The 1181511001 is one of the most common power relays, exceeding 2 amps in current-handling capability. It’s commonly used in a variety of industrial, commercial, and residential applications. This article will discuss the application field and working principle of the 1181511001.

Application Field

The 1181511001 is used for a variety of applications, including switching high-voltage power in electric motor controls, sound and alarm systems, HVAC systems, and lighting systems. In addition, it is used in rooftop and street lighting control systems, and security monitoring systems. It is also used in electrical switch gear, elevators, automatic vending machines, and even consumer electronics.

The 1181511001 is highly recommended for applications that require high reliability and dependability due to its high contact ratings and initial contact resistance values. In addition, its standard design makes it suitable for a wide range of applications.

Working Principle

The 1181511001 is a latching power relay. This means that once it is triggered, the relay stays in its “on” state until de-energized by a second set of contacts. The latching action occurs when current is passed through its coil, which then closes its set of control contacts. This energizes its internal coil, which then causes the switch contacts to close and the circuit is completed.

The coil is made up of a ferromagnetic core, which is surrounded by a soft-iron core and an armature. When a current passes through the coil, it generates a magnetic field that causes the armature to move to a certain point. This motion of the armature then causes the contacts to close, completing the circuit. The contacts remain closed until the current to the coil is cut off, at which point they reset and re-open.

In addition, the 1181511001 also features several design features that meet industry standards for safety and reliability. For example, its metal clad housing is designed to protect against dust and moisture, while its corrosion-resistant contacts ensure high contact reliability. Furthermore, its wide contact gap ensures a reliable switching capability and efficient operation.

In conclusion, the 1181511001 is an industrial-grade latching power relay. It is used for a variety of applications where safety and reliability are important, such as motor control, HVAC systems, and security monitoring systems. Its design features ensure a reliable switching capability, and its metal clad housing provides protection against dust and moisture. The working principle of the 1181511001 is based on a coil that generates a magnetic field and causes a set of contacts to close or open when energized or de-energized.
