FAQs
Yes. This three-pole breaker is designed for standard distribution enclosures with a 1-1/4" trade size. It features a threaded enclosure cover for secure mounting and compatible fittings, allowing straightforward replacement in existing hazardous-location panels while maintaining system integrity.
Expect 30 A amperage rating, 600 Vac voltage rating, thermal-magnetic trip, and a three-pole configuration. The FDB frame type, copper-free aluminum enclosure, and non-interchangeable trip provide reliable, fixed trip characteristics suitable for coordinated protection in demanding environments.
Yes. It is certified for Hazardous/Classified Locations with NEC/CEC compliance and NEC hazardous ratings Class I Division 1 and 2, Class II Division 1 and 2, and Class III, along with NEMA ratings 3/4/7/9, making it suitable for explosive atmospheres and harsh environments.
The unit adheres to NEC/CEC standards and is certified for hazardous locations (Class I, II, III). UL certification references are available for the explosionproof construction, with documentation linked in Eaton’s installation and datasheet resources, ensuring regulatory due diligence is met.
Threaded cover simplifies enclosure sealing during maintenance, copper-free aluminum reduces corrosion and weight, and the non-interchangeable trip prevents accidental misconfiguration. Combined with dedicated installation instructions (IF 1016) and a robust enclosure, this minimizes downtime and supports long-term reliability in harsh industrial settings.
