Potential relay wiring diagram. This pickup voltage is potential voltage that exists in the start winding when a motor gets above about 75 running speed and it is generated in the start winding by the motor itself not the capacitor. It makes the procedure for building circuit simpler. Potential starting relays consist of a high resistance coil and a set of normally closed contacts. The coil is energised by the potential of the start winding. The most frequent applications include air conditioning commercial refrigeration heat pump etc. Rva potential relay is designed to start single phase motors which employ both start and run capacitor csr and csir configurations for high starting torque.
Potential relays mars series 191 c38 the largest selection of motors components and accessories for the hvacr industry features. Potential relays commercial refrigeration youtube potential relay wiring diagram the diagram offers visual representation of a electrical arrangement. The coil is wired between terminals 2 and 5 with the contacts between terminals 1 and 2. 5060 hz culus contact rating 35 amp 400 vac operating position tab up instructions and wiring diagram included in each relay class b insulation 200 18512 02 159 138 169 08. Copeland potential relay 040 0166 19 wiring wiring diagram potential relay wiring diagram. Terminals 4 and 6 are used for capacitors andor condenser fan connections and have no electrical significance to the starting relay itself as shown in figure 1.
Explaining the differences between current relays and potential relays and their role in starting compressors. David jones 280179 views. The potential relay is normally closed and it opens when a sufficient pickup voltage is present between the 5 and 2 terminals on the relay. With the assist of this e book youll be able to very easily do your own personal wiring tasks. You are able to often depend on wiring diagram as an important reference that may assist you to preserve money and time.
