Are the Masterpact NW and NT shunt trip and shunt close coils continuous-duty rated?
Does the Masterpact NW shunt trip and shunt close have a coil clearing switch?
Masterpact NT and NW breakers
Yes, the coils themselves are continuous duty rated and do not use a coil clearing switch. However in actual use, a maintained signal should not be used on the shunt close coil (XF). Any opening order will open the breaker so a standing close order is not necessary (see Anti-Pump Feature in the Masterpact catalog 0613CT0001). Instead, use a signal of at least 200ms on the shunt close coil (XF), then remove the signal.
