325UL - 25A, 600V, 3-Pole, Disconnect Switch, NEMA 4X

Meet the 325UL 25A, 600V, 3-Pole Disconnect Switch with a NEMA 4X enclosure — a rugged, reliable solution built to deliver clean on/off isolation and dependable overcurrent protection in the harshest industrial and commercial environments. Designed for straightforward maintenance and fast service, this switch keeps critical equipment isolated when you need it and protected when you don’t.

• Model: 325UL
• Amperage: 25A
• Voltage: 600V
• Poles: 3-Pole
• NEMA Rating: 4X

What makes the 325UL stand out

Three-pole design ensures complete isolation across all conductors, so motors and three-phase equipment can be safely shut down and serviced. The NEMA 4X-rated enclosure provides robust protection against rain, dust, and corrosion, making this switch suitable for outdoor installations, washdown environments, and cramped or exposed enclosures without compromising safety. Its compact footprint fits neatly into control panels and disconnect enclosures, delivering reliable performance without hogging space.

Ideal applications

• Motor disconnects for conveyors, pumps, fans, and compressors
• Panelboard isolation points to simplify maintenance and sectional power shutdowns
• Branch circuit protection in demanding industrial or commercial setups
• Outdoor equipment or environments where weather and corrosion resistance are essential

Why this matters in real-world use

Choosing a dedicated disconnect switch with a 3-pole configuration reduces the risk of locked-rotor damage and unintended energization during service. The 600V rating supports a broad range of systems, while the 25A capacity provides a precise balance between protection and performance for mid-size motors and control circuits. The durable NEMA 4X enclosure means maintenance teams can access wiring and terminals with confidence, knowing the device will stand up to moisture, dust, and corrosive exposure.

Practical guidance and best practices

• Plan installation so the disconnect is easily accessible for routine testing and service work, with clear pathways for lockout/tagout procedures.
• Verify wiring matches the three-phase configuration in your control circuit to ensure proper isolation and protection.
• Use the switch as the primary isolation point for motors and branch circuits to streamline safety checks during maintenance.
• In outdoor or washdown areas, ensure the enclosure remains free of obstructions and inspect seals periodically for sustained 4X protection.
