Product Description
The MMTC 2EBX is a NEMA 7 and NEMA 9 rated explosion-proof two-button (OPEN-CLOSE) surface-mount control station engineered for Class I and Class II hazardous locations. The cast metal enclosure contains any internal ignition and prevents hazardous atmospheres from reaching internal electrical components. Two vertically-arranged momentary normally-open push buttons - OPEN and CLOSE - are each rated at 6A @ 125VAC for reliable gate and door control in petrochemical facilities, grain elevators, paint booths, and similar severe environments. Sharing the same housing dimensions as the single-button 1EBX (H: 6-1/8" x W: 3" x D: 4-3/8"), the 2EBX provides dedicated bidirectional command capability in a surface-mount hazardous-location package.

Frequently Asked Questions
Q: What hazardous location classifications does the 2EBX satisfy?
A: The MMTC 2EBX is rated NEMA 7 and NEMA 9, making it suitable for Class I (Groups C & D) hazardous locations involving flammable gases or vapors, and Class II (Groups E, F, G) hazardous locations involving combustible dusts. It is engineered specifically for environments where standard control stations would pose an ignition risk.
Q: How many buttons does the 2EBX have and what are their electrical ratings?
A: The 2EBX features two vertically-mounted momentary normally-open push buttons labeled OPEN and CLOSE. Each button is rated at 6 amps at 125VAC, providing reliable momentary contact output for controlling gate operators or door control systems in hazardous environments.
Q: What material is the 2EBX enclosure made from and why does it matter?
A: The 2EBX enclosure is constructed of cast metal, which is a fundamental requirement for NEMA 7 and NEMA 9 explosion-proof ratings. The robust cast metal body contains any internal ignition and prevents external hazardous atmospheres from reaching internal electrical components, ensuring safe operation in explosive environments.
Q: How is the 2EBX mounted and what does surface-mount mean for installation?
A: The 2EBX is a surface-mount control station, meaning it mounts directly onto a wall, post, or conduit system without requiring a recessed or in-wall installation. Surface mounting simplifies installation in industrial and hazardous environments where conduit runs are typically exposed.
Q: How does the 2EBX differ from the MMTC 1EBX control station?
A: The 2EBX shares the same form factor and dimensions (H: 6-1/8" x W: 3" x D: 4-3/8") as the MMTC 1EBX single-button explosion-proof control station. The key difference is that the 2EBX provides two buttons (OPEN and CLOSE) for dual-command control, whereas the 1EBX provides a single-button operation, making the 2EBX ideal for applications requiring discrete open and close commands.
