It carries a 187 kA interrupting capacity at 240 V, dropping to 121 kA at 415 V and 440 V, then to 75.6 kA at 500 V, and 3.7 kA at 690 V — so the available fault current at your service voltage is the deciding factor for whether this breaker clears without upstream coordination issues.
Interrupting Capacity and Selectivity Planning
At 240 V the 187 kA SCCR is high enough for most service-entrance and large subfeed applications. At 415/440 V the 121 kA rating still covers heavy industrial fault levels. The drop to 75.6 kA at 500 V and 3.7 kA at 690 V means this breaker is not suited for 690 V main feeders with high fault current — for that voltage class you would step up to a higher-rated frame. The 100 A continuous rating is flat across the temperature range, so no thermal derating tables are needed for panel design.
Physical Fit and Auxiliary Configuration
A communication function is built in, enabling integration with energy management or SCADA systems. Maximum power dissipation is 10 W at rated load, which is modest for a 100 A frame — panel ventilation requirements are minimal.
