The electrical power industry has a great variety of requirements for latching type auxiliary relays to provide maintained contacts -- both N/C and N/O. Often, manually operated switches are used in conjunction with traditional relays to provide the "maintained" function. However, traditional protective relays have limitations as to the number of contacts available and their ability to withstand seismic vibration. Traditional auxiliary relays used in conjunction with the protective relays also exhibit these limitations. tion rotary action Latching Switch Relay that provides control of up to 20 N/O and 20 N/C contacts in a single device. It is a manually or remotely operated unit used for a variety of applications; latching relay, reclosing relay, programming relay, and local/remote switch that is SCADA compatible. Standards: ANSI/IEEE C37.90, ANSI/IEEE C37.90.1, ANSI/IEEE C37.98, ANSI/IEEE C37.105, ANSI/IEEE 323, ANSI/IEEE 344, ANSI/ASME NQA -1. industry immediate delivery Professionals stand behind every Electroswitch product.

Specifically, two N/O contacts and two N/C contacts are provided in each deck, and ten decks can be stacked, resulting in a relay with up to forty contacts. This deck arrangement is illustrated in Fig 1. however, it is suggested that polarized voltages should not be used on adjacent contacts. This is because of the remote possibility of flashover during transition between adjacent contacts -– especially at the higher DC ratings, or in highly inductive circuits. ond digit of the terminal number is the same as the deck number. contact used together with terminal 84.
