Overview
The Pass & Seymour L1430-C is an industrial-grade polarized locking connector designed for robust power distribution in demanding environments. With NEMA L14-30R configuration, this connector delivers 30 amperes at 125/250 volts across 3 poles and 4 wires. Built by Legrand’s Pass & Seymour division, the L1430-C features brass alloy plug blades and tin-plated stainless steel contacts that resist heat rise and corrosion, making it ideal for manufacturing facilities, job sites, and mobile power applications.
Key Features
- Industrial-strength brass alloy blades — resist heat rise and provide superior conductivity for reliable long-term operation
- Polarized locking design — Turnlok twist-lock mechanism ensures secure, vibration-proof connections that cannot accidentally disconnect
- Nylon 6/6 body — impact- and corrosion-resistant shell material with black back and white front for clear visibility
- Raised ribbed gripping profile — enables non-slip turning for positive lock and unlock; scallop shell design aids insertion and withdrawal
- Double dovetail cord protection — prevents cord pull-out and separation under load or vibration
- Integral flexible rubber grommet — seals around SO cord to protect wiring chamber from oils, water, and shop debris
