Power Relays, Over 2 Amps

The 3100-30I17999AT is a power relay that allows for switching circuits on and off at greater than 2 amps. It is a latching type of relay that works on a minimum coil voltage of 12 V AC or DC, but is able to work at voltages up to 48 V AC or DC. The 3100-30I17999AT has a contact configuration of 3 poles, with one normally open contact and two change-over contacts.

Application Field

The 3100-30I17999AT is a versatile power relay designed for a variety of applications. Its general purpose and practical housing enable it to be used in home, commercial, and industrial environments. This power relay is well-suited for general purpose control applications, such as switching motors, lights, pumps, and similar equipment. Many variations in contact configurations and voltages, as well as different operational characteristics make it a suitable solution for many industries. In particular, this power relay can also be used to switch multiple circuits in alternative energy systems, such as solar power, wind power, and hydroelectric energy.

Working Principle

The 3100-30I17999AT operates according to the principle of electromagnetic attraction to switch on and off circuits with greater than 2 amps of current. When an electric current passes through the coils of the power relay, an electromagnetic field is created. This electromagnetic field attracts the armature within the relay, a very strong piece of metal that is shaped like an "L". When the armature is attracted, the iron core of the armature is magnetized. This magnetism is then transferred to the contacts, thus changing the position of the contacts and switching the circuits on and off.

When the power is turned off, the electromagnetic field collapses, resulting in the armature becoming de-energized. This reverses the process, thus switching the circuits off. In this way, the 3100-30I17999AT’s latching action allows it to switch more than 2 amps of current on and off without the need for constant energy input.

Conclusion

The 3100-30I17999AT is a powerful power relay with numerous applications, particularly in the field of alternative energy systems. It is capable of switching well over 2 amps of current with its latching-type action. This power relay has a coil voltage range from 12 to 48 V AC and DC, and a contact configuration of 3 poles, with one normally open contact and two change-over contacts. It is generally used for control applications, such as switching motor, pumps, and lighting.
