Working Principle
When the control coil is energized, an electromagnetic field moves the contact bridge, closing main contacts and allowing current to flow to the motor or load. De-energizing the coil opens the contacts, interrupting the circuit.
Installation Requirements
- Mount in a suitable enclosure or control panel
- Connect power circuit conductors to main terminals
- Connect control circuit wiring to coil terminals
- Use appropriately sized cables and ensure tight connections
Usage Notes
- Ensure coil voltage matches the control supply
- Use compatible overload protection for motor applications
- Periodically inspect contacts for wear and proper operation
- Follow local electrical codes and ABB installation guidelines
