TI (serie 80-86), Thermal realys - DANFOSS INDUSTRIAL AUTOMATION

Thermal overload relays, specifically the Danfoss Industrial Automation TI series (80-86), are electromechanical protection devices designed to safeguard motors and electrical circuits against prolonged overcurrent conditions caused by mechanical overload, phase failure, or phase unbalance. These relays operate on the bimetallic strip principle, where heat generated by the motor current causes a calibrated deflection that trips the contact mechanism. Key technical parameters include adjustable current ranges (typically from 0.1 A to 630 A depending on the model), trip class (Class 10 or Class 20), and ambient temperature compensation. The TI series offers manual or automatic reset modes, with auxiliary contacts for remote signaling. They are compatible with Danfoss contactors and motor starters, ensuring seamless integration into control panels.

These thermal relays are primarily deployed in industrial automation environments, including motor control centers (MCCs), conveyor systems, pumps, compressors, and HVAC installations. They are essential for protecting three-phase induction motors in manufacturing plants, water treatment facilities, and material handling systems. The relays are also used in agricultural machinery and food processing equipment where reliable motor protection is critical. Their robust design allows operation in harsh conditions, with IP20 protection for panel mounting.

The Danfoss TI series includes subcategories such as TI 80, TI 81, TI 82, TI 83, TI 84, TI 85, and TI 86, each covering specific current ranges. For example, the TI 80 covers 0.1-0.4 A, while the TI 86 handles up to 630 A. The article code structure typically follows the format "TI8X-XXX", where X denotes the series variant and the suffix indicates the current setting range. Common codes include TI80-0.4, TI81-1.6, TI82-6.3, TI83-25, TI84-90, TI85-200, and TI86-630. These relays are available with optional accessories like terminal covers and sealing caps.
