Siemens U01JLD6 120 VAC Under voltage Trip for circuit breaker

Siemens U01JLD6 120 VAC Under voltage Trip for circuit breaker

 

The Siemens U01JLD6 is an under voltage trip device designed for use with Siemens molded case circuit breakers (MCCBs). This specific model is used to monitor voltage levels and trip the circuit breaker when the voltage falls below a certain threshold, providing protection against potential damage or hazards due to low voltage conditions. Here’s an overview of the U01JLD6 under voltage trip module:

Key Features and Functionality:

1. Voltage Monitoring: The U01JLD6 continuously monitors the AC voltage supply to which it is connected.
2. Under Voltage Protection: It is designed to trip the associated circuit breaker when the monitored voltage falls below a preset threshold.
3. Adjustable Settings: The trip threshold (voltage level) can be adjusted to suit specific application requirements. This adjustment allows customization based on the acceptable voltage tolerance for the protected equipment.
4. Trip Delay: Some models may include a configurable delay before tripping to accommodate brief voltage fluctuations or transient conditions.
5. LED Indicators: Provides visual indication of the operational status, including power status and trip condition.
6. Compatibility: Designed to be compatible with Siemens MCCBs, ensuring seamless integration and reliable performance within Siemens electrical distribution systems.

Typical Applications:

• Motor Protection: Protects motors and other electrical equipment from damage caused by low voltage conditions.
• Critical Equipment Protection: Used in critical facilities or processes where voltage stability is crucial for operational continuity.
• Voltage-sensitive Equipment: Provides protection for equipment that is sensitive to voltage fluctuations.
• Uninterruptible Power Supply (UPS) Systems: Ensures UPS systems switch to battery power or initiate other protective measures in case of low voltage events.

Installation and Configuration:

• Mounting: The U01JLD6 module is typically installed directly onto the Siemens MCCB.
• Wiring: Connects to the voltage supply and the control input of the MCCB for trip signal transmission.
• Setting Adjustment: Use the provided adjustment settings (potentiometers or dip switches) to set the desired under voltage trip threshold.
• Testing: After installation, conduct testing to ensure proper functionality and responsiveness to under voltage conditions.

Safety and Compliance:

• Always follow local electrical codes, regulations, and Siemens’ installation guidelines when installing and configuring the U01JLD6 under voltage trip module.
• Ensure that the system is properly tested and commissioned to verify correct operation under various operating conditions.
