FAQs
Ensure the replacement matches the 1-1/4" trade size, 3-pole configuration, and 240 V AC rating. Verify the enclosure is compatible with copper-free aluminum construction, and confirm the threaded cover seals against dust and moisture. Check that the trip characteristics remain non-interchangeable to preserve protective intent and regulatory compliance.
This device carries NEC/CEC standards, Hazardous/Classified Locations area classifications, and NEMA ratings 3, 4, 7, and 9. These certifications confirm suitability for hazardous environments, ensure regulatory compliance, and support safe operation in chemical, mining, and offshore applications, reducing risk and facilitating audits.
The thermal element provides overload protection by heat-sensing, while the magnetic element handles short-circuit surges. Together they offer fast response to excessive current while minimizing nuisance trips, protecting motors and drives in demanding loads typical of hazardous-location installations.
Yes. The enclosure is copper-free aluminum for corrosion resistance and lighter weight, and the threaded cover design enhances sealing. This combination improves durability in harsh environments and simplifies field maintenance without compromising accessibility or safety.
Benefits include reduced downtime from reliable protection, lower maintenance due to corrosion-resistant copper-free aluminum, and improved compliance with NEC/CEC and NEMA ratings. The non-interchangeable trip minimizes misconfiguration, helping avoid costly replacement errors and ensuring consistent protection across the installation.
