Lockout Tagout (LOTO) devices like this clamp-on breaker lockout are essential for safe, compliant maintenance in industrial, commercial and institutional settings. Whether you’re working on 120-277V single-pole breakers or large 480-600V disconnects, this universal breaker lockout fits securely, prevents accidental energization and supports multiple padlocks for group lockout.
Made from rugged, non-conductive materials, this device installs easily without tools thanks to its thumb-screw clamp design. Once installed, a padlock is applied and only the authorized technician can remove it—ensuring equipment remains de-energized until the work is complete.
