The GE ABB TH3363 is a robust, fusible safety switch from the Spec-Setter series, built for commercial and industrial environments that demand reliability, safety, and consistent performance. When installed in compliance with the National Electric Code, this switch is suitable for use as service entrance equipment. Designed for versatility, the TH3363 supports multiple fuse types, including Class H, K, J, and R, making it adaptable to various application needs. It also features a visible blade design for easy inspection and a direct-drive, quick-make, quick-break mechanism, ensuring a clear and reliable ON/OFF operation.
Features
-
Quick-Make, Quick-Break Mechanism: The handle mechanism provides a direct-drive action that quickly "snaps" the contacts open and closed, reducing arcing and contact wear, and providing positive ON/OFF indication.
-
Safety Interlocks: Features a full cover interlock and a coin-proof, defeatable interlock. This prevents the cover from being opened when the switch is in the ON position, ensuring safety during operation.
-
Visible Blades: The internal blades are clearly visible, allowing maintenance personnel to visually confirm the switch is open and isolated before beginning work.
-
Lockout/Tagout (LOTO) Ready: The "donut" handle accepts up to three padlocks in the OFF position, meeting critical LOTO safety requirements.
-
High Short Circuit Rating: The 200kA interrupting capacity (with Class R or J fuses) makes it suitable for locations with high available fault currents.
- Horsepower Ratings: 30 hp with standard fuses | 75 hp with time-delay fuses
