FOTEK HPR-100AA-H 100A AC Solid State Relay SSR | Industrial

FOTEK HPR-100AA-H Solid State Relay (100A AC/AC)

Upgrade your industrial or automation control system with the FOTEK HPR-100AA-H Solid State Relay (SSR). Designed for high-current AC load switching, this 100-amp solid state relay delivers reliable, silent, and spark-free switching — making it an excellent choice for industrial machinery, heating control systems, motor control panels, and automation equipment.

Unlike traditional mechanical relays, solid state relays have no moving parts, which means longer service life, faster switching speeds, and reduced electromagnetic interference in your system. The HPR-100AA-H is a direct-fit replacement or compatible part for FOTEK Yangming SSR applications.

Frequently Asked Questions

Q: What does "AA" mean in the FOTEK HPR-100AA-H model designation?

A: The "AA" in the model number indicates that this is an AC input to AC output solid state relay. It accepts an AC control signal and switches an AC load — making it suitable for standard industrial AC power control applications.

Q: Is the HPR-100AA-H a direct replacement for my existing FOTEK SSR?

A: Yes, the FOTEK HPR-100AA-H is designed as a direct-fit replacement for compatible FOTEK Yangming HPR series solid state relays. Always verify your existing relay's input voltage, output voltage, and current rating before installation to ensure compatibility.

Q: Does a solid state relay require a heat sink?

A: For high-current applications such as this 100A relay, mounting on an appropriate heat sink is strongly recommended to dissipate heat and maintain reliable long-term operation. Refer to the manufacturer's datasheet for thermal management guidelines.

Q: What are the advantages of a solid state relay over a mechanical relay?

A: Solid state relays offer several advantages: no moving parts (longer lifespan), silent operation, no arcing or sparking, faster switching speeds, and reduced electromagnetic interference — all of which make them ideal for precision industrial control systems.
