Power management company Eaton’s Crouse-Hinds developed the first explosionproof enclosure with clamping technology to help oil and gas and other industrial customers enhance safety and dramatically improve productivity.
The challenges – Installation Errors and Time
Traditional classified enclosures require a significant number of bolts designed into their covers.
When properly installed, a traditional NEMA 7 enclosure is extremely safe. However, human installation error may result in bolts being left out or not torqued properly. If internal combustion were to occur inside an incorrectly installed enclosure, a flame could escape and ignite the outside atmosphere.
Additionally, opening and closing traditional bolted enclosures is a labor-intensive task. Facilities that regularly inspect their enclosures as part of a preventative maintenance plan can spend thousands of dollars a year on labor.
The solution – The clamped EBMX enclosure from Eaton’s Crouse-Hinds Division.
This Eaton product is the first NEMA 7 classified enclosure to use clamping technology. The clamps on the EBMX automatically apply even pressure across the flame path for an error-proof installation. There is no need to worry about missing or improperly torqued bolts creating an explosion hazard in your facility.
The EBMX also offers a significant reduction in installation and maintenance costs due to its revolutionary design that makes opening and closing the EBMX significantly faster than traditional enclosures.
The EBMX enclosure from Eaton’s Crouse-Hinds Division is rated Class I, Divisions 1 and 2, and has a NEMA 4X rating to protect against water ingress. The EBMX is designed for motor control devices, including starters, combination-starters, disconnect switches and circuit breakers. Eaton’s enclosure is rated for 65,000 ampere interrupting capacity (KAIC) at 480 volts and meets Underwriters Laboratories® (UL) 1203 standard for explosion-proof and dustproof equipment for use in hazardous locations. The equipment also meets National Electrical Code® (NEC) and Canadian Electrical Code (CEC) requirements and are built to withstand extreme temperatures.
