HT3020

The Schneider Electric HT3020 trip unit functions within H-frame circuit breakers. It provides effective protection at a continuous trip unit rating of 20 Amps. This unit employs thermal-magnetic technology, making it well-suited for varying load conditions. Designed to operate at a maximum voltage of 600 V AC, it is compatible with standard AC circuits. The trip unit consists of three poles, allowing for versatile installations in multi-phase systems.

A short circuit breaking capacity of 80% enhances its safety performance, ensuring it can handle demanding fault currents. The installation requires a tightening torque of 8 lbf.in, which allows for secure connections within electrical panels. This trip unit adheres to UL standards, ensuring compliance with industry safety requirements. It is classified under protection class IP20, indicating that it provides adequate defense against solid objects larger than 12.5 mm, though not waterproof. Additionally, the HT3020 is enclosed in a NEMA 1 rated housing, suitable for indoor applications where dust and debris exposure is minimal.
