Watertight construction provides IP66 and NEMA 4/4X protection, guarding against moisture, dust, and washdown exposure to extend service life in harsh environments. This reduces corrosion risk and unplanned downtime in outdoor enclosures and wet factory floors, delivering measurable reliability improvements. The four-pole, four-wire locking configuration ensures a secure connection that resists vibration and inadvertent disconnections, minimizing interruptions during motor starts and peak loads. Construction uses thermoplastic, glass-filled nylon for the body and nickel-plated bronze for contacts, delivering high impact strength and corrosion resistance in temperature cycling and chemical exposure typical of industrial settings. Back wiring supports #14-8 AWG and simplifies field terminations, while torque ratings of 14-16 lbf-in for #10-14 AWG and 20 lbf-in for #8 AWG ensure consistent, safe mating without over-torquing. The device’s rugged industrial specification grade and cULus listing streamline compliance, procurement, and long-term maintenance planning, delivering lower lifecycle costs for OEMs and integrators. In short, 30A capability at 120/208V supports common motor control and distribution needs with reduced rework and faster service.

FAQs
Plan back-wiring steps by confirming conductor size within #14-8 AWG and preparing conductors for insertion. Apply the specified torque: 14-16 lbf-in for #10-14 AWG, and 20 lbf-in for #8 AWG. Ensure the four-pole, non-grounding configuration matches your circuit and verify a proper seal to maintain IP66/NEMA protection after termination.
The 30A rating accommodates moderate motor and control loads on 120/208V three-phase systems, supporting reliable power delivery for common industrial equipment. The four-pole, four-wire non-grounding design ensures correct conductor termination and robust performance under load, reducing voltage drop and improving startup consistency in demanding environments.
Yes. The receptacle features IP66 protection and NEMA ratings including 4/4X and 3R, delivering moisture, dust, and washdown spray resistance. Its thermoplastic, glass-filled nylon body and nickel-plated bronze contacts withstand chemical exposure and vibration, making it appropriate for outdoor enclosures, food processing areas, and harsh manufacturing floors.
The 3433RWBK is cULus Listed, with environmental protections such as IP66 and NEMA ratings (4/4X/12, 3R). These certifications validate safety and environmental performance, simplifying approvals for North American facilities and supporting procurement standards for regulated industries like food processing and pharma.
Locking connections reduce downtime from unplugging during high-demand cycles, while durable materials resist wear and corrosion in challenging environments. Back wiring speeds field terminations, lowering installation labor. Together, these factors translate to improved equipment uptime, lower maintenance costs, and a favorable return-on-investment for production lines.
