Product Description:

The 132H2225 belongs to the MCD Soft Starters series manufactured by Danfoss. As a solid-state soft starter, it is installed between the mains and an AC induction motor to limit inrush current and mechanical stress during ramp-up and ramp-down. Designed for three-phase power networks, the device is used across conveyor, pump, and fan applications where gradual acceleration improves equipment life and reduces line disturbances.

This model handles a continuous motor current of 215 A and supports a normal-duty output of 125 hp when the supply is 480 V. For insulation coordination, its impulse withstand capability is rated at 6 kV, and its main terminals are insulated for up to 690 V AC. The open-chassis construction carries an IP00 ingress rating, so the unit must be fitted inside an enclosure that provides the required protection. An internal bypass contactor is not fitted, allowing an external bypass scheme to be used when continuous-run efficiency or heat reduction is important. The starter accepts three-phase input only and offers an analog output that can drive instrumentation loads down to 600 Ω for process feedback. Relay A is supplied in a changeover form to provide run status or fault signaling.

Control connectivity is handled through a logic input that recognizes 24 V DC signals, simplifying interface with common PLC output cards. The programmable relay output can switch up to 10 A @ 250 V AC resistive, enabling direct actuation of contactors or alarm beacons. Mechanical dimensions correspond to Frame Size 2, so panel layouts can match other Danfoss starters of similar rating. Under heavy-duty classification, the starter supplies 100 hp at 480 V, with a thermal rating of 143 A based on NEMA guidelines, while normal duty allows 176 A. The device omits an internal bypass but retains programmable ramp profiles that coordinate voltage reduction with load characteristics.
