Three phase solid state relays
12 February 2019
Joining Carlo Gavazzi's range of RGC solid state relays, the RGC3-48 with integrated heatsink can be used to replace mechanical contactors, especially when switching is frequent.
The RG Series is said to offer reliable operation, longevity, transient overvoltage protection, robust construction, excellent vibration resistance and – at higher current ratings – it utilises forced ventilation, which ensures minimal machine downtime and extended product lifetime due to reduced thermal and mechanical stress. A fan with power can be added if required.
In addition to resistive and slightly inductive loads the RGC is certified for motor switching with associated motor ratings. The space-saving design range up to operational current of 65AAC per pole for 3 pole switching or 75AAC for 2 pole switching in a 70mm wide footprint. The new RGC3-48 has an operational voltage to 48AAC per pole at 40°C and a control voltage of 5-32VDC, 20-275 VAC/124-190 VDC.
The new RGC3-48 can easily handle large cables up to 25mm2/AWg3 and offers certified motor ratings to 11kW@400VAC, 25HP@600VAC, as well as optional integrated monitoring for SSR and resistive load malfunction with alarm output for remote signalling with the RGC-M.
The RGC3.-48 is suitable for applications such as plastic injection machines, extrusion machines, blow moulding machines, thermoformers, dryers, electrical ovens, fryers, shrink tunnels, air handling units, sterilisation equipment, climatic chambers, ovens and furnaces and is CE, UL, VDE, EAC and CCC certified.
