CI Contactors and Motor Starters Type CI 110 - 141 - DANFOSS INDUSTRIAL AUTOMATION

CI Contactors and Motor Starters Type CI 110-141 from Danfoss Industrial Automation are electromechanical switching devices designed for controlling motors, resistive loads, and other inductive circuits in industrial environments. These contactors feature a compact modular design with ratings typically ranging from 9A to 65A AC-3 utilization category, supporting voltages up to 690V AC. They incorporate double-break main contacts with silver alloy tips for reliable arc extinction, and are available in 3-pole (3P) configurations. The CI series includes integrated auxiliary contact blocks (1NO+1NC standard) and coil options for AC and DC control voltages (e.g., 24V, 110V, 230V, 400V). Mechanical endurance exceeds 10 million operations, with electrical endurance up to 1 million cycles at rated current. These devices are also known globally as motor contactors, magnetic starters, or power relays, and comply with IEC 60947-4-1 and UL 508 standards.

CI contactors and motor starters are primarily used in motor control centers (MCCs), distribution panels, and automation cabinets for starting and stopping three-phase induction motors in pumps, fans, conveyors, and compressors. They are also deployed in HVAC systems, water treatment plants, and material handling equipment. The integrated thermal overload relays (e.g., Type CI 110-141 with adjustable current settings) provide motor protection against overload and phase failure. Applications include direct-on-line (DOL) starting, star-delta starting, and reversing motor control circuits in industrial automation networks.

The CI 110-141 category includes subcategories such as CI 110 contactors (e.g., CI 110-9, CI 110-12, CI 110-18) with rated operational currents from 9A to 18A, and CI 141 contactors (e.g., CI 141-22, CI 141-32, CI 141-40) covering 22A to 40A. Motor starters combine contactors with thermal overload relays like the CI 110-141 series. The article code structure typically follows the pattern "CI [series]-[current rating]", e.g., CI 110-9 for a 9A contactor. Accessories include auxiliary contact blocks (CI 110-141-AUX), coil assemblies, and mechanical interlock kits for reversing applications.
