This is SSR-40DA Solid State Relay Module 3-32VDC/24-380VAC 40A. A solid state relay (SSR) allows you to control high-current AC loads from lower voltage DC control circuitry. Solid state relays have several advantages over mechanical relays.

One such advantage is that they can be switched by a much lower voltage and at a much lower current than most mechanical relays. Also, because there are no moving contacts, solid state relays can be switched much faster and for much longer periods without wearing out.

This particular SSR can switch current loads of up to 40A with a 3-32V DC input and a zero cross trigger control method. Each one of these relays is equipped with four screw terminals (for use with ring or fork connectors) and a plastic cover that slides over the top of the relay to protect the terminals.

  1. Long service life and high reliability

    Nicely working. I have installed it in Air conditioner to cut off outdoor unit. Original breaker is electromagnetic contactor which got damaged because sparking and welding of contacts. For the same i have installed 40a ssr and its working very nicely
