Selling Policy 25-000 - Distribution and Control Products and Services
Three-pole JG frame with 150 A rating and line/load terminals enables precise, dependable overcurrent protection. The business impact is improved protection density and simplified panel design, reducing space requirements and installation time. This is especially applicable to industrial control panels and motor feeders in manufacturing environments. Fixed thermal and adjustable magnetic trip (T185) delivers stable protection while enabling selective coordination with downstream devices. The business impact is minimised nuisance trips and enhanced safety compliance across variable loads, making it ideal for pumps, conveyors, and fans in process industries. Interrupt ratings across voltages provide resilience against short circuits, reducing risk of arc flash and equipment damage and enabling safe, fast disconnections. This is critical in distribution panels and machine rooms within harsh industrial settings. Metric mounting hardware and a compact footprint ease installation and retrofit in existing panels, saving installation time and labor costs. The Eaton compatibility ecosystem supports quick accessory integration, improving serviceability in constrained spaces common to control panels and switchgear. Compliance and warranty support procurement confidence and long-term reliability, with UL Listed, CSA Certified, IEC Rated, and CE Marked status plus a one-year warranty (or 18 months from shipment). This combination reduces regulatory risk and supports global project execution and maintenance planning.
