Specs At A Glance

Good To Know

Q: Will this relay work with a continuous duty cycle? A: Yes, the relay is rated for continuous operation under typical electrical loads, though verify current draw against the contact rating.

Q: Can this replace a magnetic switch with different terminal spacing? A: Standard post spacing matches common Prestolite and aftermarket housings, but measure your existing unit to confirm geometry.

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