Crouse-Hinds series Class I, Division 2 STE main breakers utilize an encapsulated breaker in a Type 4X stainless steel enclosure for easy access, increased safety and decreased maintenance costs. The factory sealed STE main breaker provides overcurrent and short circuit protection for low voltage power, lighting and heat tracing applications in hazardous locations, such as refineries, chemical and petrochemical plants, mining, food processing, corrosive and industrial processing facilities.
The STE breaker is fully encapsulated so that sparking or heat are not capable of igniting an explosive atmosphere. This allows for the use of lightweight enclosures for easy installation. STE breakers also open in seconds via two quarter-turn screws, versus up to 30+ bolts as with traditional NEMA 7 enclosures.
