Structural Features
1) The rated short-circuit breaking capacity is high, and some rated current levels can reach more than 6KA.
2) Double wiring function, can easily connect standard busbar and flexible wire.
3) The combined terminal block with finger touch protection has higher safety.
4) With energy storage mechanism operation, the contacts close quickly, which overcomes the adverse
effects caused by the speed of the manual operation handle, and improves the service life of the product.
5) A variety of accessories are available, and modular, flexible combination, user installation is very convenient.
6) The shell and some functional parts are made of imported high flame retardant, high temperature resistant and impact resistant plastics.
7) High current limiting coefficient and superior cost performance.

FAQ
Q1: Selection of surge protector Al: The level of surge protector (commonly known as lightning protection) is evaluated based on the IEC61024 subdivision lightning protection theory installed at the junction of the partition. The technical requirements and functions are different. The first level lightning protection device is installed between zones 0-1, and the flow requirements are very high. The minimum requirement of GB50057 is 12.5 ka (10/350), and the second and third levels are installed between 1-2 and. 2-3 areas, mainly to suppress overvoltage. Q2: Are you a lightning protector factory or a lightning protector from a trading company? A2: We are a manufacturer of lightning surge protectors. Q3: Warranty and return？ A3: 1. Lightning surge protector products and accessories have been tested 3 times before leaving the factory. 2. We have the best after-sales service team. If there is any problem, our team will do our best to solve it for you. Q4: How to get some samples of surge protector? Answer: We are honored to provide you with samples of lightning protection devices. Please contact our staff and leave detailed contact information.
