PowerFit single-pole connectors are built for demanding power distribution and intermate with major single-pole brands. Available in 400A and 660A , each inline and panel-mount model integrates a patented key-release pin for safe, tool-free uncoupling and reduced accidental disconnects. Housings use high-impact, heat-resistant, flame-retardant thermoplastic; line connectors add an ergonomic rubber grip for confident handling. An M40 cable gland is standard, and once mated the assembly achieves IP67 ingress protection. A large, positive push-button mechanism speeds coupling/uncoupling, while color-keyed bodies and clear phase/line markings simplify on-site identification. Sliver-plated brass contacts deliver low resistance and excellent conductivity, and the insulating cotter pin is engineered from POM for high stiffness, low friction, and minimal moisture absorption.
