Product Overview
Feeder terminal unit (hereinafter referred to as "Controller") is one feeder automation remote terminal unit and applicable to controlling, monitoring and protection of the breaker. If the controller is used with the breaker body of our company to form the complete breaker, the product performance is more stable and reliable. When the controller is matched with A12M-OVB, A12MG-OVB, A12S-OVB and A12SG-OVB breaker bodies, the outdoor intelligent vacuum breakers and auto re-closer can be formed, and when matched with the A12VSP breaker body of our company, the outdoor intelligent cutoff breaker can be formed.
The controller is equipped with the stainless steel shell with protection class achieving IP56; and the backup battery and the management system are arranged in the AIC-3 controller. The controller is featured with functions, including handhold remote control, three-section current protection, inverse-time protection, intelligent cutoff control zero-sequence current protection and three-time re-closure. The operating panel has the rich man-machine interface and LCD menu in Chinese, with "4 remote" function, functions of measuring voltage, current and power and recording the fault event, and the radio communication is accessible for the controller optionally.
Improved protection function
