Material Composition
Silver-alloy contacts, steel laminated magnetic core, thermoset plastic housing, and copper bus bars.
Structural Characteristics
Compact NEMA form factor with front-accessible terminals, arc chutes, and auxiliary contact mounting provisions.
Working Principle
When the control coil is energized, the magnetic field pulls the movable armature, closing the main power contacts and completing the circuit to the load.
Installation Requirements
- Mount on a flat, stable surface or DIN rail (if applicable).
- Ensure proper wire stripping and torque specifications for pressure box terminals.
- Provide adequate clearance for arc flash and heat dissipation.
Usage Precautions
- Always de-energize before servicing.
- Verify coil voltage matches control circuit.
- Inspect contacts periodically for pitting or welding.
