Use of a steel core for installation of the relay of an overload in a starting position


The relay is electronically the operated switch which is usually used as follows:

– the relay can switch big currents remotely from a chain in which this current flows, allowing to use thinner wires and contacts of switches;
– the relay can have more than one managing director of an entrance unlike the mechanical switch;
– the relay can perform function of the timer, for example, to set an interval of work of screen wipers.

For protection of some electric chains (power windows, locks of doors, headlights) the overload relay is used. At considerable excess of the consumed current, the automatic relay of an overload for a short time will disconnect a power-supply circuit of the consumer, however for maintenance some relays of an overload need to be turned on manually. For this purpose remove the relay of an overload and from contacts insert a steel core into an opening of repeated installation and press a clamp before click (see rice. Use of a steel core for installation of the relay of an overload in a starting position).

If the system operated by the relay fails, and a cause of defect, perhaps, the relay is, listen to operation of the relay at the included system. If the relay regularly works, then you have to hear click at its inclusion. If the relay is serviceable, then the cause of defect is concluded in elements or the connecting wires. If the relay does not work, it means that it does not receive the main power supply or the operating impulse, or the relay is faulty.
