FAQs
ER53030UPGB is designed for standard panel mounting in three-pole configurations and fits typical control enclosures measuring about 7 by 5 by 5.5 inches. When planning installation, confirm available mounting space and terminal access, and verify that the enclosure rating matches your environment. Compliance with NEC/UL wiring guidelines ensures safe integration into existing motor circuits.
Rated for 30 amperes and 600 volts, the ER53030UPGB supports motor loads up to 20 hp at 600V, 15 hp at 480V, and 7.5 hp at 208/240V, with a three-pole configuration. This rating provides a robust buffer for startup currents and short-time overloads. Always pair the switch with properly sized fuses or breakers and correct wiring gauges.
Yes. The ER53030UPGB uses a polycarbonate non-metallic enclosure rated NEMA 4X, designed for washdown and damp environments. This protects internal components from water, dust, and chemicals, supporting longer service intervals and reducing unnecessary downtime in harsh facilities. For outdoor exposure, ensure appropriate weather considerations and mounting clearances.
The switch is CSA Certified and UL Listed, confirming compliance with recognized safety standards for electrical equipment. These certifications ease regulatory approvals in industrial facilities and support warranty eligibility. They provide confidence in health, safety, and performance for motor-disconnect applications and broader equipment integration.
Maintenance is typically minimal due to a rugged enclosure and simple mechanical design, reducing lubrication needs and field adjustments. The protective NEMA 4X housing lowers external damage risk, helping prevent unplanned downtime. Over the asset lifecycle, improved uptime, faster serviceability, and safer isolation translate to lower operating costs and a faster return on investment.
