The relay features manual resetting and is compatible for direct mounting on mini-contactors BG06, BG09, and BG12, making it a versatile and reliable choice for various electrical setups.
Features & Benefits
• Offers phase failure detection for enhanced motor safety
• Designed for simple manual reset functionality
• High temperature resistance with a maximum operating temperature of +55 °C
• Supports a control voltage of 690 Vac for robust performance
• Equipped with screw terminals ensuring secure connections
• Features two auxiliary contacts for additional circuit control
Applications
• Used with BG Series mini-contactors for direct mounting
• Ideal for motor needing overload protection
• Suitable for automation in electrical and mechanical systems
• Perfect for environments requiring reliable phase failure detection
What is the importance of the manual reset feature for this relay?
The manual reset feature ensures that after an overload condition, the system cannot automatically restart, avoiding potential damage to the motor and enhancing overall operational safety.
How does the high temperature resistance of this relay benefit its use?
Operating within a range of -20 to +55 °C allows it to function effectively in diverse environments, ensuring longevity and reliability in applications where temperature fluctuations occur.
Can this relay be used in single-phase applications?
While primarily designed for three-phase systems, it is sensitive to single-phase failures, making it versatile for various motor protection scenarios where phase monitoring is required.
