It carries a continuous current rating of 50 A at 40 °C, derating to 45 A at 70 °C, so the thermal curve is what governs the real ampacity in a warm enclosure — don't size it at 50 A if the ambient inside the panel runs above 55 °C. The breaking capacity hits 52.5 kA at 240 V and 32 kA at 415 V, which covers most industrial service-entrance and feeder applications where fault currents are high.
Shunt trip and overcurrent release
Verify the busbar or lug kit spacing against the existing panel layout — the shunt trip adds no extra width, but the wiring for the STL control signal needs a separate pair of terminals.
Maximum power loss is 14.6 W at rated current. In a densely packed panel, that heat needs to be considered for the enclosure's thermal budget — especially if the breaker is mounted next to other heat-generating devices.
