Scope of application

3TM1 series plastic freely shell type circuit breaker (hereinafter referred to as circuit breaker), is to adopt the international advanced design and manufacturing technology development, the development of one of the new type of circuit breaker. Its rated insulation voltage is 690 v, applied to ac 50 hz, rated voltage 400 v and below, and rated current under 800 a and do not frequent conversion circuit and the motor

Don't frequent starting, circuit breaker with overload, short circuit and low voltage protection device, can protect circuit and power equipment from being damaged.

Circuit breaker according to its rated short circuit breaking capacity limit (Icu) of high and low are divided into: type I (budget), M type (standard), H (high marks broken) three categories. The circuit breaker has small volume, high breaking, fly short arc, resistance to vibration, is an ideal product to land and Marine use.

• The breaker can be installed in vertical (i.e., vertical pack), can be installed horizontally (that is, the horizontal loading).

• The circuit breaker with isolation function

• The circuit breaker conforms to the standard: 12060947-2 and 0814048.2

Applicable to the work environment

• Altitude 2000 m and below;

• Surrounding medium temperature is not high in + 40 ˚ C (for Marine product + 45 ˚ C) and not less than 5 ˚ C. In high in + 40 ˚ C or below - 5 ˚ C under the conditions of use should negotiate with factory;

• Ability is affected by damp air;

• The influence of tolerated salt mist, oil mist;

• Ability under the influence of mold;

• Ability under the influence of nuclear irradiation;

• Maximum gradient is 22.5 °

• By shipping normal vibration can work reliably;

• Under the earthquake cases (4 g) can be reliable;

• In the absence of explosion danger of medium, and medium without enough to corrosive action on metals, and damage the insulation of conductive dust and gas;

• Where there is no rain and snow hit.
