The Electronic Timer – BTR17 Series (Model: BTR174622) is a compact and efficient Star-Delta timer specifically designed for controlling the starting sequence of three-phase induction motors. With its slim 17.5 mm width design, this timer is ideal for space-saving installations in modern control panels while delivering reliable and precise timing performance.
This timer is engineered to manage the star-delta transition process, which is commonly used to reduce the inrush current during motor startup. It initially connects the motor in a star configuration and then automatically switches to delta after a preset delay, ensuring smooth motor acceleration and protecting electrical components from overload.
The BTR174622 features an adjustable time delay range (typically 0.5 seconds to 10 seconds or similar range), allowing users to configure the optimal transition time based on motor requirements. The dial-based adjustment system ensures easy and accurate time setting, making it convenient for both installation and operation.
Designed for industrial applications, this timer supports wide voltage compatibility, typically including 230V AC or similar standard supply, ensuring seamless integration into control systems. It is built with high-quality electronic components, providing stable and repeatable timing performance even under continuous operation.
One of the key advantages of the BTR17 series is its compact DIN rail mountable design, which saves valuable panel space while maintaining high functionality. Its slim profile makes it especially suitable for modern electrical panels where space optimization is critical.
The timer is equipped with reliable relay outputs, ensuring smooth switching between star and delta contactors. This helps in minimizing electrical stress on the motor and enhances the overall efficiency and lifespan of the system.
The BTR174622 is designed to perform reliably in harsh industrial environments, with resistance to temperature variations, electrical noise, and mechanical vibrations. Its robust construction ensures long service life with minimal maintenance requirements.
Additionally, the timer provides consistent switching accuracy, ensuring proper coordination between star and delta operations. This is essential for preventing motor damage and ensuring safe and efficient operation.
Overall, the BTR17 Star Delta Timer is a dependable and cost-effective solution for motor control applications. Its compact design, precise timing, and durable construction make it a preferred choice for engineers, panel builders, and industrial automation professionals.
