Power Relays, Over 2 Amps

2912303 power relays are designed to switch large amounts of electrical current in an application where an electromagnetic switch or a mechanical switch is required. To achieve this, the 2912303 power relays have a strong electromagnet and a bimetal-activated switch (known as a switch arm) which operates when current passes between these two components. The power relays have a contact configuration which allows them to be used in AC as well as DC circuits.

When power is applied to the electromagnet of the 2912303 power relays, it creates a magnetic field which pulls on the switch arm and causes it to move and switch on the relay. Due to the large amount of current switching, the electromagnet must be powerful enough to move the switch arm with relative ease. When the power is removed from the electromagnet, the magnetic field dissipates and the switch arm returns to its original position.

The 2912303 power relays also feature a protecting contact, which is designed to keep the load connected even if the relay contact fails. This additional protection helps reduce the risk of faults due to contact wear or debris in the system. In addition, the contact system is designed to be redundant, in the case of an overload or short-circuit condition, the contact which is not involved in the overload will remain engaged.

The 2912303 power relays are suitable for a wide range of applications such as motors, magnets, transformers, and lights. The power relay can also be used in circuits where a controlling device requires a large amount of power to be switched on and off rapidly. The high-powered electromagnets in the power relays make them ideal for switch-on applications which require quick response times. The power relays can also be used for a variety of other purposes, such as providing a fast-acting device to disconnect a circuit in case of an overcurrent situation.

The 2912303 power relays are designed to meet the requirements of UL and CSA standards. As such, they come with an easy-to-install terminal arrangement, are shock and vibration resistant, and are highly repeatable and reliable. Furthermore, the power relays are available in a wide range of voltage and current ratings and generally come with a variety of additional features such as multiple pole configurations and thermal overload protection.

Overall, the 2912303 power relays are robust and reliable electromechanical switching devices which are suitable for a wide range of applications. They are designed to stand up to a variety of conditions and are capable of switching large amounts of current. In addition, the power relays come with a range of features which make them suitable for many different applications.
