Continuous-Duty SPST Series Solenoid Relays are designed with single-pole, single-throw (SPST) circuitry and come in a wide variety of configurations to meet the electrical and environmental requirements of various applications.
With continuous current ratings of 65 A, 85 A, 110 A, or 200 A and a range of coil voltages available, the Continuous-Duty SPST series makes it simple to find the right heavy-duty solenoid relay for high current loads.
Select models of Continuous-Duty SPST series solenoid relays come with a PVC coating, which seals the relay to withstand moisture and dust to an IP66 rating.
In addition, select models are available with a potted interior, which provides added protection for the coil and studs. These models are ideal for applications where vehicle vibration is an issue.
- Configurations with 6 V, 12 V, 24 V, or 36 V coil ratings are available
- Models are available with a 65 A, 85 A, 110 A, or 200 A continuous current rating for handling high current loads
- Insulated and grounded options allow you to match the requirements of your application
- SPST or latched SPST circuitry, depending on the model
- Large 5/16"-24 copper power studs and small #10-32 steel coil studs (for the control circuit) are heavy and durable
- Plated steel housing with PVC-coated options available for applications requiring a sealed solenoid to withstand moisture and dust to an IP66 rating
- Potted interior on select models offers vibration resistance
