APM Circuit Breaker Boots – A Small Shield, a Huge Difference
APM Hexseal’s circuit breaker boots provide rugged, intelligent sealing for toggle-style breakers, with options for front-panel or back-panel mounting—each tailored to specific engineering needs.
Front-mounted boots are ideal for quick retrofits and easy access on existing panels, while back-mounted boots integrate cleanly into the panel for a flush, secure seal.
Made in the USA from patented RUBRGLAS™ silicone, all models offer IP68 protection against water, oil, dust, and vibration—perfect for military, marine, and industrial environments.
