Product Description:
The 136G7354 is a solid-state motor controller produced by Danfoss for the MCD Soft Starters series. Connected between the mains and a three-phase induction motor, it applies controlled voltage ramps to limit mechanical shock, water hammer, and electrical disturbance during start and stop cycles. This makes the unit suitable for conveyor sections, centrifugal pumps, and fan drives that benefit from smoother acceleration and deceleration. By reducing abrupt current draw at startup, it also helps connected equipment begin motion with less stress on driven components.
Its heavy-duty current capacity is 527 A, allowing it to regulate large motors without external contactors. The main circuit insulation withstands 690 V AC, so the starter can be used on systems that operate on standard 400 V or 480 V supplies. An analog monitoring channel offers feedback with ±5% accuracy into loads of 600 Ω, allowing a PLC or other control system to receive a stable signal during operation. The control logic draws 600 mA from a dedicated low-voltage supply, which helps isolate the electronics from disturbances on the power line. During short-circuit events, the thyristor stack can withstand an energy let-through of 781000 A²s, which is useful when selecting upstream protective devices.
The device is delivered in frame size 2 and uses an internal bypass system that diverts current around the SCRs once full speed is reached, which helps reduce heat losses during steady operation. Emissions comply with Class B limits, and the open-chassis design carries an IP00 rating, so the unit must be installed inside an enclosed control panel. Power lugs accept a tightening force of 66 Nm, providing a secure electrical connection for copper busbars that carry three-phase power. A programmable relay interface rated at 10 A and 250 V AC can forward run, trip, or status signals to plant controls. This arrangement allows the starter to share operating and fault information with surrounding control equipment during normal machine operation.
