Motor overload relay, 1NO1NC ZE-4 014518

Motor protection with EATON ZE-4 overload relay

This EATON ZE-4 overload relay is a reliable solution for protecting electric motors from overload and short circuit. Designed for direct mounting in DILE(E)M series contactors, it provides effective protection in demanding industrial conditions. Thanks to its compact size, it is ideal for applications where space is limited, while high functionality is still required.

Features and application

This relay is characterized by a tripping class of 10A, which means it is suitable for circuits with a rated current of 2.4 to 4A. The use of screw connection ensures a secure and durable connection of the wires. The device has a built-in automatic short-circuit tripping function and a manual reset button, which facilitates quick restoration of installation operation after a failure. In addition, the relay has one normally closed auxiliary contact and one normally open contact, which can be used to signal the circuit status or control other devices. Compliance with IEC/EN 60947 and VDE0660 T.102 standards guarantees safety and reliability. The possibility of use in installations with EEx motors confirms its versatility and wide range of applications.

Advantages for installers and users

• Simple installation: Direct mounting in the DILE(E)M contactor eliminates the need for additional mounting elements, which speeds up installation and reduces costs.
• High reliability: Tripping class 10A and compliance with standards ensure effective protection of the motor against damage caused by overload or short circuit.
• Automatic reset function: Automatic short-circuit tripping minimizes installation downtime and facilitates its operation.
• Status signaling: The presence of auxiliary contacts enables remote monitoring of the circuit status and quick reaction to any failures.
• Safety: Touch-proof protection according to EN50274 ensures safety during device operation.
• Versatility: The possibility of use in EEx motors expands the range of applications of the relay.
• Compact dimensions: Allow mounting in tight spaces and integration with modular switchgear systems – particularly important in projects with limited space.
• Durability: Made of high-quality materials guarantees long device life even in harsh working conditions.
