CONTROL AND CONTACTORS
Contactors and control relays are electromechanical switching devices designed for remote control of electrical loads in industrial and commercial power systems. These components are rated for continuous duty and feature coil voltages from 24V AC/DC up to 690V AC, with contact configurations including 3P, 4P, and auxiliary contact blocks. The main contacts are typically rated for AC-3 and AC-4 utilization categories, handling currents from 9A to 630A. Control relays offer multiple NO/NC contact arrangements for logic and interlocking functions. All devices comply with IEC 60947-4-1 standards and are available with screw, spring, or ring tongue terminals for secure wiring.
These components are fundamental in motor control centers (MCCs), distribution panels, and automation cabinets for starting, stopping, and protecting three-phase motors, resistive loads, and lighting circuits. They are deployed in HVAC systems, conveyor belts, pumps, compressors, and machine tools across manufacturing plants, water treatment facilities, and building management systems. Contactors also serve in power factor correction banks and emergency lighting transfer schemes.
Our inventory includes general-purpose contactors (SI02-09 to SI02-630), reversing contactors with mechanical interlocks, and control relays (SI02-RL series) with 2 to 8 poles. The main article codes follow the pattern SI02-XX-YY, where XX indicates rated current (e.g., 09 for 9A, 32 for 32A) and YY denotes coil voltage (e.g., 24 for 24V, 230 for 230V). We stock both AC and DC coil versions, with optional add-on modules like surge suppressors and timer blocks.
We offer express worldwide shipping with real-time pricing and stock visibility. Our team of electrical engineers provides personalized technical support for contactor selection, coil voltage matching, and auxiliary contact integration. Each product includes detailed datasheets with thermal dissipation curves and mechanical endurance ratings.
