The ESX10-103-DC24V-4A-E by E-T-A is an advanced power distribution system engineered to safeguard DC 24V circuits with comprehensive protection and monitoring capabilities. It supports a wide range of current ratings from 0.5A to 16A, ensuring flexibility and reliability across various industrial applications.

Operating within a voltage range of DC 24V (18…32V), this single-pole device excels in rapid load disconnection during fault conditions, reacting typically within 100 milliseconds for short circuits and within 5 seconds for overloads. This feature prevents damage to connected equipment and ensures the continuity of critical operations.

The ESX10-103-DC24V-4A-E incorporates a sophisticated current limitation mechanism, typically set at 1.15 times the nominal current (IN), with additional settings at 1.8, 1.5, and 1.3 times IN, allowing precise adjustment to match specific application requirements. This capability enhances safety and prevents unexpected power surges that could compromise system integrity.

For enhanced functionality, the device offers versatile signal output options including DC 30V/0.5A max (normally closed or normally open) and DC 10V/10mA min (normally closed or normally open), facilitating seamless integration with external monitoring systems or controllers. Its status output can handle up to 0.2A and is designed to be short circuit-proof, ensuring reliable operation even under adverse conditions.

A tri-color LED indicator (green, orange, red) provides clear visual feedback on system status and faults, aiding quick diagnostics and minimizing downtime. The ESX10-103-DC24V-4A-E features blade terminals of 6.3 mm for secure electrical connections and supports plug-in mounting using modules 17plus and 18plus, optimizing installation efficiency in control panels or equipment enclosures.

To ensure compliance with safety regulations and standards such as Machinery Directive 2006/42/EG and EN 60204-1, it is crucial to match the cable cross-section of the load circuit with the current rating of the ESX10 used. Additional precautions, such as employing a safety PLC, are recommended to prevent automatic system restarts following a failure, thereby enhancing operational safety.

The ESX10-103-DC24V-4A-E is available through Miken Electronics, offering superior circuit protection, precise monitoring capabilities, and robust design suitable for demanding industrial environments where reliability and safety are paramount.
