Why Choose the ABB OT125TPN-A Enclosed Switch-Disconnector?
The ABB OT125TPN-A is a robust 125 A 3-pole + neutral enclosed switch-disconnector designed for reliable load switching and electrical isolation in industrial and commercial low-voltage installations. Part of ABB's metal-enclosed load-break range, it combines proven OT switch-disconnector technology with a durable steel enclosure.
The OT125TPN-A is housed in a powder-coated steel enclosure with IP65 ingress protection. Its practical enclosure design incorporates a hinged lid with lock, a padlockable pistol-grip operating handle and removable gland plates at the top and bottom, supporting straightforward installation and secure local isolation.
With a rated thermal current of 125 A and a 3-pole + neutral configuration, the OT125TPN-A is designed for three-phase installations requiring a dedicated neutral connection. At 415 V AC, the switch is rated at 125 A for AC-22 duty and 90 A for AC-23 duty, making it suitable for a wide range of distribution and machinery isolation applications.
Key Advantages
- Heavy-duty 125 A enclosed switch-disconnector for industrial applications.

Reliable Three-Phase Load Switching and Isolation
The ABB OT125TPN-A provides dependable manual switching together with a defined means of isolating downstream electrical equipment. Its 125 A rating and 3-pole + neutral configuration make it particularly suitable for three-phase distribution systems where a dedicated neutral connection is required alongside the switched phase conductors.
The IP65 steel enclosure protects the switch-disconnector against dust and water ingress, while the padlockable pistol-grip handle enables the isolator to be secured during servicing and maintenance. Removable top and bottom gland plates and the lockable hinged lid provide a practical enclosed switching solution for industrial and commercial installations.
Typical Applications
- Industrial low-voltage power distribution systems.
- Three-phase installations requiring a neutral connection.
- Main and local electrical isolation for machinery.
- Manufacturing and production equipment.
- Motor and inductive-load isolation.
- Commercial building-services installations.
- Maintenance isolation points for industrial electrical equipment.
