Easily cut power supply to defined parts of an electrical circuit with this isolator switch from ABB. It allows you to de-energise individual circuits so you can safely carry out maintenance checks or repair tasks. Its adjustable mounting feet mean you can install the switch in either a horizontal or vertical position, so it's a versatile option. Clamp terminals are on hand to hold connected wires firmly, which reduces the need for regular maintenance and re-tightening. For flexible use, this device is suitable to use in an open-air environment or in an enclosure. With a power rating of 9kW, it's compatible with higher-powered systems.

• Mechanical endurance of up to 20,000 operations for an extended service life
• Low power loss per pole of 0.6W for energy efficiency
• IP20-rated housing is protected against human touch and objects larger than 12mm

• Aerospace technology
• Power-generation industry
• Pulp and paper mills
• Textile industry

This is a non-fused switch, which means you can use a rotary handle or knife blade to manually disconnect a circuit.
