SSR 40AA, 40 Amps AC To AC Solid State Relay

Introduction:

• The Lorentzzi® SSR-40AA is an AC control AC SSR with a control voltage of 70-280VAC and a load voltage of 24-480VAC.
• This 40A solid-state relay is designed for resistive loads such as heating elements, and the maximum power of the heating element can reach 4.4 kW when the load voltage is 220VAC.
• In addition, we can also use it to control inductive loads such as motors and compressors, but the load rated power should be less than 1.2 kW, because the starting power of inductive loads is usually 5-7 times its rated power.
• The control and load terminals of SSR 40AA are made of brass terminals, which have low resistance, high conductivity and can withstand high current.

• Our solid relays are equipped with transparent protection cover, which can not only be used to prevent dust and moisture, but also avoid the risk of electric shock.
• This 40 amps AC to AC solid state relay has an LED indicator light, which allows users to clearly see its working status.
• Its base plate is made of high-quality aluminum or copper to ensure good heat dissipation of the internal load control components.
• Please note that since this solid state relay generates a lot of heat when the load is connected, it needs to be used with our heat sink. We recommend using our W-110 screw-on heat sink or D-74 din rail heat sink.
• The typical wiring diagram between the SSR and the PID temperature controller is shown below:
