This Hubbell Twist-Lock® female connector provides a secure locking connection for 50 A, 250 V three-phase delta industrial power applications. Its tough nylon housing resists impact, while the heavy-duty two-piece cord clamp provides strain relief for demanding job-site connections. Oversized brass contacts help minimise operating temperature, and box terminals allow high clamping pressure without damaging conductor strands.
