ABB Isolator Switch, 4 Poles, Base Mounting Design - OT Series - OT125F4C 1SCA105054R1001

Want to be sure of safety during machine maintenance? Trust this ABB isolator switch to turn off the power. When combined with a shaft and handle, it forms a reliable assembly that lets you cut electricity to defined sections of a system, making them safe to work on. An insulation voltage of 750V and an impulse withstand voltage of 8kV means you can use the unit with demanding systems. It's a four-pole device that helps streamline your setup, as you can disconnect up to four circuits using a single isolator.

Features & Benefits

• Accepts cables in a broad cross-section range between 10 and 70mm² for flexibility

• Front side has an IP20 rating, so it's touch-proof and protected against small tools larger than 12mm

• Narrow depth of 86mm shows it's suitable for mounting in recesses and other tight work areas

• 6.3W power loss per pole for energy efficiency

• 1.2kg weight means it's easy to handle during installation

Applications

• Power distribution systems

• Renewable energy sector

• HVAC equipment

• Manufacturing industry
