Three-Phase Relays for Harsh Environments
Crouzet introduced its GN3 series of three-phase and motor reversing solid-state relays that have optimal thermal efficiency and noise immunity. The EMC compliant design (level 3) and built-in transient protection provide reliability in harsh industrial environments. These relays are suited for a range of three-phase motor and heating functions, as well as in switching multiple outputs with a single control signal. They are available with ratings up to 50A per phase at 600V AC (530V AC with internal snubber network), with either a DC, AC or low-voltage AC (18V AC to 36V AC) input. Industrial applications include mercury relay replacement, professional food-service equipment, sterilizers, temperature control systems, plastic extrusion/thermoforming machinery, packaging equipment, sorting equipment, lighting systems, pump controls, incubators and UPS systems.
