Isobar 4

Miniature circuit breaker distribution boards

The Isobar range allows for hundreds of Distribution board combinations and can be assembled from just a few modules. Isobar 4c modules can be joined at the top, bottom or sides to make assemblies that cater for the biggest or most complex installations.

The standard range includes three-phase 250A boards with up to 24 outgoing ways and single-phase 125A boards with up to 23 outgoing ways.

Split-load / multi-service configurations are available as part of the standard range and all units are compatible with incoming disconnectors RCCBs and MCCBs. Compatability also extends across the C60H ranges of MCBs and RCBOs for the protection of outgoing circuits.

All versions of Isobar incorporate the unique busbar connection device, which allows for a quick connection and unused ways are isolated.

Powerpact 4

Moulded Case Circuit Breaker Distribution boards

The market leading low voltage distribution products offer, provides many unique features in the field of low voltage electrical distribution. The Powerpact 4 MCCB panel board range gives the ability to provide a switched neutral and add earth fault protection.

This can be added to any incomer or outgoer at installation should the need arise. Ratings covered are from 250A up to 1600Amp. Protection for incoming and outgoing devices is provided by the Compact NS range of Mccb’s specifically adapted for Powerpact.
