Series Overview

The design of the 3RH6 intermediate relay complies with IEC 60947 and EN 60947.
The 3RH6 intermediate relay adopts the screw terminal wiring method. The main body has 4 contacts and can be operated with AC or DC.
The 3RH6 intermediate relay is suitable for any climatic conditions and has the "finger - safe" function in line with EN 50274.

Contact Reliability

The contacts have extremely high reliability under low - voltage and low - current conditions, meeting the requirements for use in solid - state circuits. The minimum making current is 1 mA at 17 V voltage.

Surge Suppression

RC absorption, varistors, diodes, and diode combinations (combination of a diode and a Zener diode) can be plugged into the front panel of the intermediate relay to suppress surges generated when operating the coil.

Note:

Using a surge suppressor to suppress the overvoltage of the coil will cause the breaking delay of the normally open contact NO of the contactor and the closing delay of the normally closed contact NC (the suppression diode will increase the delay by 6 to 10 times, the diode combination will increase the delay by 2 to 6 times, and the varistor will increase the delay by 2 to 5 ms).

Auxiliary Contact Block

The 3RH6 intermediate relay can be expanded to a maximum of 8 contacts by adding auxiliary contact blocks. Among them, the number of normally closed contacts cannot exceed 4 (including the contacts of the main body and the added contacts).
