Power Relays, Over 2 Amps

The PT370024 power relay is a high performance relay designed for applications which require high current capabilities and a reliable operation. It is often used for controlling large motors, pumps, and other industrial equipment.

This relay is designed from materials which have been carefully selected to ensure it will perform in a wide range of temperatures. Its plastic housing is designed to protect against dust, corrosion, and other environmental influences. Its contact system offers a long life with low contact resistance and high current capability.

Application Field

The PT370024 power relay is suitable for controlling motors, pumps, process equipment, and other electrical components in industrial and commercial applications. It can be used to replace contactors and other higher powered relays. This relay has two distinct operating ranges: one for applications that require high current and a separate range for low current applications.

Working Principle

The PT370024 power relay utilizes electromagnetic induction to control the flow of electricity. This principle is based on the fact that a varying current in one coil produces a varying magnetic field which, in turn, induces a current in a second coil. The current in the second coil can be used to control the flow of electricity in a circuit.

The PT370024 uses a dual-coil design to provide superior operational characteristics. The relay has a standard set of contacts which open and close depending on the current through the contact coils. When power is supplied to the contact coils, the relay’s contacts open and the relay is in its normally open position. When power is removed from the contact coils, the relay contacts close and the relay is in its normally closed position. The operation of the relay is reversible depending on the polarity of the voltage applied to the contact coils.

The PT370024 also provides additional features such as a built-in overload protection circuit. This circuit is designed to prevent the relay from being damaged by overcurrents. The overload protection circuit will activate if the current through the contact coils exceeds a set limit and will open the relay contacts until the current returns to a safe level.

In addition, the PT370024 is equipped with a safety feature that prevents the use of an external control voltage. This safety feature is designed to prevent unintentional operation of the relay. The safety feature can be enabled or disabled depending on the application.

The PT370024 is a reliable and durable power relay that is suitable for a wide range of applications. Its dual-coil design gives it superior operational characteristics while its overload protection and safety features ensure its reliable operation in harsh environments.
