Compact Merlin Gerin Two-poles NS100/160/N/H

Presentation

The new Compact NS range achieves a significant technical advance in the evolution of moulded-case circuit breakers. Compact NS circuit breakers offer users a long term safety, and the best probability of continuing energy supply and convenience of operation: c compliance with most standards and agreements worldwide, c service breaking capacity Ics = 100 % Icu (according to IEC 947-2), c suitability for isolation with positive break indication, c on request, numerous functions for indication, measurement and control.

Suitability for isolation and safety of personnel

All Compact circuit breakers are suitable for isolation as defined in IEC standard 947-2. The operating handle cannot indicate the "off" position unless the contacts are actually open. For protection against direct contact with live parts, Compact circuit breakers may be installed through the front panel of Class II switchboards (as per IEC 664).
