Product Description:

Danfoss produces the 132H2240, a solid-state soft starter that belongs to the MCD Soft Starters series. The unit sits between the main contactor and an AC induction motor, controlling the initial voltage ramp so mechanical stress and inrush currents are reduced during startup. In automated plants, its gradual acceleration function lowers electrical peaks on feeders, protects gearboxes, and helps minimize downtime associated with abrupt motor energization. That controlled ramp is useful on systems where belts, couplings, and pump lines can be damaged by full-voltage starts.

The 132H2240 occupies frame size 2, which sets its mounting footprint and terminal spacing for switchboard integration. It can be connected to mains supplies from 380 V AC up to 690 V AC. The power section is rated for 275 A of continuous line current, allowing it to handle substantial motor loads in compatible systems. The power circuit uses three-phase power, so it is intended for standard industrial motor systems. This current range suits larger pumps, fans, and conveyors that need reduced mechanical shock at startup. The wide supply range makes the starter suitable for installations fed from different industrial distribution voltages without changing the basic device type.

The unit has no internal bypass, so the SCRs remain in the current path during operation unless an external bypass arrangement is added. With a protection class of IP00, the device must be installed inside a separate enclosure to prevent accidental contact with live parts. Its enclosure volume is 59.4 L, which is useful when planning cabinet space and airflow. Because there is no touch protection at the unit itself, the surrounding cabinet must provide the required shielding for safe operation. It is part of the VLT Soft Starter MCD product group.
