Why Choose the ABB OT160EV12P 160 A AC-23 3-Pole Switch-Disconnector?

The ABB OT160EV12P is a high-performance 3-pole switch-disconnector designed for reliable switching and isolation of industrial low-voltage electrical circuits. Part of the established ABB OT switch-disconnector range, this model is rated for 160 A AC-23A duty at 400–415 V AC, making it suitable for demanding load-switching and isolation applications.

The OT160EV12P uses a mechanism-between-the-poles configuration and is designed for front operation and base mounting. ABB supplies this P-version with a black ON-OFF plastic pistol handle and adjustable shaft as standard; the handle is IP65 protected, padlockable in the OFF position and provides door interlocking when the switch is ON.

The switch has an open-air thermal current of 200 A, with AC-22A/AC-23A operational currents of 200/160 A at 400–415 V AC. Its AC-23A operational current remains 160 A at 690 V AC, providing dependable performance for industrial machinery, switchboards and power distribution systems.

Key Advantages

  • 160 A AC-23A rating at 400–415 V AC for demanding industrial load switching.
  • 3-pole configuration for three-phase electrical systems.
  • 200 A open-air thermal current provides robust current-carrying capability.
  • AC-23A rated at 160 A up to 690 V AC.
  • Supplied with an IP65 black ON-OFF pistol handle and adjustable shaft.
  • Compact front-operated, base-mounted design for straightforward switchboard integration.

Key Features

  • ABB OT switch-disconnector series.
  • 3-pole switching configuration.
  • 200 A open-air thermal current.
  • 160 A AC-23A operational current at 400–415 V AC.
  • 160 A AC-23A operational current at 690 V AC.
  • 144 kW AC-23A operational power at 690 V AC.
  • 1000 V rated operational and insulation voltage.
  • 12 kV rated impulse withstand voltage.
  • Front-operated and base-mounted construction.
  • Mechanism located between the poles.

Reliable Switching and Isolation for Industrial Machinery

The ABB OT160EV12P provides both load-switching and isolation functionality for industrial electrical systems. Its 160 A AC-23A rating at 400–415 V AC makes it suitable for demanding inductive-load duties, while the 200 A open-air thermal current supports substantial continuous current requirements.

Its mechanism-between-the-poles arrangement, compact base-mounted construction and included adjustable shaft and pistol handle simplify integration into industrial switchboards and machinery panels. The handle can be padlocked in the OFF position, supporting controlled isolation during servicing and maintenance.

Typical Applications

  • Industrial machinery main isolation.
  • Motor and inductive-load switching applications.
  • Three-phase industrial power distribution.
  • Manufacturing and process equipment.
  • Electrical control panels and switchboards.
  • OEM machinery and automation systems.
