Solid state relay overload 1NO1NC ZE-12 014752

Motor Protection and Reliable Operation – Overload Relay ZE-12

This silicone overload relay, designated ZE-12 and catalog number 014752, is a key element in protecting electric motors. It provides effective protection against overload, which translates to a longer lifespan of devices and minimizes the risk of failure. This relay is particularly useful in applications with three-phase motors, such as pumps, fans, lifts, and hoists.

Functionality and Application

The ZE-12 relay is designed for direct mounting, simplifying installation and saving time. It has one normally open auxiliary contact (1NO) and one normally closed auxiliary contact (1NC), allowing integration with various control and signaling systems. With a release class of 10A, the relay reacts quickly and precisely to current increases, protecting the motor from damage. The built-in reset button allows manual resetting after a shutdown caused by an overload, and the automatic reset function increases convenience in applications where short-term current surges are permissible.

Characteristics and Benefits for Installers and Users

• Wide current setting range (9…12 A): Allows adaptation to different types of motors and loads.
• High reliability: Ensured by a reputable manufacturer – Eaton Electric – guarantees long-lasting and trouble-free operation.
• Safety: Compliance with safety standards ensures protection for both the motor and the entire electrical system.
• Simple installation: Direct mounting simplifies and speeds up installation.
• Status indication: The presence of auxiliary contacts allows easy monitoring of the circuit status and quick response in the event of a failure.
• Interference resistance: Rated insulation voltage of 690 V ensures stable operation even in harsh environmental conditions.
• Fault reset: Both manual (button) and automatic reset facilitate restoring system operation after short-term overloads.

This relay is an ideal solution for both professional installers looking for a reliable component for motor protection systems and end-users wanting to protect their equipment from damage caused by overload. Connections are made using screw connection, which further increases comfort during installation.
