EATON EMR‑3MP0‑2A0BB MOTOR PROTECTION RELAY WITH AMP GARD TERMINAL ADAPTOR – ROBUST MOTOR GUARDIAN FOR INDUSTRIAL APPLICATIONS
⚙️ The Eaton EMR‑3MP0‑2A0BB Motor Protection Relay is designed to guard three‑phase motors against overload, phase loss, and phase imbalance. It monitors motor current continuously and trips when current exceeds set limits. The relay combines thermal and magnetic trip functions in one unit for precise protection. It is paired with the AmpGard Terminal Adaptor (66C3515G01), which simplifies wiring and allows quick insertion into control panels. The relay supports a wide adjustable current range from 0.1 A to 30 A, so it works with small and medium motors. It accepts supply voltages from 24 V DC up to 240 V AC/DC, making it flexible for various control systems. The module offers both manual and automatic reset modes, giving engineers options for restart strategies after a trip. Its IP20 front‑panel rating guards against accidental contact, while the rear terminals remain easy to access.
🔌 The EMR‑3MP0‑2A0BB features multiple LED indicators for power, trip status, and fault type. These indicators help technicians diagnose issues quickly without extra test tools. The AmpGard adaptor ensures secure terminals and consistent torque on all connections. The relay’s trip class is 10 A, and it withstands starting currents up to six times its setting without nuisance tripping. It fits standard DIN‑rail or panel‑mount installations, and its compact size (90 × 35 × 69 mm) saves space in crowded control cabinets. Operating temperature ranges from –25 °C to +60 °C, which covers most factory environments. Certifications include UL, CSA, and CE, ensuring compliance with international safety standards. The housing is made of flame‑retardant thermoplastic, and all internal circuits have conformal coating for resistance to dust, moisture, and vibration.
🛡️ In recent industrial news, motor protection has become more critical as factories push for higher uptime and energy efficiency. Predictive maintenance solutions now integrate smart relays like the EMR‑3MP0‑2A0BB with networked monitoring systems. These systems collect trip data and runtime statistics to forecast potential motor failures before they occur. Many manufacturers are upgrading legacy overload relays to electronic versions that offer programmable features and remote diagnostics. Eaton’s range of AmpGard adaptors boosts service speed by letting teams swap relays without rewiring. Reports from heavy‑industry users show that adopting electronic motor protection can reduce unplanned downtime by up to 40 %. As factories move toward Industry 4.0, relays with flexible communication options and easy panel integration are in high demand.
