Figure 3 & 4 Notes:

1. Output currents are defined in the Must Trip / May Trip / Must Not Trip regions. Load fault current in the “ON” operating

condition is limited by the source and load impedance.

2. Over current and fault trip currents terminate abruptly and may require external “snubbing” or clamping to prevent damage

to the IPC.
