H2004B-3 - Eaton Thermal Unit

H2004B-3 - Eaton Thermal Unit

Take full command of your motor systems with the H2004B‑3 motor control circuit breaker. Engineered for dependable overload and short‑circuit protection, this thermal unit is ideal for industrial control panels, automation systems, and compact switchgear. Its balance of precision, space‑saving form factor, and safety features gives you confidence that your motors and control circuits are shielded from damage, without overcomplicating design or maintenance logistics.

Key Features & Benefits

• Accurate 0.3 A Overload Protection – Trips reliably under excessive current to guard motors, wiring, and control logic from overheating and fault damage.
• Compact Footprint – With dimensions of just 2.50″ H × 2.00″ W × 2.00″ D, it allows dense component layout in panels while maintaining access for servicing.
• Motor‑Control Friendly – Designed to tolerate startup currents (inrush) and frequent cycling, reducing nuisance trips during heavy use.
• Quick Maintenance & Replacement – The clear, consistent part number (H2004B‑3) and industry‑standard mounting make swap‑outs or upgrades fast and intuitive.
• Enhanced Safety Assurance – Built with fast tripping mechanisms to reduce risk of overheating, fire, or equipment damage under fault conditions.
