Automatic Off Switch ETI 002135718 circuit protection switch accessory

The ETI Automatic Off Switch is an electrical accessory designed to provide automatic disconnection of circuits when connected to compatible protective devices. It is intended to interrupt power under predefined conditions to enhance safety for equipment and personnel in industrial and residential electrical installations. The unit integrates with circuit protection systems to perform reliable switching operations without continuous manual intervention.

Advantages

The switch offers automatic operation to reduce the need for manual shutdowns and to help limit damage during fault conditions. Its compact design allows integration into existing protection setups while maintaining accessibility for maintenance. The device is engineered for consistent actuation and repeatable performance, supporting safer operation of protected circuits.

Suitable for

• Automatic disconnection of branch circuits in industrial control panels
• Supplemental protection in residential electrical distribution systems
• Integration with compatible circuit breakers and protection relays
• Applications requiring remote or automatic power cutoff in machinery or equipment

When it may not be suitable

The Automatic Off Switch is not a standalone overcurrent protective device and must be used with compatible protection equipment; it does not provide primary fault current interruption by itself. It may not be appropriate in systems where the protective device interface or mounting format is incompatible with the accessory.

Key specifications

• Function: automatic circuit disconnection actuator for protective devices
• Compatibility: intended for use with compatible ETI circuit protection devices and similar products
• Mounting: accessory-style integration with protective device assemblies
• Operation: electrically actuated switching for automatic cut-off under defined conditions

How to use

Install the Automatic Off Switch following the instructions provided by the protective device manufacturer and local electrical codes. Connect the accessory to the control or trip interface of the circuit protection device, ensuring correct wiring and secure mechanical mounting. Configure the upstream protective device and any control circuitry so the accessory operates under the intended conditions. Verify operation with functional tests after installation and perform periodic inspections as part of routine maintenance.

What to consider before purchase

• Confirm compatibility with the specific circuit protection device model and its trip interface
• Verify mounting space and mechanical interface within the panel or protective assembly
• Ensure electrical ratings and control signal requirements match the installation environment
• Check local regulations and installation standards for use of auxiliary switching accessories

Usage recommendations

Use the accessory only in conjunction with certified circuit protection devices and follow manufacturer guidance for wiring and testing. Perform commissioning tests to confirm reliable operation and schedule periodic maintenance checks to ensure continued functionality.
