Motor overload relay, 1NO1NC ZE-2.4 014479

Motor Overload Relay – Reliable Motor Protection

This overload relay from Eaton is a key component for protecting electric motors. Designed for direct mounting in DILE(E)M series contactors, it provides effective protection against overload and short circuit. This is particularly important in industrial applications where failures can lead to costly downtime.

Application and functionality

This relay is designed for a wide range of applications – from simple installations to more demanding systems, including those in potentially explosive environments (EEx). Thanks to its phase failure sensitivity, compliant with IEC/EN 60947 and VDE0660 T.102 standards, it minimizes the risk of motor damage caused by voltage asymmetry. A reset button and automatic reset function simplify resetting after activation, reducing repair time and increasing work efficiency.

Construction and characteristics

The device is characterized by a compact design, allowing for easy integration with existing systems. Screw connection of the main contacts ensures a secure and durable electrical connection. A tripping class of 10A guarantees appropriate selectivity in the protection system. Additionally, the relay meets safety requirements – touch protection according to EN50274 ensures safe operation. Protection class IP20 protects against contact with solid foreign objects with a diameter greater than 12.5 mm.

The relay allows for precise adjustment to the load characteristics thanks to the current setting range from 1.6 to 2.4 A. A wide range of operating voltages, reaching up to 690 V, ensures compatibility with various installations. Status indication and control of other devices are carried out using auxiliary contacts – one normally open (NO) and one normally closed (NC). Automatic reset speeds up system restart after removing the cause of the activation. Direct mounting simplifies installation and optimizes space utilization in the control cabinet. Compliance with applicable standards guarantees safety and reliable operation in various working conditions.
