DETAILED DESCRIPTION

RR2A: This family of Motor Reversing Controller is designed to control the direction of 3-phase motors rated up to 5.5 kW. The built-in interlocking circuitry prevents the relay from switching both directions simultaneously and produce a short-circuit between the 2 phases of the output. A dual colour LED indicates direction "forward" when green and direction "reverse" when red. The output is protected from excessive voltage fluctuations (transients) by built-in varistors. Furthermore, optimum reliability is achieved by soldering the output thyristor chips directly on to the ceramic substrate (Direct Copper Bonding). The housing is designed to incorporate a temperature limit switch.
