Rated In=630A with overload protection adjustable Ir=250A...630A and short-circuit protection Isd=0.6..9x In, Ii=1.5..9x In, it delivers a breaking capacity Icu=55kA at 415V AC — class M.
Deployment Context
The built-in shunt trip (left side, 208-277V AC 50/60 Hz or 220-250V DC) allows remote tripping for emergency-stop or interlock circuits — verify coil voltage matches your control supply before wiring.
