EATON Time delay undervoltage module

The installation and maintenance of modules must be operated by qualified electrical personnel and strictly comply with the following safety rules:

Power off operation: Before contacting the equipment, the power supply of the main circuit and control circuit must be disconnected.

Circuit breaker position: Drawer type circuit breakers should be shaken out to the isolation position.

Spring energy storage release: All circuit breakers should be placed in the "OFF" position and release the mechanism spring.

Prevent accidental restart: Ensure that the device cannot be unexpectedly powered on again.

Isolation verification: Confirm complete isolation from the power supply, and if necessary, perform grounding and short circuiting.

Protection of adjacent live parts: Cover or set up barriers for adjacent live parts.

Warning: Failure to follow the above steps may result in death, personal injury, or property damage.

Application scenarios

Industrial production line: To prevent the entire production line from shutting down due to transient voltage drops in the power grid, ensuring continuous production.

Key infrastructure, such as data centers, hospitals, and traffic control systems, to avoid false tripping and impact on critical loads.

Generator and backup power switching scenario: During the power switching process, use the delay function to smoothly transition and avoid misoperation.

Remote control and emergency stop: Emergency release is achieved through external buttons to meet safety interlock requirements.
