Power relays, differing from standard relays, are tailored to handle environments where they must endure long periods of time without overheating, and to be able to work with much higher currents of load. An example of this is the 1617787, a relay that is capable of over 2 amps of current. In order to understand the working principles and applications of this power relay, we need to know a few different aspects.

The Components of the 1617787

The 1617787 is a metal enclosed control relay with a built in thermal may to protect it from high-temperature damage. It contains a 3-pole double-break contact system giving it a maximum control current of 15 Amps and its dielectric strength is one and a half times the control current. Its terminals are silver plated brass and its dimensions are 195x56x82mm.

Applications of the 1617787

The 1617787 is most commonly used in industrial or commercial applications such as conveyor systems, wet processes, cranes and elevators, pump controls, motor starters, and temperature/humidity sensing. It is highly reliable with a maximum switching capability of approximately 20 million and can be used in vacuum areas. It can also be used for power distribution or motor control panels.

Working Principles of the 1617787

The 1617787 relay works on a start/stop principle. When the start input is initiated, the relay contacts move to the “on” position, which allows the current to pass through. This then acts as a signal to the device connected to the relay that it should start running. When the stop input is initiated, the relay contacts move to the “off” position, which interrupts the current flow and acts as a signal to the device connected to the relay that it should stop running.When these two actions occur, the normally open contact is in the “on” position and the normally closed contact is in the “off” position. When the permanent magnet, which is the relay coil, is energized, the armature moves, and the contacts move to the “on” position. Conversely, when the magnet is de-energized, the armature is released, and the contacts move to the “off” position.

Benefits of the 1617787

The 1617787 relay is a power relay that is designed for both industrial and commercial applications. It is highly reliable with a switching capability of over 20 million volts and is able to withstand extreme temperature and vibration conditions. Its 3-pole double-break contact system permits maximum current ratings of 15 Amps and its dielectric strength is 1 and a half times this amount. Its terminals are also silver plated brass, and its compact size makes its ideal for installations in tight spaces. Moreover, it is easy to install and maintain, making it a great choice for many applications.

Conclusion

The 1617787 is an ideal choice for power relay applications, due to its reliability, compact size, and its ability to withstand extreme temperature and vibration conditions. It works on the start/stop principle, where input initiation causes the contacts to either open or close in order to transmit a signal to the device connected to the relay. Its silver-plated brass terminals and 3-pole double-break contact system give it a maximum current rating of 15 Amps, and its dielectric strength is 1 and a half times this amount. It is most commonly used for conveyor systems, wet processes, cranes and elevators, pump controls, motor starters, and temperature/humidity sensing, and has the ability to handle up to 20 million switching operations.
