Product Description:
The 136G7345 is a soft starter produced by Danfoss within the MCD Soft Starters series. In motor control panels it serves as a controlled-voltage device that limits starting torque and line disturbances when three-phase pumps, fans, or conveyors are energized. By managing the initial voltage applied to the motor windings, the unit minimizes mechanical shock, extends equipment life, and supports smoother automation sequences on production lines.
This model handles a continuous motor current of 579 A, so it can be placed ahead of medium-sized induction machines without external contactors. The insulation system is rated for 690 V AC, and its surge withstand capability reaches 6 kV, allowing operation on supply networks that experience switching transients. Control electronics draw 2.8 A at a user-supplied 24 VAC/VDC control voltage, and the built-in relay can switch auxiliary circuits up to 10 A @ 250 V AC. For process feedback, the analog output maintains an accuracy of ±5 % into a 600 Ω load, enabling proportional indication of motor current or ramp status to a PLC or chart recorder. The main contactor path is normally open, and an internal bypass contactor assumes the load once the start ramp is complete, reducing heat to 4.5 W per ampere during steady-state running.
The internal bypass is rated for 100000 operations, giving predictable service intervals in applications with frequent cycling. The assembly carries an IP00 enclosure classification, so it must be installed inside a protected cabinet that provides touch-safe barriers and environmental sealing. Mechanical considerations include a 19 kg shipping weight and integral mounting flanges that align with standard back-panel hardware. Three-phase power terminals accept cables sized for the 579 A duty, while the 6 kV impulse rating coordinates with upstream surge arresters and the 690 V insulation level to form a matched protection chain.
