NHP Grizz-Bar isolation chassis

NHP has released the Grizz-Bar isolation chassis which has been designed for data centres, hospitals and other applications that require maximum uptime from their power distribution system.

Designed and manufactured in Australia, the chassis has a strong design, with high short circuit current withstand ratings. It has a genuine 250 A rating, tested to AS/NZS 3439.1:2002.

All main busbars are fully encapsulated, including the neutral bar which can be isolated and is fully rated.

The chassis can be fitted with a captive padlock accessory to tag out individual circuits. It has identical dimensions to the CD and NC chassis and, with its comparable I_cw and temperature rise ratings, is a direct replacement for these.

Its multipole attachment bar can convert a single switch toggle into a 2P, 3P or 4P toggle, ensuring multiphase circuits cannot accidentally have one pole switched. The chassis is available as a single end feed or universal feed for total flexibility.

The chassis is suitable for use with standard NHP DIN-T 6, DIN-T 10 MCBs, RCDs, RCBOs and accessories such as DIN-T shunt trips, UVTs, alarms and auxiliary switches.
