IV. Structure and Composition

• Main contacts: Carry 600A current and are responsible for the on-off of the main circuit.
• Coil: Drives the electromagnetic mechanism to trigger contact action.
• Auxiliary contacts: Provide signal feedback for control loops or interlocking logic.

V. Application Fields

Industrial Automation

Power Systems

Special Industries

Other Fields

VI. Installation and Maintenance

Installation Steps

• Power-off operation: Ensure the equipment is powered off before installation.
• Check integrity: Confirm that the equipment has no physical damage.
• Wiring specifications: Connect the main circuit and control circuit according to the drawings to avoid short circuits.
• Reserved space: 100mm maintenance space needs to be reserved.

Maintenance Suggestions

Regular Inspection:

• Check whether the wiring is loose or aging.
• Clean the contact surface to prevent oxidation or poor contact.

Abnormal Handling:

• Monitor the heating of the coil to avoid faults caused by overheating.
• Replace severely worn contacts or coils in time.
