Description
Refrigerator Compressor Start Relay Atlant NH 14 (1/4 HP, 185W, 1.3A)
Original combined start relay Atlant NH 14 is designed to start single-phase asynchronous motor-compressors of domestic refrigerators and freezers with a power of 1/4 HP (about 185 W), as well as for their comprehensive protection against current and thermal overloads. The design combines a starting electromagnetic current relay and a thermal protection relay (disc type) in a single unit. The unit briefly connects the starting winding of the electric motor at the moment of start, and in the event of a rotor stall, emergency voltage drop, or inter-turn short circuit, the bimetallic plate instantly opens the power circuit, preventing the compressor stator windings from burning out.
Key advantages and features:
- Combined start-protection design: Combines the functions of phase-shifting start and automatic emergency thermal-current shutdown of the compressor in one compact housing.
- Precise electrical parameters (1.3 A / 9 A): Designed strictly for a rated operating current of 1.3 A and a starting current of up to 9 A, which ensures standard starting of a 185 W (1/4 HP) motor without false protection trips.
- Compressor protection against overheating and voltage drops: A sensitive bimetallic element protects the electric motor from overheating during difficult starts under pressure or at high ambient temperatures.
- Direct mounting on feed-through terminals: Installs directly onto the pin terminals of the hermetic compressor, ensuring reliable contact without intermediate wires.
- Standard Faston blade terminals: Connection of external thermostat and mains cables is carried out via reliable 6.3 mm wide flat terminals.
Compatibility and scope of application:
Standardly used with compressors from the Baranovichi Machine Tool Plant (CJSC "Atlant") of the СК, СКО, С-КН series with a power of 160–185 W (e.g., СКО-160, СК-175, СКО-175, СК-200), and is also compatible with Jiaxipera, Secop, ACC, Donper compressors of the corresponding power (1/4 HP):
- Atlant / Minsk refrigerators: most two-compartment and single-compartment models of the МХМ, ХМ series (МХМ-1704, МХМ-1843, ХМ-6021, ХМ-6024, МХМ-2835, МХМ-2706, etc.).
- Stinol: models 101, 102, 103, 104, 107, 110, 116, 117 (when installing СК/СКО 1/4 HP compressors).
- Indesit, Ariston, Hotpoint: models with Atlant СКО compressors with a power of about 180–185 W.
- Nord, Biryusa, Dnepr, Pozis, Snaige: domestic refrigerators and freezers with 1/4 HP motors and an operating current of 1.3 A.
- Interchangeable analogs and factory codes: Atlant NH 14, РКТ-2, РКТ-3, Р-3, Р-4, ZHB60-120P15.
