ABB OS32TPN - 32A, 3-Pole, Fused Disconnect Switch

Meet the ABB OS32TPN, a robust 32A, 3-Pole Fused Disconnect Switch built for reliability in demanding industrial and commercial environments. It delivers safe electrical isolation, making maintenance safe and compliant with lockout/tagout procedures, while providing dependable disconnection under load for long-term durability.

Key benefits

• Precise 32A protection for standard three-phase circuits, preventing overloads without unnecessary interruptions.
• Three-pole design ensures complete isolation of all conductors in a three-phase system.
• Integrated fusing provides immediate current interruption when faults occur, protecting equipment and wiring.
• Lockout/Tagout readiness supports safe maintenance practices and compliance with safety protocols.
• Built for durability engineered for long service life in tough environments where vibrations, dust, and temperature swings are common.

Who benefits

Ideal for facilities performing routine servicing of motors, pumps, fans, conveyors, and other three-phase equipment. Use it as a service disconnect in panels, at equipment bays, or in distribution racks where safe isolation is critical.

Practical usage scenarios

• Before motor maintenance, engage lockout/tagout and snap in the OS32TPN to ensure no energization during service.
• During system commissioning or fault isolation, rely on proven disconnection under load to safely de-energize equipment.

Why choose ABB OS32TPN over alternatives

Rather than a simple manual switch, this fused disconnect switch combines protective fusing with reliable isolation, reducing arc risk and safeguarding downstream devices. The three-pole configuration ensures all phases are safely disconnected, minimizing the chance of inadvertent energization during maintenance.
