Understanding the key to smart and magnetic relays

Magnetic relay is used to control the flow, the relay principle is based on magnetic phenomena.

A short circuit in such a situation can not be so quick disconnect relay time (thermal) used for the heating of the bimetal relay requires a relatively long time.

thermal relays are used.

Signal lamps

The disadvantage of the device and show.

Lights used in the control circuit, a low-power lights (2/1 to 5 Watts) with different voltages from 24 to 220 volts, the lights are working in three standard colors red, green and orange can be made.

green light to the display mode can be turned off at the circuit maps are used to display the signal lights of the letter h.

Fuses

Various protective gear used. These vehicles shall be selected as a result of overload or short circuit in the shortest time possible, before damage to the wires and electrical network, network reach, cut off the damaged part of the circuit.

Steep fuse time off work and that is why less than fuses are used in lighting applications. The fuse of a time off work longer Hstnnd and thus to start electric motors are used.

Fuse cartridge type, automatic (alpha), miniature boxes, knives (blade), glass or cartridge and high voltage fuses are made.

Fuses commonly used in the power circuit, contactor circuit protects against short circuits, ie the interface protection circuit wires on the 25 amp fuse Therefore the circuits that are used, for example, may the control circuit of wires or one and a half to be Shvd.ps control circuit with separate fuse protection.

Some of the automatic fuses two high current operation and high load

in the control circuit, but after the failure, must press the button again so quickly connected to the circuit.

The automatic fuse two elements are magnetic and thermal magnetic field and the high current short circuit or thermal (bimetal) high load (continuous flow) is cut.

Key miniature dishes that fuse an internal structure similar to fuse the alpha and the three magnetic relay (relay fast, high current), thermal relays or bimetal relay (high current relay delay) and the key to this collection are made Key Namnd.ayn engine keys in L-type and G type L made applications and harsh lighting is used (LIGHT) and type G in the motor vehicles used and the start is The key in all kinds of single phase and three phase two can be made.

Understanding the control circuit

Control circuit (2)

Contactors for AC and DC currents made Myshvd.tfavt the contactors of AC contactor is in a short-circuit loop to prevent the vibration frequency of the electricity used.

Various devices used in electrical circuits of the most important use of the contactor magnetic contactor or switch control circuit creates a variety of different designs.

Means that the circuits are used in the following command:
