Power Relays, Over 2 Amps

The LY4I4-AC100/110 is a power relay designed for power circuits that require more than 2 amps. This power relay is typically used in HVAC systems, industrial machinery and other larger applications. The relay’s design is capable of carrying a large load without compromising its protection features.The LY4I4-AC100/110 application field is broad and offers protection and control in variety of applications. This relay can be used in motor starters, contactors, overload protection devices and emergency motors. It can also be used to control and protect industrial pumps, compressors and conveyors.The relay features pluggable contacts which allow it to be customized to meet a variety of application needs. These contacts are easily replaced without the need to replace the entire relay and they also offer a means of isolating the relay from hazardous contacts. The contacts are additionally protected from arcing and other dangerous situations that could occur with standard contact designs.The LY4I4-AC100/110 is operated using a malfunction protector which is designed to detect abnormal currents and voltages in both the input and output circuits. This protector is designed to allow a current flow of up to 3.5 times the rated current through the relay, protecting it from damage caused by surges in the system. Additionally, the protector is designed to detect over-voltages and over-temperatures, shutting down the relay in these cases to prevent damage to the relay and surrounding components.The working principle of the LY4I4-AC100/110RELAY is relatively straightforward. When a power supply is connected to the relay’s coil, an electromagnet is energized. As a result, the contacts close or open depending on the coil current. When the coil is de-energized, the contacts return to their normal state. This allows the relay to control and protect the circuit it is attached to.The LY4I4-AC100/110RELAY is designed for use in AC circuits and features an operating voltage up to 110 volts. It is designed with a pre-load current rating of up to 100 amps and has a total operating current of up to 2.5 amps. The contacts have a maximum voltage rating up to 110 volts and the maximum resistive load allowed is 115 volts. Further, the maximum resistance allowed is 25 ohms, which allows the relay to accept a wide range of resistive loads.The LY4I4-AC100/110RELAY is a reliable and effective power relay designed to meet the demanding needs of large power circuits. Its pluggable contacts make it easy to replace and customize for a variety of applications, while its malfunction protector ensures that it is protected from dangerous currents and voltages. By combining these features, the LY4I4-AC100/110RELAY is one of the most reliable power relays designed for use over 2 amps.
