It is rated 160 A continuous (In) with fixed overload protection at Ir = 160 A and fixed short-circuit pickup at Ii = 10 × In.
Protection and Accessories
The breaker ships with a shunt trip (STL) rated 12–30 V DC or 24 V AC 50/60 Hz, plus two HQ auxiliary switches for remote status. The neutral conductor is unprotected (no integral neutral protection) — common on 4-pole breakers where the neutral is switched but not monitored. Connection is via clamp terminals, which accept copper or aluminium conductors without lugs.
