When it may not be suitable

This contactor is designed specifically for 24V AC 50Hz control signals. It is not suitable for applications requiring DC control voltage or different AC frequencies without appropriate modifications or external converters. Additionally, it should not be used in environments that exceed its specified environmental protection ratings or current capacity limits.

Key specifications

• Rated operational current: 65A
• Number of poles: 3
• Control circuit voltage: 24V AC 50Hz
• Auxiliary contacts: 1 NO + 1 NC
• Mounting type: DIN rail or panel mount

How to use

Installation should be performed by a qualified electrician in accordance with local electrical codes. The contactor is designed for mounting on a standard DIN rail or directly onto a panel surface. Ensure that the power supply matches the 24V AC 50Hz specification of the coil before connecting the control wires to the A1 and A2 terminals. Power cables should be securely fastened to the main terminals, ensuring proper torque settings to prevent overheating. Once installed, the auxiliary contacts can be integrated into the control logic to provide feedback or interlock functions.

What to consider before purchase

• Verify that your control circuit provides 24V AC at 50Hz.
• Ensure the 65A current rating is sufficient for your specific load requirements.
• Check available space in your electrical enclosure for mounting.
• Confirm that the auxiliary contact configuration meets your control system needs.

Usage recommendations

Regularly inspect the terminal connections for tightness and check for any signs of wear or debris accumulation to ensure optimal performance and safety over the long term.
