Replacement/Crossover of Mercury Relay Contactors


Description
The 4003 series solid state power controllers will switch up to 60 Amps 3 phase, 600Vac. The Vac input unit can easily replace any mercury or magnetic contactors. The Vdc input is
compatible with existing SCRs and will work with a variety of process controllers.

The 4003 series solid state power controllers combine Chromalox’s years of SCR technology experience and know-how with new components and packaging technologies to deliver reliable and easy-to-install SCR components. The 4003 series power controllers are compactly packaged to allow for fast and easy DIN-rail or sub-panel mounting, with wiring terminals easily accessible from the front. The depth and height of all controllers in the 4003 series are consistent, optimizing the mounting and wiring of mixed controller types. Optional heatsink thermostat protects the SCRs from failure.
