Made entirely from 316 stainless steel, the new Kirk 316 Series of trapped key interlocks is suitable for applications that require resistance to high temperature and/or corrosion. This new line of trapped key interlocks offers a key and cylinder mechanism with no openings and very few moving parts. The shaft driven design helps resist dirt and debris from impeding normal interlock operation. The gas-ketted key and dust cover further prevent debris from entering the interlock cylinder. All the components of the Kirk 316 Series are electro-polished or passivated. Common applications for the interlocks include: electrostatic precipitators, switchgear applications, substations, refineries, mining, conveyors, machine guarding, gantry cranes and standby power.
