Its 63 A continuous rating holds flat from 40 °C through 70 °C (no derating needed across that band), and the adjustable trip class (10A, 10E, 20E) lets you match the thermal curve to the motor start profile.
The interrupting ratings span the common industrial voltages: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. At 415 V, that 121 kA SCCR gives you headroom for high-fault panels without cascading upstream — useful when the transformer is close to the switchboard.
Maximum power loss is 4 W, so heat buildup inside a sealed enclosure stays manageable.
