Molded case circuit breaker The new COMPACT NS line achieves a significant technical advance in the evolution of molded case circuit breakers. These circuit breakers use an entirely new technology in current interruption. Short-circuit protection is enhanced by a unique double rotating break (dual break system) which brings an exceptional current limitation and outstanding endurance on repetitive short-circuit interruptions. COMPACT NS circuit breakers offer a continuous energy supply and convenience of operation: ■ Compliance with most standards and agreements worldwide. ■ Suitability for isolation with positive break indication. ■ On request, numerous functions for indication, measurement and control available. ■ Moisture and fungus protection. ■ Reinforced insulation. ■ Snap-in field-installable accessories. ■ Reverse feeding. ■ Maintenance-free operation.
