Euro-Style Quick-Connect Blocks

Korner OK501 Series European‑Style Quick-Connect Terminal Blocks

The Korner OK501 Series, now available through Curtis Industries, is a family of heavy-duty quick-connect terminal blocks designed to provide reliable power distribution and wire termination in demanding electrical applications. Featuring industry-standard 0.250″ (6.35 mm) Quick-Connect terminals and an 11 mm pitch, the OK501 series offers a robust alternative to traditional European and North American quick-connect terminal strips.

Engineered for appliance, lighting, HVAC, industrial control, and power distribution applications, the OK501 series combines durable thermoplastic insulation with Ni-plated brass terminals to deliver dependable electrical performance, simplified assembly, and long service life.

The OK501 series is particularly well suited for OEMs seeking alternatives to legacy quick-connect terminal strips, including the WECO 307-PC, 307-PCM, and 3070-PCM series. Similar terminal spacing, termination style, and electrical performance make the OK501 an excellent choice for new designs, product refreshes, and long-term sourcing strategies.
