Its interrupting capacity reaches 242 kA at 240 V AC, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V — the 240 V figure governs the worst-case fault clearing for most low-voltage commercial and industrial services, so the breaker safely interrupts a bolted fault at that level without cascading upstream. The unit carries a ground-fault monitoring function using summation current formation on L + N conductors, and includes both communication and other measurement functions — meaning it can report status and fault data to a higher-level control system without an add-on module.
The 4-pole form factor occupies four module spaces; verify gland-plate clearance for the 86 mm depth when retrofitting into existing enclosures. Maximum power loss is 2.2 W, so thermal rise within a sealed panel stays manageable without forced ventilation.
