It carries 50 A at 40 °C, derating to 45 A at 70 °C. Breaking capacity is the headline: 52.5 kA at 240 V, 32 kA at 415 V, and still 7.5 kA at 690 V. The 690 V rating is enough for most 600 V class North American panels.
Built-in shunt trip (STL) and two HQ auxiliary switches allow remote tripping and status feedback without an add-on module.
Yes, it is equipped with a shunt trip (STL) for remote tripping, plus two HQ auxiliary switches for status indication.
