Low-Voltage Power Circuit Breakers Conversion Kits with Enhanced MicroVersaTrip PlusTM or MicroVersaTrip PMTM Digital RMS Trip Units Long-Time Delay, Short-Time Delay, and Instantaneous Time-Current Curves Curves apply at 50 to 400 Hertz and from -20°C to 55°C Breaker ambient. Note: Operation above 60 Hertz requires thermal and interrupting derating of the circuit breaker.
