Why Choose the GA125A?

The Lovato GA125A is a 3‑pole switch disconnector designed for reliable AC isolation in industrial panels. This direct operating version delivers 125 A Ith and a 1000 V rated insulation voltage, with 8 kV impulse withstand for robust performance. Flexible installation allows screw fixing on a plate or 35 mm DIN rail. Frontal IP20 protection and Pollution Degree 3 support safe operation during commissioning and maintenance.

Performance is proven across duties: AC-21A up to 125 A at 400–690 V, AC-22A to 125/100/47 A, and AC-23A to 125/100/47 A with operational power to 55 kW at 400 V. With 50 kA conditional short-circuit current (gG125 fuse), 30,000-cycle mechanical and electrical life, 5–6 Nm terminals for 4–70 mm² conductors, and operation from −25 to +55 °C up to 3000 m, it complies with IEC/EN 60947-3/-1 and UL98.

Key Benefits

  • 3‑pole AC isolation with 125 A Ith for demanding industrial loads.
  • Direct operating version for simple, positive disconnection at the device.
  • High insulation margin: Ui 1000 V, Uimp 8 kV for resilience.
  • Flexible mounting on 35 mm DIN rail or screw-fixed plate.
  • Strong short-circuit performance: 50 kA with gG125 fuse protection.
  • Long service life: 30,000 mechanical and AC-21A electrical cycles.
  • Frontal IP20 protection and Pollution Degree 3 for safer handling.
