MICROLOGIC™ ELECTRONIC TRIP UNITS
Micrologic™ 2.2M Overload Trip Curve
30A, 50A, 100A, 150A H-Frame, 250A J-Frame
The time-current curve information is to be used
for application and coordination purposes only.
Notes:
1. If overload still exists past overload relay delay,
MCP will open 0.4 seconds later.
2. Total clearing times shown include the
response times of the trip unit, the circuit
breaker opening, and the extinction of the
current.
3. Isd minimum and maximum only shown.
4. li = 15 x In
In = 30A, 50A, 100A, 150A, 250A
MCP will trip <30ms at 15 x In
Curves apply from -35ºC to +70ºC (-31ºF to
+158ºF) ambient temperature.
