Application
The THQL series products are suitable for alternating current with a voltage of 600V or less and a frequency of 50/60HZ. In single-phase and three-phase circuits. It is used for short-circuit protection, overload protection, power switches, etc. It features high breaking capacity, fast response speed and long service life.
The black shell is made of fiberglass material. The moving contacts, static contacts and rear seat are all made of all-copper components, with 30% composite silver dots.
