Coil Relay 1/5

Description

1/5 HP Refrigerator Compressor Coil Start Relay (Heavy Duty Mechanical Starter) ### Product Overview This Mechanical Coil Start Relay is a heavy-duty, electromechanical starter designed specifically for fractional horsepower refrigerator and freezer compressors (rated at 1/5 HP). Unlike modern solid-state PTC starters, a coil relay relies on an internal electromagnetic copper winding. When the refrigerator calls for cooling, the initial surge of current passes through this coil, instantly creating a magnetic field that pulls up a plunger to engage the compressor’s start winding. Once the motor reaches full speed, the current drops, the plunger falls via gravity, and the start winding safely disconnects—ensuring a powerful, high-torque startup every time. ### Key Features Electromechanical Reliability: Provides a mechanical snap-action connection, offering a robust alternative to temperature-sensitive PTC stone relays. Optimized for 1/5 HP: Calibrated with the exact coil resistance and pull-in/drop-out current needed to match standard 1/5 horsepower compressor motors. Premium Copper Windings: Built with high-purity, heat-resistant copper wire around the core for stable electromagnetic performance and longevity. Standard 2-Terminal or Push-On Setup: Features thick terminal flags for quick-connect spade terminals, allowing clean integration with matching thermal overload protectors. ### Product Compatibility & Cross-Referencing Coil start relays are highly standardized parts. To ensure compatibility, look for a match in horsepower rating (1/5 HP), operating voltage (typically 115V or 220V), and the pin configuration where the relay plugs onto the compressor terminals. Direct Replaces & Equivalent Parts: Appli Parts: APSR-151 (1/5 HP, 110V version) Supco / Smart Electric: SE1/5R Series (Push-On 1/5 HP mechanical starter) Embraco / Tecumseh / Danfoss equivalents: Often replaces older-style mechanical “hammer” or “bullet” style relays used on legacy fractional compressors (e.g., matching PW5.5A or EM45 series parameters). Compatible Appliance Types: Standard compact and mid-sized household refrigerators Single-door fresh food refrigerators Chest freezers and small upright deep freezers Beverage coolers, wine chillers, and commercial water dispensers Common Compatible Appliance Brands: Because it is a functional universal replacement component, it fits a wide spectrum of appliance brands utilizing a 1/5 HP compressor setup, including: Whirlpool / Kenmore / Maytag Frigidaire / Electrolux Danby Haier / Midea GE (General Electric) Galanz ⚠️ Installation Note: Mechanical coil relays are gravity-dependent. They must be installed right-side up (usually indicated by an arrow or text such as “TOP” marked on the casing) for the internal plunger to drop and disengage properly. Installing it upside down will burn out the compressor’s start winding.
