Scope of Application

TXCM1 Molded Case Circuit Breaker, is new circuit breakers which have been designed and developed by the company using international advanced technology. The circuit breakers are of the following characteristics: compact size, high breaking capacity, short arc-over distance and shakeproof, is ideal products applied on land or ships. The rated insulation voltage of the circuit breaker is 800V (500V for TXCM1-63), it is suitable for the distribution network of AC 50Hz / 60Hz, rated working voltage of 690V and rated current of 1250A, to distribute power and protect circuit and power equipment from being damaged caused by overload , short-circuit, under-voltage and other fault. Also for protection infrequent conversion of the circuits and infrequent start of motor and overload, short circuit, under voltage.
TXCM1 can be mounted vertically (upright) or horizontally (transverse).
TXCM1 meets the standard: GB14048.2 "low-voltage switchgear and control equipment, Part 2: circuit breakers."

Normal operating conditions

■ Ambient air temperature: -5℃~+40℃, and average temperature in 24h is below +35℃.
■ Altitude: The altitude of the installation site is not more than 2000m.
■ Atmospheric conditions: The air relative humidity in the highest temperature +40℃ is not more than 50%; In the low temperature can have higher relative humidity. The maximum average relative humidity is 90%, while the average monthly minimum temperature is +25℃, and consider the temperature changes in product on the surface of the gel.
■ Pollution Degree: 3.
