3 MODbreak and MODpower Your economical Power Distribution Solution NHP are proud to introduce the new MOD series range of economical power distribution Moulded Case Circuit Breakers (MCCBs) and Air Circuit Breakers (ACBs). The MODbreak and MODpower family of products offer a complete range of circuit breakers from 20 to 3200 amps and are ideally suited to the commercial building market as well as contractors and mechanical services. The MOD series includes a complete suite of accessories to complement the range including remote operation, safety shrouds, off position padlocking and much more. Ensuring free and easy selectivity software for use with the MOD series range, NHP has also developed MODcurve. This software enables customers to make informed decisions regarding the electrical protection of their installation from product selection through to trip settings. The MOD series also empowers users to upgrade their circuit breakers to suit their requirements thanks to the design that offers increased flexibility and easy customer fit accessories.

This ensures faster tripping for current limiting. The result-very low let-through, cut-off current and fault clearing time Mechanical anti-reclosing This unique feature ensures that under short circuit conditions, the contacts open and latch even before the release gives a trip command to the mechanism. This avoids contact re-closing and bounce Low watts loss The entire current carrying path is designed to achieve a very low watt loss Positive isolation The MCCB toggle indicates the true position of the main switching contacts Double insulation Internal accessories are housed in insulated casings to ensure a first level of insulation. When the front cover is opened for the fixing of internal accessories, the MCCB is totally insulated ensuring double insulation. Forward or reverse connection MODbreak MCCBs can be forward or reverse connected to allow reversal of line and load connections. This is especially important for MB and MBC chassis where MODbreak MCCBs are reverse connected on the chassis as standard. 5
