Introduction
Part of the part of the chart, the appendix using GB 10963.1 chart, appendix. Part of the content, including the corresponding chart, modify the supplement
Forming an independent GB/T 10963.3.
Household and similar places with overcurrent protection circuit breakers
Part 3. Circuit breakers for direct current
1 Scope
This part of GB 10963 specifies the technology of unipolar and diode circuit breakers (hereinafter referred to as circuit breakers) suitable for operation in direct current circuits
Technical requirements. These requirements include terms and definitions, classification, circuit breaker characteristics, signs and other product information, standard use of working conditions, knot
Structural requirements and the relevant test requirements and test methods necessary to ensure the reproducibility of the test results.
Single-pole circuit breaker is rated DC voltage does not exceed 250V, two-pole circuit breaker is not more than 500V DC voltage, rated current is not
More than 125A. These circuit breakers are designed for use by untrained personnel and require no maintenance.
The circuit breakers in this section are expected to be used in an environment of pollution level 2. The circuit breaker in this section is isolated.
The circuit breakers in this section are also suitable for use with a DC power system with a floating power supply (ungrounded) that meets specific short circuit test requirements.
This section also applies to circuit breakers with several rated currents as long as they are changed from one rated value to another during normal operation
The value of the appliance is not touchable and the tool can not be changed without its rating.
For protection levels higher than IP20 in GB 4208, and often in harsh environmental conditions (such as overheating, overheating, subcooling or dust
And circuit breakers used in hazardous locations such as those prone to explosion, may require special construction.
This part of the circuit breaker has the characteristics of preventing accidental disconnection, and is not affected by the impact current and the electrical load.
Note 1. For more severe overvoltage conditions, a circuit breaker conforming to other standards (eg GB 14048.2) should be used.
Note 2. For environments with higher levels of contamination, a housing with a suitable degree of protection should be used.
