Manual Protection Settings
The manual settings may be adjusted to multiples of current based on the rotary switch setting for
motor Full Load Amps (FLA).
For example, if FLA rotary switch is set to 20 and I
m
rotary switch is set to 9x, then the instantaneous
trip point will be 180 A.
See Tables 55 thru 57 for more information.

High Short Circuit Current Ratings (SCCR)
The PowerPact MCP helps achieve the high UL508A Short Circuit Current Rating (SCCR) needed
to meet NEC Article 409 requirements for industrial control panels. They deliver up to 100 kA at
480 Vac SCCR when used in combination with approved Square D™ NEMA or Schneider
Electric™ IEC motor starters.
