LZ-15-5 C15 Vacuum cleaner socket

The LZ-15-5 is a specialized power inlet socket designed for vacuum cleaners and other high-heat generating appliances. It is built to the IEC 60320 C15 standard, featuring a three-pin configuration with a distinctive keyway notch at 120 degrees. The critical distinction from the common C13 inlet is its higher temperature rating; the C15 socket is rated for operation at 120°C, compared to the C13’s 70°C. This makes it the mandatory and safe choice for connecting the power cord to vacuum cleaners, where the motor and internal components generate significant operational heat.

This inlet is engineered for direct panel mounting on the vacuum cleaner’s main body. It provides a secure and standardized point to attach a detachable C14-to-wall plug power cord. The socket’s robust construction, typically using high-temperature, flame-retardant thermoplastics (UL94V-0), ensures durability against the physical stresses of regular cord insertion/removal and the thermal stresses of continuous operation. The contacts are designed for reliable conductivity under load, minimizing resistance and voltage drop.

For the vacuum cleaner industry, compliance with international safety standards is non-negotiable. The LZ-15-5 is therefore developed and certified to meet key approvals such as UL, cUL (for North America), and CE (for Europe). These certifications verify that the component passes rigorous tests for electrical safety, mechanical endurance, and heat resistance according to appliance-specific standards (e.g., UL 60320, EN 60320). By integrating this certified C15 inlet, manufacturers ensure their vacuum cleaners have a safe, reliable, and globally recognized power connection that mitigates the risk of overheating at the connection point, a crucial factor for both household and commercial cleaning appliances.
