HYB1-125 Over/Under Voltage Protection Circuit Breaker

①. It adopts modular structure to form a whole, fixed with 35mm standard rail, which is convenient for quick installation, maintenance or replacement;
②. It has manual/automatic switching function, which is safe and reliable;
③. The circuit breaker has built-in linkage shaft of each pole handle, and the closing synchronization is good;
④. Low standby power consumption, energy saving, low carbon and environmental protection;
⑤. It adopts C65 small circuit breaker platform, energy storage free tripping mechanism, and fast contact closure; the energy storage structure is optimized, the opening and closing synchronization is reliable, and the electrical life is long;
⑥. The overload and short circuit protection functions are integrated with the automatic opening and closing operating mechanism.

Scope of application:
HYB1-125 type electric energy meter external circuit breaker (hereinafter referred to as circuit breaker) is suitable for lines with rated working voltage up to 230V or 400V, AC 50Hz, and rated current up to 125A. It can automatically disconnect the power supply for long-distance arrears and automatically close the power supply for payment. At the same time, it plays the role of overload and short circuit protection for the line, and can also be used for infrequent operation conversion of the line. At present, it is widely used in conjunction with IC card prepaid electric energy meters to control the automatic disconnection and automatic closing of the line. At the same time, it can feedback the three states of closing, opening, and fault.
It complies with the "Technical Specifications for External Load Switches for Electric Energy Meters" of the State Grid Corporation of China.

Conditions of use
① Ambient air temperature: -25℃～+65℃; Extreme working temperature -40℃～+70℃;
② The altitude is generally not more than 2000m;
③ Standard rail TH35～7.5 type installation rail is adopted;
④ Installation conditions: The circuit breaker should generally be installed vertically, the inclination angle shall not exceed 5°, the handle is upward for the power supply, and there should be no significant impact and vibration at the installation place.
