FAQs
Yes. The ER53080UW is a three-pole, 600 V rated enclosed rotary disconnect designed for motor circuits up to 40 hp across multiple voltages. It fits typical panel layouts and simplifies wiring by consolidating isolation into a single, non-fusible switch.
The 80A rating provides ample headroom for motor starting currents and load transients common in conveyors. As a non-fusible, enclosed rotary switch, it offers predictable energization and de-energization, reducing wear on contact surfaces and improving uptime during routine maintenance.
The NEMA 4X stainless enclosure is ideal for washdown areas, outdoor installations, and corrosive environments such as chemical processing or food and beverage processing. Its corrosion resistance helps extend service life and lowers maintenance frequency in tough settings.
The unit is CSA Certified and UL Listed, confirming adherence to electrical safety and performance standards. These certifications streamline approvals in regulated facilities and support competitive procurement by meeting common compliance requirements.
By combining robust corrosion resistance, straightforward non-fusible isolation, and a compact footprint, the ER53080UW reduces maintenance intervals and spare-parts inventory while lowering downtime during motor servicing and panel upgrades, delivering tangible total cost of ownership benefits for mid-range industrial applications.
