SEO Main Description Paragraph

The Allen‑Bradley 140M-I8E-D10E is a robust I-frame three-pole motor protection circuit breaker designed to safeguard medium-current industrial three-phase motors. This 140M-I8E-D10E unit features an adjustable thermal trip spanning 80A to 100A paired with fixed 13×In instantaneous magnetic short-circuit trip, delivering reliable Class 10 overload protection to avoid motor burnout during heavy load fluctuations. Complying with global UL and IEC industrial safety standards, the 140M-I8E-D10E provides high short-circuit interrupt capacity to stabilize motor control center operation under power fault conditions. Pre-equipped with stainless steel terminal lugs simplifies fast field wiring for maintenance engineers and automation integrators. Every Allen‑Bradley 140M-I8E-D10E undergoes complete overload and short-circuit function testing prior to shipment, supported by instant spot stock and long-term warranty to cut equipment downtime for factory motor control cabinet retrofits and spare part replacement.
