Power relays over the 2 amp mark offer powerful solutions for many engineering applications. The LY2ZF AC200/220 is a relay switch designed for the safe and reliable switching of high current loads. This type of power relay includes a contact block made of high-grade silver contact material that allows the solid-state switching of up to 220AAC (95V).

The LY2ZF AC200/220 has a built-in overload overload protection feature to protect against abnormal or dangerous operating conditions. It has a Dielectric Strength Class (DST) up to >1500VAC for 1min and uses separate Form A and Form C contact blocks, giving it additional flexibility. This power relay is designed for a variety of applications, including residential, commercial, and industrial.

The LY2ZF AC200/220 is designed to provide superior switching performance and can be used in applications from -40°F to +150°F (-25°C to +65°C). It has both standard and reverse operation functions and is rated for use on 120-220VAC (50/60 Hz) circuits. It is UL/CUL/ROHS approved and each unit includes a controlling terminal and manual reset.

The LY2ZF AC200/220 is also designed with a low-leakage design and contact arc suppression feature. The special arc-breaking mechanism, short turn off time, and heated-air tunnel heat treatment (with optional filter) ensure excellent power relay lifetime performance and improved safety.

The LY2ZF AC200/220 power relay is well-suited for applications with high inrush currents, such as motors and compressors, as well as applications with large power ratings, such as AC/DC power supplies. It is also typically used in automatic equipment control, HVAC systems, electric ovens, heaters, and other applications where high power loads are switched.

The working principle of the LY2ZF AC200/220 power relay is based on the dual-coil design that consists of two electromagnets with different coil voltages and on-time RMS values. When the coil voltage of one of the electromagnets is reduced, the switch is switched off and the coil voltage of the other electromagnet is increased to take up the contact control. The on-time RMS value has an effect on the switching off time and thus on the service life of the relay.

The LY2ZF AC200/220 power relay is a reliable and cost-effective high-strength solution for many high power applications. It offers a robust design that is capable of operating under extreme temperatures and conditions, as well as providing overload protection and arc suppression. This type of power relay is designed to provide reliable and safe switching and offers superior performance in many engineering applications.
