Keep your system on the straight and narrow with this non-fused isolator switch from ABB. It's an essential piece of kit used to cut the power supply to isolated parts of a circuit to allow for maintenance. Thanks to a high operating temperature of +40°C, there's no chance of it overheating under normal working conditions. Compact dimensions of 68 (L) x 56 (D) x 48mm (W) mean it fits a small enclosure, or a tightly packed DIN rail, without issue. As there's no fuse, this device calls for minimal maintenance.

• Clamp terminals for simplified assembly, without the need for screws or fasteners
• IP20-rated front indicates it's finger-safe and protected against objects over 12mm
• Snaps onto a DIN rail for easy mounting
• Voltage rating of 750V means it's ideal for high-power applications
• High 8kV rated impulse withstand voltage ensures it withstands a high-voltage surge or transient event without being damaged

• Marine industry
• Motor control maintenance
• Oil and gas facilities
• Power distribution

This isolator switch has a mechanical durability of 20,000 cycles, so it's built to last.

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.
