FAQ
What are the two types of solid state relays?
- Zero-crossing relays: Activates when the AC voltage crosses zero.
- Random turn-on relays: Triggered at any point in the AC cycle.
What current does a solid state relay control?
- MSD 7564-HC manages up to 20 amps of current effortlessly.
- It reliably controls varying current loads for optimal performance.
What is a solid state over current relay?
- The MSD 7564 is an over current relay safeguarding against excessive electrical flow.
- Monitors and prevents high current, ensuring system safety.
What is the difference between SSR and mechanical relay?
- MSD solid state relays (SSRs) like the 7564-HC use semiconductors for switching, offering faster response and longer lifespan.
- Unlike mechanical relays, they have no moving parts, reducing wear and tear.

Motor Vehicles
WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.
Tools:
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
Electrical Cords
WARNING: The wires of these products contain chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Wash hands after handling.
