Motorstarter

NOLTA motor starters offer optimum motor protection through:

Thermal over-stressing protection

  • No over-stressing of engine and cables

Magnetic high-speed circuit breaker

  • Quick and save disconnection in case of short circuit

Integration in plug

  • Saves costs since no extra space is required
  • Higher flexibility

Rotary field check, phase inverter and equipment-on indicator

  • Protection from incorrect engine torque direction

Automatic or manual control

  • Connections for floats or control conduit
  • Automatic restart

High resistance to short-circuits
(only at thermal-electromagnetic release)

  • No back-up fuse necessary
    (see datasheet: To Icc = 50 kA)

NOLTA – motor protection starters for one and three phase electrical motors – cost efficient due to high flexibility in application and configuration.

  • Thermo-magnetic motor protection
  • On/off switch
  • Robust polycarbonate housing
  • Combination with IEC or CEE plug con
