Molded Case Circuit Breaker NSX is innovative, it incorporates monitoring and communication functions, from 40A upward, combined with impeccable protetion.

Exper Technology, a roto-active contact breaking principle provides limitation and endurance performance:

■Very high breaking capacity in a very small device;

■Exceptional fault current limitation for extended system life;

Reduced Installation Costs, achieve up to 30% savings:

■Total discrimination is ensured particularly in the case of miniature circuit breakers for considerable savings at the time of installation;

■Smaller devices mean more economical swtichboards for a significant impact on overall cost of installation, no need for over calibration;

New Breaking Capacities, new performance levels improve application targeting:

■25kA-Standard low short circuit level applications in service business;

■36kA-Standard applications such as industrial plants, buildings and hospitals;
