Eaton Crouse-Hinds EMP0592 Selector Switch - Hazardous Area
Part Number: EMP0592
Quick Summary
The Eaton Crouse-Hinds EMP0592 selector switch operator provides reliable control for hazardous-area machinery. In harsh industrial settings, operators must resist explosive atmospheres, ingress, wear, and tampering to prevent costly downtime and safety incidents. It carries NEC/CEC certifications with hazardous ratings for Class I Division 1 and 2, Class II Division 1 and 2, and Class III, plus NEMA ratings for enclosures 3, 7, and 9. The standard assembly, two contact blocks, and left-only key removal simplify wiring, panel layout, and field safety checks in retrofit and new-build projects. For manufacturers and maintenance teams prioritizing uptime and compliance, EMP0592 delivers a robust, scalable solution compatible with two normally open and two normally closed circuits.

FAQs
To install EMP0592, verify panel compatibility with the two-contact block arrangement, mount in standard footprint, and wire two normally open and two normally closed contacts per the control logic. Ensure the device is secured in a suitable hazardous-area enclosure and that the key-operated switch remains accessible for safe operation.
EMP0592 carries NEC/CEC compliance for hazardous locations with Class I Division 1 and 2, Class II Division 1 and 2, and Class III ratings, and is offered in NEMA enclosures 3, 7, and 9. These specs support safe operation in oil, gas, chemical processing, and other demanding environments.
Yes. EMP0592 provides two normally open and two normally closed contacts across two contact blocks. This arrangement supports flexible control logic for start/stop sequences, interlocks, and signaling in hazardous-location panels.
Ideal for hazardous-location motor control, process-line panels, and equipment enclosures in oil & gas, chemical processing, maritime, and mining sectors. The two-position, key-operated selector supports secure operation, while the standard assembly simplifies retrofits and new installations in restricted zones.
The EMP0592 offers tamper resistance via left-only key removal, durable construction for volatile atmospheres, and straightforward installation that reduces commissioning time. Its NEC/CEC and NEMA compliance lowers regulatory risk, minimizes unplanned downtime, and streamlines maintenance planning for regulated facilities.
