What is the significance of the trip-free release feature?
The trip-free release feature ensures that the relay does not automatically reset when overloaded, allowing continuous operation while safeguarding equipment against damage. This maintains circuit integrity and operational safety during fault conditions.
How does the overload relay help with phase-failure sensitivity?
This overload relay has built-in phase-failure sensitivity, ensuring that if one phase fails, the relay will detect it and disconnect the power supply to prevent equipment damage. This feature contributes to more reliable system performance.
What are the terminal capacity specifications for this relay?
The relay accommodates various terminal capacities, including flexible terminals with ferrules ranging from 0.75 to 2.5 mm² for control circuit cables. It also supports solid conductor terminals of 1 to 6 mm² for main cables, allowing flexible installation options.
