Power Relays, Over 2 Amps

The APF10306 is a power relay designed to control high current electrical circuits. It can handle currents up to 20 Amp, making it suitable for many industrial applications. It has a standard DIN mounting clip and can be mounted to any standard cabinet or panel.

The APF10306 uses a single-pole double-throw (SPDT) type contact configuration. This means it can be wired to operate as either an on/off relay switch or as a two-speed relay switch. In either mode, when the circuit is energized, the relay opens or closes the contacts, depending on its configuration.

The APF10306 has two separate configuration options: the first is an internal configuration and the second is an external configuration. In the internal configuration, the first two contacts of the relay are shorted and the third contact is normally open. When the relay is energized, the first two contacts close, and the third contact opens. In the external configuration, the first two contacts of the relay are open and the third contact is normally closed. When the relay is energized, the first two contacts open, and the third contact closes.

The APF10306 is typically used in industrial applications where high currents are required, such as lighting or motor controls. It can also be used in medical applications, such as defibrillators, or in electrical systems for safety or comfort applications.

The APF10306 can also be used to provide a safety circuit for vehicles or other motorized equipment to protect against accidental reverse polarity of the power supply. In this configuration, the relay would remain open when the battery is connected in reverse polarity, preventing hazardous voltage from being applied to the equipment.

The working principle of the APF10306 is simple. When power is applied to the coil, it creates a magnetic field which attracts the plunger and opens or closes the contacts, depending on its configuration. When the power is removed from the coil, the magnetic field collapses and the plunger returns to its original position, opening or closing the contacts as before.

The APF10306 is a reliable and durable contactor used to control high-power loads. With its ability to handle currents up to 20 Amp, it is suitable for many industrial applications. It is easy to install and can be configured in either an internal or external configuration.
