POWERPACT H/J FRAME MOTOR CIRCUIT PROTECTOR
WITH MANUAL SETTINGS
CHARACTERISTIC TRIP CURVE NO. 045-1
The time-current curve information represents the typical response and is to
be used for application and coordination purposes only.
Curves apply from -30C to +60C ambient temperature.
Notes:
• The MCP is an instantaneous only breaker that detects the peaks of the
current. In order to trip within the specified time-current levels, consecutive
peaks of the current must exceed the selected setting’s threshold.
• Total clearing times shown include the response times of the trip unit, the
circuit breaker opening, and the extinction of the current.
• The time-current curve represents single-phase to three-phase fault currents.
