Its robust design and adherence to international safety standards ensure consistent performance and longevity in demanding environments.
Advantages
This thermal overload relay offers exceptional reliability through its differential protection mechanism, which is designed to trip quickly in the event of phase imbalance or overload. The compact dimensions allow for efficient use of space within control panels, while the high-quality construction ensures durability under continuous operation. By integrating this component into your motor control circuit, you significantly reduce the risk of motor burnout and costly downtime, ensuring that your equipment remains protected according to global industrial standards.
Suitable for
Industrial motor control circuits
Protection of small AC motors
Integration into TeSys K contactor assemblies
Automation systems requiring precise thermal monitoring
This relay may not be suitable for applications requiring current ranges outside of the 3.7 to 5.5A threshold. It is also not intended for use in environments where the ambient temperature or environmental conditions exceed the specifications defined by the manufacturer's technical documentation.
Key specifications
Current adjustment range: 3.7 to 5.5 A
Tripping class: 10A
Protection type: Differential thermal overload
Dimensions: 45 x 65 x 58 mm
Weight: 145 g
Certifications: IEC 60947, UL, CSA, VDE 0660
Ingress protection: IP2x
Installation should be performed by a qualified professional in accordance with local electrical codes. The relay is typically mounted directly onto a compatible contactor. Ensure that the current setting dial is adjusted to match the full-load current rating of the motor being protected. Once installed, verify the wiring connections and perform a test trip if the system allows to ensure the protection mechanism is functional.
What to consider before purchase
Verify that your motor's full-load current falls within the 3.7 to 5.5A range.
Ensure compatibility with your existing contactor model.
Check the available space in your electrical enclosure for the 45 x 65 x 58 mm dimensions.
Confirm that the environmental conditions meet the IP2x protection rating requirements.
Always ensure the power supply is disconnected before installing or adjusting the relay. Regularly inspect the device for signs of wear or thermal damage to maintain optimal motor protection.
