Need a simple way to cut the power supply to part of your circuit? Use this non-fused isolator switch from ABB to safely disconnect power for inspection and maintenance. Its compact dimensions of 68 (H) x 96 (W) x 68mm (D) mean it takes up minimal space in your setup. Thanks to a current rating of 40A, this is a suitable option for use in high-power applications. A rated impulse withstand voltage of 8kV means it can withstand sudden surges in voltage to minimise the risk of electrical damage to your equipment.

• Light weight of 310g for easy handling
• Clamp terminals ensure secure electrical connections, even in the event of heavy vibrations
• Low power loss of 1.6W per pole for energy efficiency

• Control systems
• Emergency stop push buttons
• Industrial automation

A non-fused isolator switch like this one cuts the power using a rotary switch or knife-blade disconnect, whereas a fused version uses a fuse to perform the same function.

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.
