H2023-3 - Eaton Thermal Unit

Need a dependable thermal unit that helps protect your motors and control gear without occupying too much panel space? The Eaton H2023‑3 heater unit delivers effective overload protection in a compact design. Engineered for motor starters and industrial control systems, it steps in quickly when currents rise above safe thresholds—shielding windings, shafts, and wiring—and helps reduce costly downtime. Whether you’re an electrical installer, OEM, or maintenance engineer, this unit gives you peace of mind through consistent performance and reliability.

Key Features and Benefits

• Compact but Capable: At just 3.2" high × 2.4" wide × 2.1" deep, the H2023‑3 installs easily even in densely packed control panels.
• Wide Full‑Load Range: Supports full‑load current settings from 84.7 A up to 115 A (dial positions A through D) to match a range of motor sizes.
• Standard‑Trip (Class 20): Delivers clear, predictable response under overload conditions, making coordination easier in multi‑motor systems.
• Easy Integration: Designed for use with Eaton Freedom NEMA size 3–4 and IEC L–N size starters—ideal for retrofits or new builds.
• Lower Thermal Stress: By preventing sustained overcurrent, it helps reduce heat buildup in motor circuits, contributing to longer service life.
• Time Savings on Installation: Dial adjustment, standard form factor, and predictable mounting make it faster to wire and test in control systems.
