The design of lockout relays is electro-mechanical, hinged armature type.It has been ensured to have consistent electrical & magnetic qualities while designing the Armature, Yoke and the core materials. The coil is wound with wires with high thermal rating to withstand the problems of over heating due to continuous
rating. It is also ensured that the coil though rated for the very short time will tolerate the higher burden to ensure the faster operation. The series break contact will ensure the supply is cut off at a very short time of 10 ms breaking the inductive current.
