FAQs
The ER54016UW is designed for industrial control panels requiring safe isolation with a four-pole design and a 600 V rating. It fits standard panel spaces and its compact dimensions (10.4 in depth, 6.7 in height, 7.2 in width) simplify mounting alongside other motor control components. Its stainless steel NEMA 4X enclosure is ideal for washdown environments, reducing enclosure-related clearance concerns during retrofit or OEM installations.
ER54016UW provides a 16 A amperage rating and HP compatibility of 3, 5, and 10 hp at 208, 240, 480, and 600 V. This enables versatile motor control across multiple line voltages, allowing a single disconnect device to support diverse equipment such as conveyors, pumps, and fans within the same installation or across a family of machines.
Yes. The unit is CSA Certified and UL Listed, confirming regulatory compliance and supplier reliability. Its NEMA 4X enclosure and stainless steel construction further reinforce suitability for harsh environments, helping to meet industry safety and quality requirements in sectors like manufacturing, packaging, and process industries.
By providing definitive, lockable isolation with a robust NEMA 4X enclosure, the ER54016UW reduces arc flash exposure and protects against dust, moisture, and corrosion. The four-pole design simplifies wiring and maintenance, while its warranty provisions align with Eaton's service policy, offering one year from installation or eighteen months from shipment to support lifecycle planning.
Considerations include ensuring the panel space accommodates the 10.4 in length, 6.7 in height, and 7.2 in width, and that your motor load aligns with the 16 A / up to 10 hp ratings at the intended voltages. The four-pole, R-Series device integrates with standard motor control components and fits within washdown environments due to its 4X enclosure and stainless steel construction.
