The '30' in the order code indicates three main poles normally open; the '01' indicates one auxiliary contact normally closed. The '-80' suffix denotes the coil voltage — typically 220-230 V 50/60 Hz or 240 V 60 Hz for this suffix, though the exact coil rating should be verified against the original BOM.
Deployment Context
Its 3-pole configuration handles three-phase motor circuits up to the A26 frame rating — typically 26 A in AC-3 duty for standard induction motors on pumps, fans, and conveyors.
