• Pump and compressor control applications
• General machinery automation

When it may not be suitable

This circuit breaker is specifically calibrated for motors with a nominal current between 4 and 6 amperes. It is not suitable for applications requiring higher current ratings or for protecting equipment that operates outside of this specific thermal range. Additionally, it should not be used in environments with extreme moisture or corrosive gases unless housed in an appropriate protective enclosure.

Key specifications

• Current adjustment range: 4-6A
• Protection type: Thermal overload and magnetic short-circuit
• Mounting type: DIN rail or panel mount
• Application: Motor protection and control
• Design: Compact modular housing

How to use

Installation should be performed by a qualified technician in accordance with local electrical codes. The device is typically mounted on a standard DIN rail within an electrical cabinet. Once securely mounted, connect the power supply cables to the input terminals and the motor leads to the output terminals. After installation, the current setting should be adjusted to match the specific requirements of the motor being protected. Ensure all connections are tightened to the manufacturer's specified torque to prevent overheating.

What to consider before purchase

• Verify the full-load current rating of your motor matches the 4-6A range
• Check available space in your electrical panel for mounting
• Ensure compatibility with your existing control circuit voltage
• Confirm the environmental conditions of the installation site

Usage recommendations

Regularly inspect the device for signs of wear or thermal damage. Periodically test the trip function to ensure the protection mechanism remains operational. Always disconnect the power supply before performing any maintenance or adjustments to the circuit breaker.
