Stud-Terminal Relays

12VA Control Power

9VA Control Power
These relays are suitable for DC-powered equipment such as forklifts, floor scrubbers, and trucks. They are rated for continuous operation for cycles that run longer than 30 seconds.
3-terminal relays require the same input and switching voltage. 4- and 6-terminal relays allow different input and switching voltages.
