LC 3 Phase SSR 10AA 25AA 40AA 60AA 80AA 100AA 120AA 70 280V Control 24 480V AC Three Solid State Relay AC AC AC AC 120A

Relays Relay STEP 1: Choose a correct control Mode AA: AC Control AC DA: DC Control AC STEP 2: Choose a correct type for current For Resistive load: Current of SSR 2 x working current of load For Inductive load: Current of SSR 6 x working current of load For Capacitive load: Current of SSR 10 x working current of load STEP 3: Choose a suitable heat sink. When SSR working it will give out a lot of heat so in order to extend the life of your SSR please install a heat sink also if the current is over 60A the cooling fan also required. And don't forget apply heat conductive silicon grease between SSR and heat sink.
