🔹 Description

The 3VJ9018-0ST37 is a high-voltage shunt trip unit used in industrial safety and automation systems. When a control voltage is applied, the coil energizes and mechanically trips the MCCB instantly, disconnecting the supply.

This variant is typically used where higher control voltage (415V AC class) is required for remote tripping applications in heavy industrial panels.
