TGM3E

TGM3E series moulded case circuit breaker has the characteristics of four sections of selective protection, zero flashover, high breaking, box-type accessories, small and compact structure, green and environmental protection.
It has the rated isolation voltage of 1,000V. It can be used for occasional circuit switch and startup of motor in circuits under AC 50/60Hz, with the rated working voltage ≤690V and setting current of 12.5A-1,250A.
The circuit breaker can be equipped with communication modules, so as to upgrade the original circuit breaker to a communication circuit breaker easily, achieving “four remote” functions, namely remote control, remote adjustment, remote measurement and remote signaling.

Overview

Working environment conditions:

1.1 Ambient air temperature is -5ºC to +40ºC;

1.2 The relative air humidity at the installation site shall not exceed 50% at a maximum temperature of +40ºC. A higher

relative humidity is allowed at the lower temperature. For example, the relative humidity can reach 90% at 20ºC. Special

measures should be taken to deal with occasional condensation due to temperature changes;

1.3 Pollution class is 3;

1.4 The circuit breaker is required to withstand mechanical vibration with the frequency of 2Hz-11.2Hz, displacement of

±1mm and mechanical vibration with the frequency of 11.2Hz-100Hz and accelerated velocity of ±0.7g;

1.5 The installation category is III for main circuits of the circuit breaker and II for other auxiliary circuits and control

circuits;

1.6 The circuit breaker shall be applicable to electromagnetic environment B;

1.7 Hot and humid band type (TH type) circuit breaker can withstand the effect of damp air, salt mist, oil mist and mold;

1.8 The circuit breakers should be installed in a place without explosive hazard, conductive dust and corrosion against metal

and damage to insulation;

1.9 The circuit breaker shall be installed in the place without invasion of rain and snow;

1.10 Operation conditions:

1.10.1 The ambient air temperature shall be from -30ºC to +70ºC (derate when the temperature exceeds; see the technical

materials in the sample for details);

1.10.2 The characteristic shall not be affected when the altitude is 2,000m (derate when above 2,000 m; see the technical

materials in the sample for details);

1.10.3 The ambient air temperature for storage shall be -40ºC- +75ºC.

1.11 The protection grade of the product body is IP20

1.12 Cabinet door installation

1.12.1 With toggle handle: Protection grade is IP40.

1.12.2 With rotation handle: Protection grade is IP50.

1.12.3 With motor-operated mechanism: Protection grade is IP40
