Feature is watertight locking design with IP67/NEMA 6 protection, offering superior moisture resilience which translates to fewer equipment failures and lower maintenance costs in outdoor or washdown areas. This directly impacts uptime and plant throughput in manufacturing lines, where uninterrupted power is critical. Application spans industrial facilities, food and beverage processing, and outdoor equipment where rugged sealing is mandatory. Feature indicates back wiring capability for #18-10 AWG, enabling faster terminations and reduced on-site labor, improving installation efficiency and commissioning speed. Business impact is measurable through reduced wiring time and lower field rework, with applications in control panels and junction boxes across process industries. Feature includes 125 V, 15 A rating with L5-15 configuration, delivering reliable power delivery for small to mid-size equipment packages. This supports tighter electrical routing and safer cord management in crowded panels. Feature highlights nickel-plated brass contacts and Santoprene elastomeric seals, which enhance conductivity and resistance to oils and detergents, reducing contact resistance and extending component life in harsh environments. Application benefits include longer service intervals and predictable performance in high-dust or washdown zones, a common concern in plant floor automation. Feature notes a nylon body and a rugged, extra heavy-duty industrial specification grade design, which delivers impact resistance and long-term durability in demanding installations. In practice, technicians gain a dependable, fill-ready solution that scales with panel complexity and retrofit projects, allowing quick upgrades without extensive rewiring. Cord diameter support of 0.3-0.65 in and back wiring align with common field wiring practices, minimizing compatibility issues during upgrade programs. The connector’s two-pole, three-wire grounding arrangement provides secure grounding paths, ensuring safer operation under vibration and repeated mating cycles in automated lines.

FAQs
To install the 25W47BK with back-wiring, first ensure power is disconnected. Prepare conductors #18-10 AWG, insert them into the back-wiring terminals, and tighten to the manufacturer’s torque specification of 14 lbf-in. Verify insulation clearance and secure the housing to prevent moisture ingress. This approach minimizes field termination errors and speeds up panel assembly.
The 25W47BK is rated for 15 A at 125 V with an L5-15 configuration. It features two poles and three wires with grounding. Its environmental protections include IP67 and NEMA ratings 6, 6P, 4, and 4X, ensuring reliable operation in washdown, dusty, and outdoor environments.
Yes. With IP67 and NEMA 6/6P/4/4X ratings, the 25W47BK is designed to withstand moisture, dust, oil, and washdown procedures. The Santoprene elastomeric seal and nylon housing provide durable resistance, making it a dependable choice for manufacturing floors, packaging lines, and outdoor equipment.
The 25W47BK is cULus Listed, indicating compliance with recognized safety standards. This certification supports reliability in North American installations and simplifies compliance during audits. Combined with its IP67/NEMA protections, it assures distributors and technicians of robust, code-compliant performance in demanding applications.
The ROI comes from reduced downtime due to fewer moisture-related failures, longer connector life from corrosion resistance, and faster field terminations reducing labor costs. In process and manufacturing environments, this translates to more consistent production cycles, lower maintenance intervals, and safer, more reliable power connections across critical equipment.
