TGM1P series moulded case circuit breaker is suitable for power distribution system. It is a mechanical switch used to make, carry, and break current under normal circuit conditions and to make and carry current for some time and break current under specified abnormal circuit for protection of lines and equipment in case of overload or short circuit of power distribution line.
This series circuit breaker has overload and short-circuit protections and motor electric operating mechanism, and there are manual and electric models available.
Working environment conditions:
1.1 Ambient temperature: Normal operating temperature: -10℃ ~ +70℃;
1.2 Installation category: Main circuit: III; other auxiliary circuit: II.
1.3 Pollution degree: 3.
1.4 Altitude: Not exceed 2,000 meters; derating is required when greater than 2,000 meters.
1.5 Atmospheric conditions
(1) The relative humidity shall not exceed 50% at ambient temperature +40℃;
(2) A higher relative humidity is allowed at a lower temperature.
For example, up to 90% at 20℃. Special measures shall be taken for condensations caused by temperature changes.
1.6 Impact vibration
Circuit breaker passes the test specified in GB/T2423.10, and can withstand mechanical vibration with a frequency 2Hz ~ 13.2Hz and a displacement of ±1mm and with a frequency of 13.2Hz ~ 100Hz and a acceleration of ±0.7g.
