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 are threshold, providing protection against potential damage or hazards due to low voltage conditions.

Key Features and Functionality:

Voltage Monitoring: The U01JLD6 continuously monitors the AC voltage supply to which it is connected.
Under Voltage Protection: It is designed to trip the associated circuit breaker when the monitored voltage falls below a preset threshold.
Adjustable Settings: The trip threshold (voltage level) can be adjusted to suit specific application requirements.
Trip Delay: Some models may include a configurable delay before tripping to accommodate brief voltage fluctuations or transient conditions.
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.
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.
