Electronic Start Relay.3-wire.120V / 127V AC.1/4 HP to 1/3 HP.SNR-013-1.
This device is an SNR-013-1 Electronic Start Relay, a specialized “3-in-1” combination starter designed for refrigeration compressors. used as a universal replacement for original compressor starting components.
Core Specifications
- Part Number: SNR-013-1.
- Voltage: Rated for 120V / 127V AC systems.
- Compatibility: Designed for compressors with a horsepower (HP) rating of 1/4 HP to 1/3 HP.
- Type: 3-wire electronic relay.
Key Functions & Features
This unit is a “3-in-1” device because it integrates three critical components into a single housing:
- Start Relay: Momentarily connects the compressor’s start winding to provide the torque needed to begin rotation.
- Overload Protector: A safety feature that automatically cuts power if the compressor draws excessive current or overheats, preventing motor burnout.
- Internal Start Capacitor: Provides an extra electrical “boost” (hard start) to help older or “stuck” compressors kick on.
Wiring Overview
The 3-wire configuration is designed to connect directly to the three pins on a standard refrigeration compressor (Common, Start, and Run):
- Black Wire: Typically connects to the Common (C) terminal.
- White & Red Wires: Typically connect to the Start (S) and Run (R) terminals.
- Connectors: The pre-installed female spade connectors allow for a simple “plug-and-play” installation without specialized tools.
