FAQs

The L1120PW uses a back-wiring method suitable for #18-10 AWG conductors and accommodates 3 wires in a 250V, 20A system. This design enables straightforward field terminations, reducing crimping steps and speeding panel assembly while maintaining a secure, code-compliant connection for industrial equipment.
IP67 protection means immersion resistance up to 1 meter for 30 minutes and dust exclusion. In practice, this reduces field failures in outdoor enclosures, damp workshops, and maritime settings, supporting compliant installations and minimizing moisture-related corrosion and electrical faults.
Yes. The L1120PW supports NEMA L11-20, three-pole, three-wire configurations, 250 V, and 20 A, with a watertight Santoprene body. It is well suited for motors, pumps, conveyors, and other equipment exposed to weather, washdowns, and temperature cycling, delivering reliable power connections.
This plug is RoHS compliant and features IP67 ingress protection. It aligns with standard NEMA L11-20 configurations for rugged industrial hardware, supporting customer compliance programs and procurement standards while ensuring safe, durable operation in harsh environments.
The locking mechanism reduces accidental disconnection in vibration-prone equipment, and the steel contacts with a Santoprene housing resist wear and chemical exposure. These design choices translate to longer service life, fewer replacement parts, and lower maintenance costs across motors, conveyors, pumps, and automated lines.
