Power Relays, Over 2 Amps

The 44510-1250 relay is a power relay that is specifically designed to manage electrical loads that require more than 2 amps of power. This relay is commonly used in industrial and commercial applications where a large amount of power needs to be managed. It is a single-pole, double-throw (SPDT) device with a contact rating of 10A and a Voltage Rating of 250V AC.

The 44510-1250 features a number of different contact arrangements. It can be used in multiple pole applications to allow for the simultaneous switching of multiple circuits. It also has a 10 pin base which offers flexibility in the wiring of the circuit. Additionally, this relay has a built-in DIP switch which allows for the selection of different operating modes.

The 44510-1250 is designed to be used within a variety of different applications. It is commonly used in industrial automation, emergency lighting systems, HVAC systems, and many other types of control applications. It is also a popular choice for motor control as it is capable of handling high inrush currents and is considered to be a reliable device.

Working Principle of the 44510-1250

The basic premise of the 44510-1250 power relay is straightforward. In its simplest form, the device works by using an electromagnet to pull a switching arm between two contacts. Depending on the current that is applied to the electromagnet, it will cause the switching arm to move between open or closed positions. This allows for the control of different circuits.

The 44510-1250 uses a single coil to energize both switch and armature contacts. It has a built-in DIP switch which allows for the selection of different operating modes. These modes include timer, zero crossover, and hold mode. In the timer mode, the relay energizes for a selected time duration. In the zero-crossover mode, the relay energizes until the armature is released. And in the hold mode, the armature will remain energized even after the power is removed.

The 44510-1250 is equipped with various protection features to ensure long life and reliable operation. It is UL Listed Type 1 and Type 2 and has a surge protection rating of 250V AC. It is protected against overheating, overcurrent, transient voltage, and short circuit protection. Additionally, it is vibration-resistant and shock-resistant.
