DY-22C/60C Voltage Relay_DY-22C/60C Relay_Wiring Diagram

Application range of DY-22C/60C voltage relay

DY-22C/60C voltage relay is used in relay protection circuits for voltage rise (overvoltage protection) or voltage drop (low voltage lockout) of generators, transformers, and transmission lines.

Main technical parameters of DY-22C/60C voltage relay

● Action time: When the overvoltage relay is at 1.2 times the setting value, the action time is not more than 0.12s; when the low-voltage relay is at 0.5 times the setting value, the action time is not more than 0.15s

Contact capacity: In a DC inductive load circuit with a voltage not exceeding 250V, current not exceeding 5A, and time constant of 5 ± 0.75ms, the output contact of the product has a breaking capacity of 50W. Under the specified load conditions, the output contact can reliably operate and return 5 × 104 times. The long-term allowable current for the output contact is 5A

Dielectric strength: When the conductive terminals of the product are connected together, they can withstand an AC voltage of 2000V (effective value) 50Hz for 1 minute without insulation breakdown or flashover between exposed non charged metal parts or shells.

● Contact form: l dynamic closing, 1 dynamic breaking, 1 dynamic closing and 1 dynamic breaking, 2 dynamic closing, 2 dynamic breaking
