Overload relay for DILM40...72 ZB65-57 278459

Motor and Circuit Protection – Reliability in Every Detail

The ZB65-57 overload relay, designed to work with DILM40…72 contactors, is a key element ensuring the safety and long-term operation of your electrical installations. The device effectively protects motors and circuits from overload, minimizing the risk of failure and downtime. Direct mounting simplifies integration with existing systems, and the robust construction guarantees reliability even in demanding conditions.

Functionality and Flexibility in One Device

This relay offers a current setting range from 40 to 57A, allowing it to be adapted to various applications. It has one normally closed auxiliary contact and one normally open contact, enabling signaling of the overload status or use in control circuits. Screw connections ensure secure and durable electrical connections. The maximum rated operating voltage of 690V makes it a universal solution for many industrial installations.

User Comfort and Advanced Solutions

The device is equipped with automatic short-circuit tripping and a reset button, making it easier to quickly restore system operation after a failure. The built-in auxiliary contact as standard (for DILM from 7 to 38A) is an additional benefit, eliminating the need to purchase additional components. This saves you time and money. Additionally, the DILM series has marine approvals, confirming its high quality and reliability in harsh environmental conditions. Toolless connection of DILM contactors from 7 to 15A with motor starter PKZM0 using connector PKZM0-XDM12 significantly simplifies installation and servicing. As standard, all contactors with DC coil have built-in overvoltage protection.
