Power relays are electric switches used for the control and switching of high-voltage power systems. The KUL-11D55D-12 is a power relay designed to handle currents of over 2 amps. It is a small form factor device, measuring 0.3 inches by 0.5 inches by 0.15 inches.

The KUL-11D55D-12 is an AC-powered non-latching relay with a DC coil voltage rating of 35 volts DC and a rated load current of 11 amps. The device is offered in a range of contact configurations, including SPDT (single pole double throw) and SPST (single pole single throw). The contact rating is 10A/250VAC for both make and break contacts.

The KUL-11D55D-12 is well-suited for use in lighting, motor control, and other applications requiring high-current switching. Its small size makes it a great choice for space-constrained applications. The device is also designed for reliable operation in high-noise environments, with an immunity level of 0.15 volts 1kHz.

The device has several features that reduce the risk of failure. For instance, it has a high electrical life, rated at over one million operations. Additionally, it features high contact reliability, with low contact resistance. The KUL-11D55D-12 is also capable of operating in temperatures between -40°C and +85°C.

The KUL-11D55D-12 operates via the principle of magnetically induced contacts. When a DC voltage is applied to its coil, it generates a magnetic field that causes the contacts to be drawn together, forming a closed circuit. When the coil is de-energized, the contacts open, breaking the circuit.

This principle is used in a range of applications, including motor control, lighting control, HVAC systems, building automation, and many others. In motor control applications, the KUL-11D55D-12 is often used to control and switch the flow of high-current energy to the motor\'s winding in order to move it. Similarly, in lighting control applications, the device can be used to switch high-voltage power to the lights in order to turn them on and off.

In addition to its primary power switching applications, the KUL-11D55D-12 is often integrated into circuits as a safety switch. The device can be used to disconnect power from a circuit if certain parameters are exceeded or if a circuit fault is detected. This can help to reduce the risk of damage to equipment if abnormal conditions occur.

The KUL-11D55D-12 is a robust power switch designed for applications requiring reliable high-current switching. It has a low profile, excellent electrical life, and resistance to high-noise environments. The device also offers features such as high contact reliability and a wide operating temperature range. Its magnetically induced contact principle makes it an ideal choice for motor control, lighting control, and other applications.
