Specs At A Glance

Good To Know

Q: How do I know this solenoid will fit my machine? A: Verify that your starter circuit uses a 4-terminal configuration and a 14V control signal, and compare your original part number to the 784-1421-020 cross-reference for a direct match.

Q: Can this contactor handle repeated starting cycles? A: Yes, the heavy-duty contacts and sealed construction are designed to withstand frequent use in daily starting operations, though extreme electrical loads may shorten service life.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
