Renewable Design for Fingerprint Scanner - TZN63 (TVBM7)-12 Side-mounted indoor high voltage vacuum circuit breaker – TENPRO

Outline

TZN63 (TVBM7) – 12 type side-mounted indoor high-voltage vacuum circuit breaker is an indoor AC high voltage switchgear. It is suitable for three phase power system with rated voltage of 12 kV and frequency of 50Hz. It is used as protection and control appliance because of the special superiority of vacuum circuit breaker. It is especially suitable for frequent operation under rated current or multiple short circuit current switching.

Side – mounted vacuum circuit breaker of TZN63 (TVBM7) -12 is fixed installation, and is mainly used in fixed switchgear. The circuit breaker can be used either alone or in loop power supply, box transformer or various non-standard power supply systems.

This circuit breaker complies with domestic and international standards such as GB 1984 – 2003, GB / T11022 – 1999, DL / T403 – 2001, IEC62271 – 100: 2003.

Regular service conditions

1、Ambient air temperature: the upper limit is +40 C, the lower limit is -15 C.

2、The altitude is less than 1000m (if the elevation needs to be increased, the rated level should be raised accordingly).

3、Amplitude: seismic intensity does not exceed 8 degrees.

4、The daily average of air relative humidity is not greater than 95 and the monthly average is not greater than 90.

5、No fire, explosion risk, serious pollution, chemical corrosion severe vibration site.
