H2005B-3 - Eaton Thermal Unit

H2005B-3 - Eaton Thermal Unit

For applications where space is tight and protection can’t be compromised, the H2005B‑3 motor control circuit breaker delivers dependable overload and short‑circuit protection for small motors. At just 2.50″ × 2.00″ × 2.00″, it’s built to fit compact control panels, while still offering solid protection against electrical faults. Whether you're installing into new machines or updating existing systems, the H2005B‑3 is a balanced, high‑value choice for safeguarding motors in industrial and commercial settings.

Key Features and Benefits

• Automatic Overload Protection: Trips precisely when a motor draws too much current, guarding both the motor windings and associated wiring.
• Short‑Circuit Defense: Instantly interrupts severe fault currents to protect downstream circuits.
• Compact Footprint: Its small dimensions make installation easier in panels with limited space.
• Stable Performance at 0.3 A: Consistent and predictable operation at its rated current helps reduce unexpected downtime.
• Straightforward Integration: Follows standard mounting and wiring conventions for ease of installation.
• Durable Construction: Built with materials resilient to vibration and thermal stress, so it holds up in demanding environments.
