Overview

The WEG UVT-UBW250-D96 Undervoltage Release is a critical component designed to enhance the safety and operational integrity of industrial electrical systems. As an accessory for the robust WEG UBW Series Molded-Case Circuit Breakers, this undervoltage release ensures that electrical circuits are automatically de-energized when the supply voltage drops to a dangerously low level. This proactive protection mechanism is vital for preventing damage to sensitive equipment, motors, and machinery that could be harmed by sustained low voltage or subsequent voltage surges upon restoration. Engineered for reliability and performance, the UVT-UBW250-D96 integrates seamlessly with WEG's UBW breaker line, which is renowned for its comprehensive short circuit and thermal protection capabilities. The UBW Series itself offers a broad product range, extending up to 2500 Amps with multiple SCCR ratings, meeting diverse application demands across various industrial sectors. The inclusion of an undervoltage release adds another layer of sophisticated protection, making these breakers indispensable for applications where power quality is a concern. Key applications for the WEG UVT-UBW250-D96 include: * **Motor Control Centers (MCCs):** Protecting electric motors from damage due to voltage sags or loss of power, ensuring smooth startup and operation. * **Industrial Power Distribution:** Safeguarding critical loads and distribution panels in manufacturing plants, processing facilities, and other heavy industrial environments. * **Automated Production Lines:** Maintaining the integrity of automated processes by preventing unintended shutdowns or damage caused by unstable power supply. * **Emergency Power Systems:** Ensuring that backup power systems are engaged correctly and that primary circuits are safely isolated when voltage conditions become unacceptable. The WEG UBW Series circuit breakers, equipped with accessories like the UVT-UBW250-D96, are UL 489 Listed, signifying adherence to stringent safety and performance standards. They are designed for panel mounting and feature ambient temperature compensation, operating effectively within a wide temperature range of -20°C to +70°C (-4°F to +158°F). This makes them suitable for challenging industrial environments. The availability of options such as maintenance mode for superior arc flash protection further underscores WEG's commitment to safety and advanced engineering. Choosing WEG for your circuit protection needs means investing in quality, reliability, and uncompromising protection for your valuable assets and personnel.
