What is the operating voltage tolerance, catalog numbers, and clearing times for the Masterpact NT and NW shunt trip and shunt close coils?

Issue:
What is the operating voltage tolerance, catalog numbers, and clearing times for the Masterpact NT and NW shunt trip and shunt close coils?

Product Line:
Masterpact NT NW

Resolution:
Shunt trip: operating threshold is 0.7x to 1.1x Vn (nominal voltage)
Shunt close: operating threshold is 0.85x to 1.1x Vn
Catalog numbers are the same for MX and MN (shunt trip and shunt close) devices; function is determined by placement in the breaker.

MX operating time at Vn:  50 ms ±10 (NW and NT)
XF operating time at Vn:
70 ms ±10 (NW ≤ 4000 A)
80 ms ±10 (NW > 4000 A)
55 ms (NT)

NOTE: Shunt trip (MX) and shunt close (XF) circuits must be energized for a minimum of 200 ms. In other words, don't use an impulse signal. Use a signal of at least 200 ms.
