Series Overview

Product Overview

The TGM1L series residual current operated circuit-breakers (hereinafter referred to as the circuit-breakers) are one of the new types of residual current circuit-breakers designed and developed using advanced international technology. They are suitable for circuits with an AC frequency of 50Hz, a rated voltage up to 400V, and a rated current from 16A to 800A.

• Their main function is to provide indirect contact protection against the fatal risk of electric shock to persons. Residual current circuit-breakers with a rated residual operating current not exceeding 30mA can also serve as supplementary protection for direct contact when other protective measures fail, but cannot be used as the sole means of direct contact protection. They can also be used to prevent fire hazards caused by earth fault currents. Furthermore, they can protect lines against overload, short-circuit, and other hazards, and can also be used for the infrequent switching of lines and the infrequent starting of motors.

• These circuit-breakers feature compact size, high breaking capacity, short arcing distance, and adjustable residual operating current and residual current operating time. They can be equipped with accessories such as alarm contacts, shunt releases, auxiliary contacts, rotary handle operating mechanisms, and electric operating mechanisms. They also support various wiring methods including front-mounting, rear-mounting, and plug-in type connection, making them an ideal product for users.

• Complies with standards: GB/T 14048.2 and IEC 60947-2.

### Normal Service and Mounting Conditions

• Ambient air temperature: Upper limit of ambient air temperature is +40°C; the average value over any 24-hour period shall not exceed +35°C.

• Altitude: The altitude at the installation site shall not exceed 2000m.

• Pollution degree: Degree 3.

• Installation category: III.

• Atmospheric conditions: The relative humidity of the atmosphere shall not exceed 50% at an ambient air temperature of +40°C; higher relative humidity is permissible at lower temperatures; the monthly average of the daily maximum relative humidity for the wettest month is 90%, while the monthly average of the daily minimum temperature for that same month is +25°C, taking into account condensation that may occur on the product surface due to temperature changes.

• External magnetic fields: The magnetic field at the circuit-breaker installation site in any direction shall not exceed 5 times the Earth's magnetic field.

• Mounting location: Install in a location free from impact, vibration, rain, and snow intrusion. The upper terminals connect to the power supply side, and the lower terminals connect to the load side. The circuit-breaker shall not be tilted more than 5° in any direction.
