8502SDO2V02 - Square D Magnetic Contactor

8502SDO2V02 - Square D Magnetic Contactor

Upgrade your motor control systems with the Square D 8502SDO2V02S Magnetic Contactor, a high-performance, NEMA Size 2, three-phase solution engineered for long-lasting, reliable service in demanding industrial environments. Designed for full-voltage switching of motors, transformers, heating loads, and capacitors, this contactor handles up to 45 amps continuously at 600 VAC. With its 120 VAC coil, you get precise, independent control – perfect for building smarter, safer systems. Rugged screw‑clamp terminals and open-style housing make panel installation and maintenance a breeze, while a 100 kA SCCR (when combined with the right breakers) ensures peak resilience under high-fault conditions. Ideal for commercial motor control centers and HVAC setups, it's UL-listed and CSA-qualified for worldwide safety standards.
