Solid State Relays SOLITRON MINI With Integrated Heatsink • AC Solid State Contactor in 22.5 mm housing • Zero switching for heating and motor applications • Rated operational current 10 A and 20 A • Rated operational voltage 120/230 VAC, 400/480 VAC and 600 VAC • Transient overvoltage protection • LED-indication • IP 20 protection • DIN-rail and backplate mountable • Terminal layout as contactor or SSR standard • Insulation > 4000 V Product Description The SOLITRON Mini Solid State Contactor is designed for industrial heating and motor applications. The Solid State Contactor is designed for DIN-rail and backplate mounting with integrated heatsink and overvoltage protection. The heatsink is moved to the back for optimal space-saving in the panel and easy wire mounting at the front of the relay. The limited current rating limits the need for optimal convection Ordering Key cooling as provided with Solitron 30, 50 and 63 A versions. The contactor elements are integrated on to the ceramic providing more than 4000 V insulation to the heatsink. AC or DC controlled versions are available with terminal layout as the standard for contactors or the US Milstandard for Solid State Relays. Built-in LED status indication for applied control voltage.

Thermal measurements after installation must be made to secure correct ambient temperature. The ambient temperature is the temperature of the air flow just before it reaches the relay. A minimum distance of 120 mm must be kept between two rows of Solid State Contactors. Please refer to the drawing Panel Mounting. The ambient temperature in the top of a panel can be substantialy higher than the inlet temperature of the cooling air.
