FOTEK ESR-60DA Three-Phase Solid State Relay Module 60A

FOTEK ESR-60DA High-Power Three-Phase Solid State Relay Module

Upgrade your industrial control setup with the FOTEK / Yangming ESR-60DA High-Power Three-Phase Solid State Relay (SSR) Module. Engineered for demanding three-phase switching applications, this solid state module delivers reliable, silent, and spark-free operation — making it an essential component for industrial machinery, heating control systems, motor drives, and automation panels.

Unlike traditional electromechanical relays, solid state relays have no moving parts, which means reduced wear, longer service life, and faster switching response. The ESR-60DA is built for high-current three-phase loads, making it a trusted choice for engineers and technicians who require precision and durability in their electrical control circuits.

What Is a Solid State Relay?

A solid state relay (SSR) is an electronic switching device that switches power to a load when a small external voltage is applied. With no mechanical contacts, SSRs offer superior switching speed, reduced electromagnetic interference (EMI), and virtually maintenance-free operation. The ESR-60DA is ideal for controlling three-phase AC loads such as heaters, motors, and industrial equipment. Learn more about industrial electrical safety from OSHA's Electrical Safety guidelines.

Frequently Asked Questions

Q: What does the ESR-60DA solid state relay module do?

A: The ESR-60DA is a three-phase solid state relay (SSR) module that electronically switches high-power AC loads using a low-voltage DC control signal. It is commonly used in industrial heating, motor control, and automation systems where reliable, contact-free switching is required.

Q: Is the FOTEK ESR-60DA compatible with standard three-phase industrial systems?

A: Yes. The ESR-60DA is designed to work with standard three-phase AC industrial systems. It is a DA-type module, meaning it accepts a DC input signal to control AC output loads. Always verify your system's voltage and current ratings before installation.

Q: Does this module require a heatsink?

A: For high-power and continuous-duty applications, it is strongly recommended to mount the ESR-60DA on an appropriate heatsink to ensure optimal thermal management and long-term reliability. Heatsinks help dissipate heat generated during high-current switching operations.

Q: What is the current rating of the ESR-60DA?

A: The ESR-60DA is rated at 60 amperes per phase, making it suitable for high-power three-phase industrial loads such as large electric heaters, motors, and heavy-duty machinery.
