Allen-Bradley 140M-C2E-B16 - 6 A, 3-Pole Circuit Breaker | AmpState

The Allen-Bradley 140M-C2E-B16 is a compact, 6A three-pole molded case circuit breaker designed to deliver dependable branch circuit protection in panelboards and load centers. Built for steady performance in demanding electrical environments, it helps keep critical circuits safe from overcurrent and short-circuit events without sacrificing panel space or ease of maintenance.

Why this breaker stands out

• Space-efficient molded case design optimizes panel layouts, making it easier to fit into tight electrical cabinets and streamline installation.
• Thermal-magnetic trip unit provides stable, repeatable protection by sensibly responding to both overloads (thermal) and short circuits (magnetic), reducing nuisance trips while safeguarding equipment.
• OEM-compatible for seamless replacement and integration with matching load centers and panelboards, ensuring proper fit, performance, and coordination with existing systems.
• Broad application suitability ideal for residential, commercial, and light-industrial settings where reliable 3-phase protection is needed.
