Breaking capacity is the headline here: 242 kA at 240 V, 187 kA at 415/440 V, 121 kA at 500 V, and 3.7 kA at 690 V. Width and height are standard for this frame size; it'll drop into a 3-pole SENTRON mounting base without panel rework.
Integration and auxiliaries
That's a safety feature for machinery where loss of control power should kill the load, not leave it live. That's enough for a PLC to know whether the breaker is open manually or tripped on a fault. Rated as line protection, not motor protection — there's no adjustable overload curve for a motor start. Use it for feeder, distribution, or backup protection where the load is a bus or a group of downstream devices. Maximum power loss is 28 W at rated current, which is modest for a 160 A frame; it won't cook the neighboring devices in a dense DIN-rail layout.
