UG412RMW250 - 125A, 120/240V, Disconnect Switch

The UG412RMW250 is a rugged, industrial-grade Disconnect Switch engineered for safe electrical isolation in demanding environments. Built to support proper lockout/tagout procedures and to perform clean disconnections under load, this device delivers consistent reliability when it matters most—during maintenance, testing, or servicing of energized equipment.

Key strengths that set the UG412RMW250 apart:

• 125A current rating with a 120/240V supply capability, making it a true workhorse for medium-to-large industrial loads.
• NEMA 3R enclosure designed for outdoor and harsh environments, providing dependable protection against rain, dust, and seasonal weather while keeping the isolation path secure.
• Lockout/Tagout compatibility to support compliant maintenance practices, reducing risk by ensuring energy sources remain isolated during service.
• Safe under-load disconnection capability ensures reliable isolation even when circuits are energized, helping minimize downtime and surge-related issues.
• Long-term durability built for continuous operation in commercial and industrial settings, delivering steady performance over years of use.

What problems does it solve?

When maintenance or repair must happen on energized equipment, the UG412RMW250 provides a trustworthy, code-conscious isolation point. Its robust construction and weather-rated enclosure help prevent inadvertent energization, while the LOTO-friendly design simplifies safe downtime procedures. For facilities that rely on dependable service disconnects, this switch helps minimize downtime and maximize worker safety.

Ideal use cases

• Service disconnects for motors, pumps, and conveyors in factories and warehouses
• Maintenance shutoffs for outdoor electrical equipment, electrical rooms, and exterior controls
• Safety isolations during equipment upgrades, inspections, or routine testing

Why choose this over generic alternatives?

The UG412RMW250 is purpose-built for reliability in real-world conditions. Its 125A rating pairs with a weather-resistant NEMA 3R enclosure to deliver a dedicated isolation point that stays secure in rain, dust, and temperature swings. Unlike generic switches, this model emphasizes under-load disconnection safety, LO/TO readiness, and durable construction suited to continuous industrial service.

Practical tips for deployment

• Plan the installation in a weather-protected location whenever possible, then rely on the NEMA 3R enclosure for outdoor or semi-exposed sites.
• Coordinate with your lockout/tagout program to designate the UG412RMW250 as the official isolation point during maintenance.
• Ensure wiring gauges and terminations match the 125A rating and the 120/240V supply to maintain safe, reliable operation.
• Incorporate routine inspections of the enclosure seals and mechanical integrity to preserve long-term performance.

For facilities seeking a dependable, purpose-built disconnect switch that aligns with industrial safety standards and practical maintenance workflows, the UG412RMW250 delivers¹ verified isolation, durable construction, and straightforward integration into existing electrical systems.

Note: Always follow local electrical codes and manufacturer guidelines when installing and operating disconnect switches.
