Field Introduction
Found this slugger in a glass-door Coca-Cola merchandiser or a heavy-duty sandwich prep table? You are looking at the Emerson Copeland KCE444HAG. This 3/8 HP unit is a cast-iron workhorse built to handle the constant door-opening abuse of commercial beverage coolers. When a shop owner relies on cold drinks to keep the lights on, this HBP (High Back Pressure) compressor does the heavy lifting. It runs smoothly on R-134a, but when it finally locks up or burns out a winding, you need the hard numbers to wire it back up or drop in a reliable match. Let’s break down the specs.

Technical Specifications Table
Knowing what the compressor is doing on the inside dictates how you size the metering device and handle the system charge.
| Specification | Value |
| Horsepower (HP) | 3/8 HP |
| Displacement | 12.05 cc |
| Cooling Capacity (HBP) | ~3675 BTU/h / 1077 Watts |
| Application Type | HBP / CBP (High / Commercial Back Pressure) |
| Operating Voltage | 230V |
| Motor Type | CSCR (Capacitor Start, Capacitor Run) |
| Max Continuous Current (MCC) | 3.0 A |
| Rated Load Amps (RLA) | ~2.2 A (at HBP standard conditions) |
Electrical & Origin Details
Wiring up a CSCR motor means you are dealing with potential relays and dual capacitors. Don’t mix up your start and run values, or you will bake the new start winding before lunch.
- Motor Circuit: CSCR (Capacitor Start, Capacitor Run) for high starting torque.
- Start Capacitor: 40-60 µF @ 230 V AC (Gets the heavy rotor moving against high head pressure).
- Run Capacitor: 10 µF @ 440 V AC (Keeps the power factor tight and the motor running cool).
- Relay Model: KARPN-4241 (Potential Relay).
- Overload Protector (OLP): KAT0072/H3 or MRA-12309-12101.
- Manufactured By: Emerson Climate Technologies (India) Limited.
Efficiency Metrics Table
Here is how the KCE444HAG pulls down at varying evaporator temperatures (assuming a standard 130°F / 54.4°C condensing temp):
| Evaporating Temp (°F / °C) | Cooling Capacity (BTU/h) | Power Input (Watts) | Amp Draw |
| 45°F / 7.2°C (HBP) | 3675 | 475 | 2.2 |
| 20°F / -6.7°C (CBP) | 1880 | 339 | 1.64 |
| 0°F / -17.8°C | 1190 | 268 | 1.33 |
Drop-in Replacements
If you can’t source a fresh Copeland KCE444HAG from the supply house, these 3/8 HP, ~12cc, R-134a HBP models will bolt right in and keep the cabinet at temp:
This is exactly the kind of comprehensive information I’ve been looking for. The way you explained the core concepts makes it very easy to follow, even for those who aren’t experts in the field.
This is a keeper.
Sharing this with my friends.
Thanks for existing, seriously.
Wish I found this earlier.
Not too long, not too short. Just right.
Already sent this to my group chat.

Excellent breakdown of the topic. You managed to cover the basics without getting too bogged down in the weeds, which is rare to find in technical blogs these days.
