A contactor relay is an electrically-controlled switch to manage a power circuit. Contactors are designed to be directly connected to load devices with higher power loads. You can find contactors to operate on AC or DC, and they use either spring-loaded or screw tech. The basic contactor relay will only include 4 poles, but it’s easily extendable to 8 thanks to snap-on auxiliary contact blocks.
3 Pole Contactors
Any appliances and devices for small and low-noise relays and contactors will require general purpose relays. As they’re the simplest of the bunch, you can use them for basic controls as well as large-scale controls and devices, from buzzing systems in an apartment complex to alarms. They’re perfect when you only need one auxiliary contact and don’t require an overload relay. General purpose relays can place increased requirements when it comes to switching capacity, which in turn translates to switching voltage and service life.
