It has no built-in suppressor module, so external suppression (RC snubber or varistor) must be added across the coil terminals if the application requires it — common practice for PLC-driven contactors or when switching inductive loads near sensitive electronics.
The coil will pull in reliably at 85–110% of rated voltage per IEC 60947-4-1, but the 660 V rating is specific to 50/60 Hz supplies; it is not suitable for DC control circuits.
This part is listed as obsolete by the manufacturer. No official successor order code appears in the available records. If your customer's AVL requires a current-production part, a deviation or approved alternate will be needed; the TeSys range includes newer coil variants, but pin-to-pin compatibility and mounting footprint must be verified against the specific contactor frame.
