JOSEF intermediate relay DZY-213 DC220V board with seat in front

Description :

　　purpose

　　This series of intermediate relays is used in various protection and automatic control devices to increase the number and capacity of contacts in the protection and control circuits.

　　insulation strength

　　The relay circuit can withstand AC 50Hz, voltage 2KV, and last for 1 minute between non-conductive metal parts, casings, and circuits that are not connected to electrical appliances. The winding of the relay coil can withstand AC 50Hz voltage 1kV for 1min test

　　After the electrical lifespan, it can still meet the requirements of Sections 4.2-4.4. After adjusting the mechanical lifespan, it can still meet the requirements of Sections 4.2-4.4
