ABB OS32GD12P Switch Disconnector Fuse, 32A 690VAC, 3-Pole DIN NH000, Mechanism Between Poles - Handle and Shaft Included

The ABB OS32GD12P is a high-reliability 3-pole switch-disconnector fuse designed for precise control and advanced overcurrent protection in industrial low-voltage applications. This model is characterized by its specialized "12" operating mechanism, which is located between the poles to provide a balanced mechanical movement and a compact footprint suitable for specific panel configurations. Engineered to accommodate DIN NH000 (000) fuse links, it serves as a robust safety solution for motor feeders and distribution branches. The product is supplied as a complete kit, including an ergonomic pistol handle and an adjustable drive shaft for front-accessible operation.

Key Features

• Centralized Mechanism (Type 12): The operating mechanism is strategically placed between the poles, optimizing the internal space and ensuring uniform contact pressure during switching.
• High Short-Circuit Resilience: Rated for a conditional short-circuit current of 100kA at 500V and 80kA at 690V, providing maximum safety during high-fault conditions.
• High Insulation & Surge Protection: Features a rated insulation voltage (Ui) of 1000V and a rated impulse withstand voltage (Uimp) of 12kV, ensuring durability against voltage spikes.
• Energy Efficient Design: Extremely low power loss of just 1W per pole at rated operating conditions minimizes heat generation within electrical enclosures.
• Versatile Connectivity: Equipped with screw terminals designed for cable cross-sections of 2.5 mm² to 25 mm², ensuring secure and low-resistance wiring.
