Reliable Protection for Every Installation

With clear visual indicators and secure fuse retention, you can quickly verify circuit status and replace blown fuses without guesswork. The robust housing resists dust, moisture, and mechanical stress, making these switches ideal for demanding environments.

Easy to Install and Maintain

Installers appreciate tools that save time and reduce errors. The KETO series features a modular design that snaps neatly into standard panel layouts. Terminal connections are clearly marked and easy to access, even in tight spaces. The ergonomic operating handles allow smooth switching, and the fuse replacement process is straightforward, cutting down maintenance downtime.

Wide Range of Current Ratings and Configurations

No two projects are the same, and the KETO series covers the most common requirements. Available in 160A, 250A, 400A, and 630A ratings, you can match the exact load for your circuit. Choose from single-pole or three-pole versions, with or without integrated handles, and select from various mounting and accessory options. This flexibility means fewer special orders and faster project completion.

Built for Safety and Long-Term Performance

Safety is non-negotiable in electrical work. The KETO disconnect switches are engineered with insulated barriers, arc-resistant components, and secure locking mechanisms to protect both personnel and equipment. The high-quality materials ensure stable performance over years of operation, even under frequent switching or heavy loads. Trust the Jean Mueller KETO series to keep your installations safe, compliant, and running smoothly.
