Doepke's protective relay is an electromagnetically operated remote switch for high electrical loads. It allows a larger current to be switched using a smaller control current. They ensure galvanic isolation between the control circuit and the switched circuit. The HS series installation relays operate very quietly and are extremely low in hum. They are characterized by their long mechanical and electrical lifespan. Their magnetic coil is suitable for continuous operation (100% duty cycle). Devices of this type are operated with a control voltage of 230 V AC.

Features:

• Wide range of different contacts
• High electrical and mechanical lifespan
• Extremely low in hum
• Suitable auxiliary switch and sealing cap available

Mounting type:

• Quick mounting on a mounting rail
• Installation position is flexible

Applications: Installation relays are versatile and can be used in residential and commercial buildings as well as industrial plants. They are responsible for switching incandescent lamps, fluorescent lamps, transformers for halogen low-voltage lamps, mercury vapor high-pressure lamps, metal halide lamps, sodium vapor, low and high-pressure lamps, storage heaters, or drives.

Notes:

• The designation of the devices in this series includes both the rated current (first pair of numbers) and the contact configuration (last pair of numbers): For example, an HS 25-31 has a rated current of 25 A, three normally closed contacts, and one normally open contact.
• For ambient temperatures above 40 °C, the use of the device is recommended.
