Introducing the genuine Allen-Bradley 140U-H2C3-C20-A 20A 3-Pole Circuit Breaker — a dependable safeguard for three-phase electrical systems. This is the exact replacement part you need to maintain performance and reliability in your control panels.

  • Part number: 140U-H2C3-C20-A — a precise, OEM-compatible component that ensures correct mounting, trip characteristics, and electrical fit.
  • Current rating: 20 amperes. This rating is ideal for protecting smaller to mid-sized three-phase circuits without nuisance tripping.
  • Poles: 3-pole design, providing balanced protection across all three phases and helping prevent phase-to-phase faults.
  • Trip performance: engineered to promptly interrupt power on overload or short-circuit events, protecting connected motors, drives, and control wiring.
  • Form factor: compact, panel-friendly profile that fits standard electrical enclosures used in industrial settings.
  • Application compatibility: designed for use in compatible Allen-Bradley panels and systems that specify the 140U-H2C3-C20-A family, ensuring consistent performance.

Where you’ll use it: in industrial control panels, motor control centers, HVAC equipment, conveyors, pumps, compressors, and any three-phase distribution that requires reliable overload protection.

Why this matters: a genuine Allen-Bradley circuit breaker with the exact trip curves and mounting geometry as your original equipment minimizes installation risk, maintains panel warranty alignment, and provides predictable protection across temperature and load variations.

Practical tips: before installing, verify the system voltage, compatible panel, and bus bar arrangement. Follow the enclosure manufacturer's torque specs and wiring diagrams, and replace only with a unit rated for the same voltage/current and for three-phase operation. If you’re replacing an older 140U-H2C3-C20-A, this part delivers a like-for-like fit and performance, so you can restore protection quickly and with confidence.

Order with confidence: this is a genuine Allen-Bradley 140U-H2C3-C20-A 20A 3-Pole Circuit Breaker, ready to protect and power your equipment.
