In Australia and New Zealand, electrical installations must abide by a series of regulations in relation to panelboard construction – e.g. power must be switched off before work on a panelboard can commence (AS/NZS3000:2007). The NHP Grizz-Bar was designed to maintain uninterrupted power to hospitals and data centres whilst complying with these regulations. An innovative advancement of standard power distribution chassis, the Grizz-Bar incorporates a range of unique features to enable compliance with the safe work practices described in AS/NZS3000 whilst maintaining critical power supply. Its proven success has attracted large interest from multinational organisations, opening doors for export opportunities.

  • The interlock mechanism enhances safety by preventing the electrician from accidentally switching the chassis isolator on and powering up a bare connection tag. This is an innovative feature that was it's first of its kind in the market, patent applied for no. 2011202133.

  • A unique and patented lock-off attachment that can be fitted to the chassis ensuring the isolator interlock switch is padlocked open/off for increased safety. Each isolation switch can be locked out using this padlock, which is a commonly adopted work method safety practice. Innovation patent no. 2010100182.

  • The NHP Grizz-Bar achieved the highest ever recorded short circuit withstand results for a device of its type i.e. 25kA unconditional and 63kA conditional rating, in accordance with Australian Standards (AS/NZS3439.1:2002). Once again this is a unique feature to the market.

  • Toggle joining kits convert single phase switches to 2, 3 and 4 pole switches. This ensures multi-phase circuits cannot accidentally have one pole switched. Once again this is a unique feature to the market.

    Circuit breakers are mounted onto the isolation chassis and are not 'live' until the integrated switch is activated. This creates a safer working environment for applications where power is required 24/7.
