ABB ZP1650-70 Contact Coil Circuit Board

Core Performance & Industrial Application

The ABB ZP1650-70 (1SFN166521R1070) is a printed circuit board designed for the AC/DC wide-range operating coil of heavy-duty block contactors.

It supplies and drives the contactor coil over a broad 100-250V AC/DC supply range, ensuring reliable pull-in under fluctuating grid voltage.

It is fitted inside the contactor body as an internal coil drive PCB and serves as a direct replacement spare for coil circuit failure.

The board adopts industrial-grade electronic components with over-current and surge protection, suitable for long-term continuous switching duty.

It is widely used as spare replacement for large motor control contactors in industrial switchgear cabinets.
