Circuit breakers

Automatic circuit-breakers for motor protection

To protect the power circuit of the electric motor used Electromechanical devices-the machines of protection. They are able to protect the motor from short-circuit, overload or phase failure.
the Process of protection takes place without the use of fuses, that saves money. Automatic engine protection fast enough to operate at the circuit and immediately shut down the engine.

Advantages

• the Presence of additional elements;
• Compact size.
• Easy installation;
• reduce the possible downtime due to the high degree of protection of the engine;
• Reduction of maintenance costs due to the fact that the engine reliable protection.

the Possibilities of machine protection

• Helps to maintain the efficiency of the motor against short circuits and overloads by means of manual control;
• Protection capable of handling the current from overload and triggered readout of trip;
• Has a mute function;
• In the presence of temperature compensation;
• Makes it possible to remote control;
• Can be switched off with the closure of the Ics up to 100 kA.

the Device of automatic protection of engine often used in businesses and industrial facilities. With their help control operation of the engine, and also protect them from overload and short circuit.
For extra protection cabinets with hardware companies use switches door protective. These switches help to monitor door status and to implement the door lock.


Settings for options.
For an accurate and timely response and protection to the engine need to carefully select switch on the following parameters:

• rated current for tripping of the thermal protection (1 to 80 A). You need to choose with a nominal current that exceeds the motor current 1.2 times.
• the Ability to turn off shows at what value of fault current will trip. This is usually 50 or 100 kA.
• Setting magnetic trip units must be greater than the rated current (from 13 to 138 A). This indicator shows the minimum value of the current in the circuit, which triggered the circuit breakers to start the engine.
• Degree of ingress protection is indicated by the figures after the letters IP. The first digit reflects the level of protection from dust and foreign objects and the second against moisture.

Automatic engine protection help prevent serious problems that prevent the consequences from short-circuiting or overheating. The modern way to protect expensive equipment.
