Eaton 25W49 Watertight locking connector - cULus Listed
Part Number: 25W49
Quick Summary
Eaton Arrow Hart watertight locking connector is a rugged, secure power connection for industrial equipment and outdoor installations. It delivers reliable 15A at 250V in harsh environments, protecting against moisture and dust. For engineers and procurement teams, moisture ingress and field wiring complexity are common pain points; this connector mitigates both with a robust IP67/NEMA-rated design and back-wiring capability. Built to endure washdowns and vibration, it combines nickel-plated brass contacts with Santoprene elastomer in a yellow housing for high visibility. The result is safer, faster installations and fewer re-entries for maintenance, translating to reduced downtime and improved system availability.
