3 Phase Solid State Relays

3 Phase Solid State Solutions

The product is intended to replace electromechanical contactors when witching speeds are quite frequent. Their compact size, easy installation and flexible configuration make these devices the ideal solution, especially when retrofitting. The Goldline Series of solid state relays and contactors are designed for switching resistive as well as inductive loads

Goldline Series solid state relays and contactors are a ready-to-use, out-of-the-box solution, mainly targeting Plastics & Rubber, Packaging & Wrapping, HVAC, Furnace and Food & Beverage markets. Features include:

The 3-phase solid state switching solutions presented hereafter build on the success of the 1-phase version of the RG series whereby the same effective thermal design is adapted. This translates to one of the most compact 3-phase solid state switching solutions available in the market. The solutions offered making it easy for user to match product rating to application needs. Different switching modes are available catering for digital control signals, for example from PLCs, as well as analog signals, current or voltage, directly from temperature controllers output. The Goldline Series series covers 3-phase, 3-pole switching solutions whilst the Silverline series is a more economic version consisting of 3 switching poles.
