H2015B-3 - Eaton Thermal Unit

Protect your motor control circuits with confidence using the H2015B‑3 Heater Pack, a dependable thermal overload element designed specifically for use in motor starters and control systems. This well‑engineered unit steps in to guard your motors from overcurrent or sustained overloads, minimizing risk of damage and reducing downtime. Compact yet capable, the H2015B‑3 fits neatly into tight enclosures while delivering the performance needed in demanding setups. When you install one, you’re not just adding a component—you’re reinforcing reliability.

Key Features and Benefits

• Precise Overload Protection: The H2015B‑3 is built to detect and respond to overcurrent conditions accurately, safeguarding the motor windings, control cabling, and downstream equipment.
• Wide Operating Range: Rated for 29 A to 44.1 A full‑load current, this unit covers a useful span of motor sizes and allows flexibility in system design.
• Standard Class 20 Trip Curve: Uses a standard trip characteristic to coordinate well with other protection devices, reducing nuisance trips while ensuring safety.
• Space‑Efficient Design: With compact dimensions (~1.7" W × 3.1" H × 1.8" D) (43 mm × 79 mm × 46 mm approximate), it’s ideal for tight control panel layouts.
• Easy Integration: Built for backward compatibility with NEMA / IEC starter systems. If upgrading older setups, it can replace legacy heating elements with minimal rework.
• Durable Operation: Rated to resist vibration, temperature fluctuations, and repeated cycling, this heater pack holds up under continuous use in industrial settings.
• Certified Safety: UL and CSA listings (as a heater accessory) provide assurance of safety and compliance in control panels.

Material Compliance and Certifications

• Every H2015B‑3 unit is built in adherence to strict safety and environmental standards. It meets or surpasses UL and CSA certification standards for heater and motor control accessories. The materials used—both metallic and insulating—are chosen for stability under heat, vibration, and long service life. In jurisdictions where RoHS or similar regulations apply, the unit conforms to those limits (free from excessive lead, mercury, or cadmium). Wherever applicable, it’s also tested for electromagnetic compatibility and safe operation in industrial control environments.

Where It Works Best

• This heater pack is ideal in motor control panels where thermal overload protection is crucial—think pumps, compressors, conveyors, HVAC systems, and general industrial drives. Because of its compact size, it’s especially suited to control enclosures or retrofits where space is limited. Use it in manufacturing plants, process control rooms, water treatment facilities, or any setting where consistent, dependable motor protection is a must. If your system demands a heater element that can stand up to repeated cycles, harsh conditions, and precise coordination with other protective gear, the H2015B‑3 is a smart choice.
