Nader Circuit Breaker

The contact is not in good contact. After the power failure, the incoming and outgoing wires must be tightened again. There may be a quality problem with the air switch itself. It is recommended that you replace it with a larger capacity air switch, and then be sure to plug in the grounding plug inst...

Vacuum circuit breakers are mostly used in high-voltage switchgear, which refers to a circuit breaker that uses vacuum as an arc extinguishing and insulating medium to open and close current in a vacuum vessel. Since the advent of vacuum circuit breakers in the early 1960s, with the improvement of va...

The selection of low-voltage circuit breakers should pay attention to the following points. The rated current and rated voltage of the low-voltage circuit breaker should be greater than or equal to the normal working voltage and working current of the line and equipment. The limit making and breaking...

Low-voltage electrical appliances choose circuit breakers with different types of short-circuit breaking capacity to meet the needs of different line expected short-circuit currents (when I is in the same situation). The selection principle of circuit breaker is: 1. The short-circuit breaking capacit...

High-voltage circuit breakers have arc extinguishing capabilities and are the main equipment for circuit breakers. Normally, according to the operation requirements of the grid, some electrical equipment or lines are put into or out of operation. When the electrical equipment or line fails, the prote...
