It's rated 50 A continuously at 40 °C (derating to 45 A at 70 °C), with an insulation voltage of 800 V. Interrupting capacity is the headline number here: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. That's enough to handle high-fault utility feeds or transformer secondaries — the 121 kA figure at 240 V covers most North American panelboard applications, while the 75.6 kA at 415 V suits European industrial distribution.
Auxiliary configuration and panel fit
Physical footprint: 76.2 mm wide (3 in), 130 mm tall, 70 mm deep. Power loss is 14.6 W maximum at rated current — relevant for thermal management inside a sealed enclosure.
