Compact C801 1251 051166 Compact NS250H Electronic trip unit STR35SE Electronic trip units allow perfect adaptation of the protection to each circuit in the electrical distribution network, and, at the same time, simplify the selection, installation and operation of the devices: c wider range of settings, so that a single trip unit can provide several types of protection, c easier checking during assembly or on site, c new functions offered by the trip unit, such as load monitoring and local indications Compact C1251H circuit breaker Merlin Gerin 045212 other functions indication and

Compact NS100 to C1251 circuit breakers Remote control of the opening, closing and reset functions is then possible via or impulse or maintained signals If necessary, the circuit breakers can still be operated locally via the controls on the front face The motor mechanism modules for each range have a common size The motor mechanism module for Compact NS is also available in communicating version (see Digipact catalogue) Vigi modules can be added to Compact NS circuit breakers to provide earth-fault protection The Vigi modules fit directly on the circuit breaker terminals The addition of a Vigi module has no effect on the other performance characteristics of the circuit breaker 044333 Vigi earth-fault protection module c auxiliary switches: v Compact NS: just one model, the same for all Compact NS80 to NS630 and NSA125/ 160 circuit breakers, provides four different functions (OF, SD, SDE and SDV) depending on where it is fitted in the circuit breaker, v Compact C: two models, the same for all Compact C801 to C1251 circuit breakers, provide remote indications of circuit breaker status and electrical faults (e.g 30F + 1SD), c the MN or MX voltage releases are common for all models within each of following ranges: v NS80 and NSA125/160, v NS100 to NS630, v C801 to C1251 c auxiliary switches for Compact NS are also available in communicating version and can be installed in
