TANM1, TANM2 low-voltage plastic-enclosed circuit breakers
The TANM1 series molded-case circuit breakers (hereinafter referred to as “circuit breakers”) are among the new-generation circuit breakers designed and developed by our company using internationally advanced technologies. They are suitable for AC circuits with a frequency of 50 Hz (or 60 Hz), a rated operating voltage of 690 V or less, and a rated current of up to 800 A, and are intended for infrequent switching operations and infrequent motor starting. These circuit breakers provide overload, short-circuit, and undervoltage protection, thereby safeguarding wiring and power-supply equipment from damage.
It can be configured in a dual-power switching system to switch between the primary and backup power sources, thereby ensuring the continuity and reliability of power supply to electrical equipment.
- The installation altitude shall not exceed 2,000 m.
- The ambient air temperature shall not exceed +40°C, with a lower limit of -5°C; (see Table 6 for derating factors when the temperature exceeds +40°C up to +60°C).
- When the ambient air temperature is +40°C, the relative humidity of the air shall not exceed 50%; at lower temperatures, higher relative humidity levels are permissible—for example, up to 90% at +20°C. Special measures shall be implemented to address condensation that may occasionally occur due to temperature fluctuations.
- The pollution level is Grade 3.
- Capable of reliable operation under seismic (4g) conditions.
- It can be transported and stored within the temperature range of -25°C to +55°C.
- The circuit breaker may be installed either vertically or horizontally without compromising its technical performance.
- The circuit breaker shall be installed in locations free from explosion hazards, conductive dust, and corrosive substances that can damage metals or degrade insulation.
- The circuit breaker shall be installed in a location free from rain and snow.
