SSR relay ASR-340DA 40A
Three-phase electronic relays of SSR type with max current of 40 A, for working voltage 48-480VAC, controlled by voltage signal 3 - 32V DC. They are widely used displacing traditional contactors and electromagnetic relays. SSR electronic relays are devices with no moving parts and are used to connect high currents. They are most often used in temperature control systems, wherever high reliability of operation, quiet operation, absence of sparking, resistance to shock, humidity and other disturbances are required.

Dimensions

Advantages of
- Lack of any mechanical contacts, which results in several times longer life compared to traditional contactors
- No noise of shorted contacts
- No sparking
- Resistance to moisture, dust, vibrations
Application
- Heating devices: all types of resistance heaters
- Lighting control
- Control of motors (the starting current of the motor must not exceed the load capacity of the relay) in three-phase applications I recommend one relay for each phase
- Ideal for plastic processing machines (injection and extrusion machines)- work with controllers with 12 V DC output
