Power relays are essential accessories for many electrical systems and installations but they are often overlooked in favor of more complex solutions. When designing an electrical system it pays to ensure the correct selection of power relays, particularly those rated over 2 amps. The APF10348 is one such high-power relay, capable of handling in excess of 2 amps of current. In this article we will explore its application field and working principle.

The APF10348 is a three-pole all-mechanical power relay. It features heavy-duty construction with a rugged outer case that provides protection from moisture and dust while allowing for sufficient heat dissipation. The contact pins are silver-plated and rated for 2A at 30VDC or 2AB at 250VAC. The APF10348 has a mechanical durability rating of up to 20,000 operations at 120V and 10,000 operations at 250V. The dielectric strength is up to 4,000VAC. It has a high current capacity and can handle up to 16A of continuous current.

The APF10348 is an ideal accessory for many types of automated systems and applications. It can be mounted onto any type of enclosure or printed circuit board, making it a versatile choice for many modern industrial and commercial applications. It is particularly well-suited for applications that require high power handling as well as long service life. Examples include certain HVAC systems, motors, pumps, controllers, solenoids, and other industrial machinery.

The working principle of the APF10348 is fairly simple. It is triggered by a switch or other control signal. When the switch is activated, an electromagnet is energized, which in turn activates a latch that closes the contact between the two mechanical poles. The contacts remain closed as long as the switch is held in the "on" position. When the switch is released or the current is cut off, the electromagnet is de-energized, resulting in the latch being released and the contacts opening.

The APF10348 is highly reliable and capable of withstanding extreme temperatures. Its reliable performance makes it suitable for a variety of industrial and commercial applications, such as AC motor speed control, power adapters, UPS systems, lighting systems, and electromechanical relays. It is also suitable for both high voltage and low voltage applications, further increasing its versatility.

In conclusion, the APF10348 is a versatile and reliable power relay suitable for a variety of applications that require high power handling. It features heavy-duty construction with silver-plated contacts that are rated for 2A at 30VDC or 2AB at 250VAC. It is particularly well-suited for applications that require high power handling as well as long service life, such as for AC motor speed control, power adapters, UPS systems, lighting systems, and electromechanical relays. Its simple working principle consists of closing and opening the contacts via an electromagnet.
