Product Description

Braking resistors allow Altivar Process drives to operate while braking to a standstill, by dissipating the braking energy. They enable maximum transient braking torque. Braking resistors are designed to be located outside the enclosure, but should not inhibit natural cooling. Air inlets and outlets must not be obstructed in any way. The air must be free of dust, corrosive gas, and condensation.

Standard Features

Several resistor models are available, depending on the drive rating:

  • With IP20 and IP23 casing and thermal monitoring provided by temperature-controlled switch or by the drive
  • The internal circuits of Altivar Process drives rated 220 kW/350 HP or less at 400...480 V and 45 kW/60 HP or less at 200...240V have a built-in dynamic brake transistor.
  • An external braking unit is necessary for wall-mounting Altivar Process drives above 220 kW at 400...480 V as well as 55 kW/75 HP and 75 kW/100 HP at 200...240 V.
