Motor overload relay, 1NO1NC ZE-6 014565

Motor overload relay – reliable protection for your motor

This overload relay is a key element in protecting electric motors, designed for direct mounting in DILE(E)M contactors. It provides effective protection against overload and short circuit, which translates to a longer motor life and minimizes the risk of costly downtime. The device is sensitive to phase failure, in accordance with IEC/EN 60947 and VDE0660 T.102 standards, which further increases the safety of the installation.

This relay is perfect for applications requiring high reliability, including in potentially explosive environments (suitable for protecting EEx motors). The design with automatic and manual reset (reset button) allows for quick restoration of operation after a failure. This gives the installer full control over the start-up and diagnostics process.

Constructional features and functionality:

• Direct mounting: Enables quick and easy integration with the contactor, saving time during installation.
• Current setting range 4…6 A: Allows precise adjustment to the load characteristics, ensuring optimal motor protection.
• Auxiliary contacts 1NO1NC: One normally closed and one normally open contact allow signaling of the relay's operating status and remote control of other installation elements.
• Automatic and manual reset: Automatic reset after cooling and the possibility of manual reset using a button provide flexible operation in different emergency scenarios.
• Compliance with standards: Meets the requirements of IEC/EN 60947 and VDE0660 T.102 standards, guaranteeing safety and reliability.
• High mechanical resistance: Designed for intensive operation in harsh industrial conditions.
• Finger-proof protection: The design meets the requirements of EN50274 standard, ensuring user safety during operation.

This relay is part of the miniature series of DILE(E)M power contactors, ideal for applications with small motors and where space saving is important – e.g. in modular enclosures. Common accessories for the entire series of miniature contactors (DILEEM, DILEM, DILEM12 and DILER) simplify inventory management and installation servicing. Screw terminals provide a stable electrical connection and facilitate wire connection.
