, so contractors can specify a consistent Hager electrical solution across an installation. Always verify final wiring against BS 7671 requirements for isolation and switching arrangements.
