The A30-30-10 230-240V 50HZ: For a BOM line that requires this exact order code, sourcing runs through independent distribution. No official successor order code is on record; a form-fit-function substitute would need to be evaluated against the original application's coil voltage (230-240V 50Hz) and contact configuration (3 NO + 1 NC).
The order code encodes the contact arrangement (3 normally-open main poles, 1 normally-open auxiliary) and the coil rating (230-240 VAC, 50 Hz).
Deployment Context
This contactor mounts to a DIN rail or panel base within an enclosure, wired between the supply and the load. The 230-240V 50Hz coil is standard for European industrial mains; verify the control circuit voltage matches before installation.
