Product Overview


The Miniature Intermediate Power Relay LY4 is a compact, versatile electrical component developed by CLION Electric (model: NNC68A), engineered to meet diverse power control needs across industries. Operating on the principle of electromagnetism, this relay features a core structure of a single coil, an armature, and precision contacts—when current flows through the coil, a magnetic field is generated to attract the armature, closing the contacts and enabling circuit control. What sets it apart is its 15A Switching Capacity, a key advantage that lets it handle demanding electrical loads, making it far more robust than standard low-power relays. As a Single Coil General Purpose Relay, it balances simplicity and performance, suitable for both industrial and commercial applications where reliability and space efficiency matter.

Key Features of the Miniature Intermediate Power Relay LY4


High Switching Capacity Up to 15A

At the heart of the LY4 Relay is its exceptional 15A Switching Capacity—a critical specification that allows it to manage high-power systems like industrial machinery motors, heavy-duty HVAC compressors, and large-scale lighting arrays. Unlike smaller relays that struggle with overloads, the CLION LY4 Relay maintains stable performance even in power-intensive scenarios, reducing the risk of contact wear or circuit failure.


Single Coil Design for Simplified Installation

The Single Coil Design of the Miniature Intermediate Power Relay LY4 is a game-changer for engineers and installers. It eliminates the complexity of dual-coil wiring, cutting down installation time and minimizing the chance of wiring errors. This design also reduces the relay’s overall footprint, making it easy to integrate into crowded circuit boards or tight equipment enclosures—ideal for projects where space is a constraint.


Compact Size with Durable Build

As a Compact Electromagnetic Relay, the LY4 measures just 27.3mm×41mm×35mm (per CLION’s technical specs) and weighs approximately 65g per unit. Despite its small size, it boasts a rugged construction: the Ag Alloy (AgSnO2) contacts resist corrosion and wear, ensuring a long electrical life of ≥1×10⁵ cycles and mechanical life of ≥1×10⁷ cycles. This durability makes it a cost-effective choice for long-term use.


General-Purpose Versatility Across Industries

Unlike application-specific relays, the General Purpose LY4 Relay adapts to diverse sectors. It works seamlessly in industrial control panels, consumer electronics (e.g., large appliances), automotive auxiliary systems (e.g., power windows), and even new energy setups (e.g., small-scale solar inverters). Its flexibility eliminates the need to stock multiple relay types, simplifying inventory management for businesses.


Energy Efficiency and Wide Voltage Compatibility

The CLION LY4 Relay prioritizes energy efficiency with a low coil power consumption: 1.5W for DC models and 3.0VA for AC models. It also supports broad voltage customization—coil voltages range from DC6V to DC220V and AC6V to AC380V—so it can integrate into global electrical systems without additional adapters. This compatibility is a key advantage for businesses operating in multiple regions.

Scenario-Based Solutions


Industrial Machinery Control

In manufacturing plants, Miniature Intermediate Power Relay LY4 is used to control motors, conveyors, and heating elements. For example, in a metal stamping machine, the relay’s 15A Switching Capacity handles the motor’s startup current, while its Single Coil Design ensures quick, error-free wiring during machine assembly. The relay’s ability to operate in temperatures from -40°C to 85°C also makes it suitable for harsh factory environments.


HVAC Systems Regulation

Heating, ventilation, and air conditioning (HVAC) systems rely on relays to switch compressors and fans. The CLION LY4 Relay’s 15A Switching Capacity manages the high current of HVAC compressors, and its energy-efficient coil reduces the system’s overall power usage. Additionally, its dielectric strength of 1500VAC between contacts and coil prevents electrical leaks, ensuring safe operation in residential and commercial buildings.


Automotive Auxiliary Systems

For automotive manufacturers, the Miniature Intermediate Power Relay LY4 is ideal for auxiliary functions like power windows, windshield wipers, and seat heaters. Its compact size fits into tight door panels or dashboard enclosures, and its shock resistance of 10G (11ms sinusoidal pulse) withstands vehicle vibrations. The Ag Alloy contacts also ensure reliable performance in extreme temperature changes, from cold winters to hot summers.


Consumer Electronics Power Management

In large consumer electronics—such as electric ovens, washing machines, or home theater amplifiers—the General Purpose LY4 Relay acts as a safety switch. It controls the flow of power to high-wattage components, preventing overloads. The relay’s low power consumption aligns with modern energy-efficiency standards, helping electronics meet global certifications like Energy Star.

FAQ


What is the maximum switching voltage of the CLION LY4 Relay?

The Miniature Intermediate Power Relay LY4 supports a maximum switching voltage of 240VAC (alternating current) or 28VDC (direct current)—a range that covers most industrial, commercial, and residential electrical systems. This voltage compatibility ensures it can be used in diverse applications without voltage-related issues.


Can the Single Coil General Purpose Relay be installed on both PCBs and DIN rails?

Yes. The LY4 Relay is designed for dual installation options: it can be soldered directly onto PCBs (printed circuit boards) for compact electronics or mounted via a socket onto DIN rails for industrial control panels. This flexibility makes it easy to integrate into different hardware setups.


What is the insulation resistance of the Miniature Intermediate Power Relay LY4?

The relay has an insulation resistance of ≥100MΩ (measured at 500VDC). This high resistance prevents electrical leakage between the contacts and coil, reducing the risk of short circuits and ensuring compliance with global safety standards (e.g., IEC, UL).
