The Murphy Shockswitch 20.SS.0001 is an electro-mechanical device designed to protect equipment from damaging shock. This sensitive mechanism detect excessive shock and shutdown the equipment before further damage occurs. A set of contacts is held in a latched position through a magnetic latch mechanism. As the level of shock increases an inertia mass exerts force against the latch arm and forces it away from the magnetic latch causing the latch arm to separate and to operate the contacts. Sensitivity is obtained by adjusting the air gap between the magnet and latch arm plate. It is housed in a CENELEC certified enclosure and can be used for applications requiring an execution of EEx-d-IIC-T6.
