Mechanical Bolt Modules
Mechanical Bolt Modules, within the mGard range, provide a purely mechanical means of isolating the mains power supply by interlocking electrical disconnect switches, circuit breakers and interlocking pneumatic valves for flow control within the process industry.
The most common application is the interlocking of electrical disconnect switches which is achieved by turning a key to extend the bolt mechanism that fits into a corresponding slot in a cam connected to the disconnects handle, once it has been turned to the 'OFF' position. The bolt can only be withdrawn once the key that operates the bolt module has been returned to its corresponding lock.
All mechanical bolt modules come in a stainless steel variant for hygienic and outdoor applications and can be fitted with stainless steel flip caps to protect against dust ingress.
