Use this isolator switch from ABB to safely disconnect appliances on a DIN rail. With a front-operated knob actuator, it instantly isolates its connected circuits to allow you to service and maintain rail-mounted components. The switch features 4 poles to control up to 4 circuits, making more hardware available for examination at once. Designed with compact dimensions of 68 (length), 48 (width) and 56mm (depth), the switch fits neatly into your electrical system to maximise packing density on your DIN rail.

• DIN rail mounting for easy installation and relocation when needed
• Resists impulse voltages up to 8kV to handle sudden heavy electrical loads
• Screw termination ensures reliable electrical connections during operation and simple swapping when changing components

• Switchboards
• Automotive manufacturing
• Energy industry

Impulse voltages rise to a peak value and then drop quickly. Some applications with unpredictable power supplies occasionally experience impulse voltages, meaning they need components that withstand those voltages and keep working afterwards. As a safety device, it's especially important that an isolator switch continues working as intended to keep operators safe.

The OT range of switch disconnectors are suitable for use in a variety of applications including motor control centres, switchboards and as main switches in machines.
