The robust construction ensures long-term durability and consistent performance even in challenging operational conditions, contributing to increased system uptime and reduced maintenance requirements.
Suitable for
Industrial automation systems
Commercial HVAC equipment
Pump and fan control applications
Conveyor belt motor protection
General power distribution panels
When it may not be suitable
This device is specifically calibrated for motor protection and may not be suitable for applications requiring protection for non-motorized loads or circuits with significantly different current characteristics. It is not intended for use in high-voltage distribution networks beyond its specified operational limits.
Key specifications
Number of poles: 3
Power rating: 4kW
Adjustable thermal release range: 6.3A to 10A
Function: Overload and short-circuit protection
How to use
The device should be installed by a qualified professional within an appropriate electrical enclosure. Once mounted on a standard DIN rail, the motor leads are connected to the terminals. The thermal release range should be adjusted using the integrated dial to match the rated current of the motor being protected. After installation, the breaker can be manually switched on or off to control the motor, and it will automatically trip in the event of an overload or short circuit.
What to consider before purchase
Verify that the motor power rating matches the 4kW specification
Ensure the motor nominal current falls within the 6.3A to 10A adjustment range
Check compatibility with existing DIN rail mounting systems
Confirm that the environmental conditions meet the manufacturer's operational standards
Usage recommendations
Regularly inspect the terminals for tightness and ensure the device is free from dust or debris to maintain optimal thermal performance. Periodically test the trip mechanism to ensure continued operational safety.
