The lockout relay CLR series are voltage operated single element electro-mechanical, hinged armature type relay mainly used in protection, control & alarm circuits. CLR relays are available in two basic model CLR-H and CLR-S. Lockout relay CLR-H is provided with hand reset contacts. CLR-S is self reset type.
The CLR series of relays are used in various application such as: –
- Switching functions in protection and control circuits
- High speed tripping functions requiring a number of simultaneous switching operation
- Control with interlocks and inter tripping
The design of lockout relays is electro-mechanical, hinged armature type. It has been ensured to have consistent electrical and magnetic qualities while designing the armature, yoke and core materials. The coil is wound with wires of high thermal rating to withstand the problems of overheating due to continuous rating. It is also ensured that the coil though rated for the very short time will tolerated the high burden to ensure faster operation.
