The Simplex Load Cube Resistive/Reactive Load Bank offers ultra-large capacity testing, maintenance, and performance proving of large generating systems. The Load Cube is rated 3125 KVA 0.8 pf (2500 kW resistive, 1875 KVAR inductive) at 400-600V AC commercial voltages.


  • Numerous Applications: Testing large diesel generators, turbines, paralleled generators and shipboard generators. Ideal for rental use.
  • Load Elements: Simplex Powr-Web chromium alloy, open wire, continuously supported, power resistor; Rack mounted inductive load elements.
  • System Controls: PLC based digital load control; Remote operator interface terminal and user programmable automatic test routines.
  • Cooling: Approximately 60,000 CFM divided by two cooling fans; Power operated intake and exhaust louvers with protective screen; Forced air cooling with horizontal airflow.
  • System Protection: Sensors, alarms (alarm message on remote operator interface terminal), lock-outs as appropriate, for the following: fan failure, high exhaust temperature, high intake temperature, high interior temperature (sensed at three points).
  • Load Circuit Protection: branch circuit fuses. One set of fuses each 50KW branch. Fuses are current limiting type, 200,000 AIC, 600V, enabling safe use on large generating or UPS system.
  • Element Circuit Protection: Branch circuit fuses: 50KW each, resistive branch circuit max; 75KVAR inductive branch circuit max; 600V 200KAIC current limiting type.
  • Load Control: 3-Pole magnetic contactors; Branch circuit contactors, each 50KW resistive circuit max or each 75KVAR inductive circuit max. Inductive circuits are double break. Contactors have enclosed silver surfaced contacts, 120V coils (electrically operated and electrically held).
  • Connections: Control Wiring: 105°C, color coded; Power Wiring: 150°C XLP color-coded.
  • Power: Control Wiring: connection to plug-in connectors located within recessed side well; Control Power Supply: Dual voltage control power transformer with supply power switchable to internal (generator) or external; Power cable connection behind hinge-up door. Cables connect to full rated copper bus bar.
  • Duty Cycle: Continuous.
  • Enclosure: Type 3R weatherproof construction suitable for all-weather transport and use; Portable, self-contained: lifting eyes, forklift channels, heavy skid base, and suitable for direct transport by standard flat bed truck; Four-sided service access via hinged doors with lockable, flush latches; Rugged, all-welded, tubular steel frame, heavy gauge steel sides, guarded hinged doors, power-operated ventilation louvers.
