Its interrupting capacity hits 330 kA at 240 V and still delivers 242 kA at 415 V and 440 V, dropping to 187 kA at 500 V and 3 kA at 690 V — the high-end short-circuit ratings mean this breaker can be placed at the service entrance or on a high-fault bus without worrying about cascading failure upstream.
Front face carries IP40 protection.
Communication and auxiliary functions
The breaker supports communication functions. It ships without an undervoltage release, without a voltage trigger, and without ground-fault monitoring — those are add-on options if the application requires shunt trip or GF protection. Maximum power loss is 1.2 W at rated load, negligible for panel thermal budgeting.
