Miniature circuit breaker product selection

In the civil building design, the low-voltage circuit breaker is mainly used for line overload, short circuit, over current, voltage loss, under voltage, grounding, leakage, automatic switching of dual power supply and protection and operation of the motor during infrequent starting. In principle, in addition to the basic principles of complying with the environmental characteristics of low-voltage electrical equipment (see the Industrial and Civil Power Distribution Design Manual), the following conditions should be considered:

1) The rated voltage of the circuit breaker should not be less than the rated voltage of the line;

2) The rated current of the circuit breaker and the rated current of the overcurrent release are not less than the calculated current of the line;

3) The rated short-circuit breaking capacity of the circuit breaker is not less than the maximum short-circuit current in the line;

4) Selective power distribution circuit breakers should consider the short-delay short-circuit on-off capability and the delay protection level;

5) The rated voltage of the undervoltage release of the circuit breaker is equal to the rated voltage of the line;

6) When used for motor protection, select the circuit breaker to consider the starting current of the motor and make it not operate during the starting time; for the design calculation, see the "Industrial and Civil Power Distribution Design Manual";

7) Circuit breaker selection should also consider the selective cooperation of circuit breakers and circuit breakers, circuit breakers and fuses.

Flame Retardant Braided Sleeve

Description for Flame Retardant Braided Sleeve


Expandable braided sleeves is ideal for a limitless number of electronic, automotive, marine and industrial wire management and bundling applications. Examples include engine compartment dress up, home theater wire management, customizing computer case wiring, office wire management, automotive harnesses, scuba hose protection, and many more. Threads of different colors and textures could be braided into different patterns. Each of our products is tailored to the client's business and needs.


PET polyester Expandable Braided Sleeving is flame-retardant and halogen-free. It offers durable abrasion resistance in a wide range of industrial applications. The open weave construction allows an easy installation on a bundle of hoses and cables, even if some with bulky or large connectors.
Totally expanded the sleeving can reach at least one point five times than the initial dimension.


PET expandable braided sleeve compiled by the Environmental Protection PET filament diameter monofilament 0.20mm or 0.25mm's made with good flexibility, flame resistance, abrasion resistance and heat resistance, network management can be easily expanded to the original 150% , and it is easy to tighten the various irregularly shaped objects, which can be maintained within a wide temperature range while maintaining a soft, can inhibit chemical corrosion, UV and friction, characterized by its unique mesh also has good ventilation, wire heat diffusion function in a timely manner.
