The shunt trip release (STL) is built in, so remote tripping via a pushbutton or safety relay is ready out of the box.
Above that, it derates linearly: 60.6 A at 55 °C, 58.3 A at 60 °C, 55.9 A at 65 °C, and 53.6 A at 70 °C (–). For a panel OEM stuffing this into a 105 mm wide × 181 mm high × 86 mm deep (–) enclosure, the derating curve means you can push the full 63 A up to 50 °C ambient — common in ventilated industrial panels — but need to account for the drop in sealed, high-temp cabinets. The 4 W maximum power loss is modest; heat dissipation won't drive fan sizing on its own.
The line and load terminals accept copper or aluminum conductors up to the manufacturer's specified lug range; the integrated shunt trip (STL) wiring lands on the auxiliary terminal block, keeping control wiring separate from the power path. The trip indicator gives a visual red flag when the breaker has tripped on fault, not just been switched off — useful for field service techs troubleshooting a downstream short.
