Description
Product Overview
The ABB KVC757A124, identified by order number 3BHE020959R0124, is listed by industrial spare-parts suppliers as an IPS power-related board used in ABB drive equipment. The KVC designation is associated with power-electronics subprints rather than conventional PLC input/output modules. For maintenance teams, that distinction matters: the correct replacement must match the drive’s internal power architecture, board revision, and original parts documentation—not simply a similar-looking circuit board.
A related ABB model, KVC757A, is described as an IPS single-voltage 27 V board associated with ACS2000 drive spare parts. This provides useful context for identifying the product family, but it does not independently establish every electrical specification or compatibility claim for KVC757A124.
Before purchasing, compare the complete order code, board markings, connector arrangement, and hardware revision with the installed component. If the drive is part of a critical production or power-generation process, verify the replacement against the equipment-specific documentation before installation.
For procurement, ABB KVC757A124 should be sourced as a model-specific drive spare. Request clear photographs of the nameplate and both sides of the board, confirmation of the stated order number, and a written description of its condition. For used or refurbished stock, ask whether the unit has undergone electrical inspection and functional testing. These checks help reduce the risk of receiving a related but incompatible KVC-series board, particularly when older drive hardware is being maintained after the original installation documentation has become difficult to obtain.
Product Introduction
A wrong power-electronics board can turn a planned drive repair into an extended outage. The ABB KVC757A124, order number 3BHE020959R0124, is identified in supplier listings as an IPS power-related spare. Confirm the full part number and drive compatibility before ordering; related KVC models are not automatically interchangeable.
For replacement planning, prioritize verified markings, revision matching, and documented inspection. The exact electrical ratings and supported drive configuration for this variant should be confirmed from ABB documentation or the installed equipment’s parts list.

Frequently Asked Questions
Q1: What is the ABB used for?
Supplier listings identify it as an IPS power-related board with order number 3BHE020959R0124. Confirm its exact role and installation position using the drive’s technical documentation before replacement.
Q2: Is the same as KVC757A?
Not necessarily. is listed with a different order number, 3BHE020959R0127. The requested is associated with 3BHE020959R0124. Match the complete order number rather than relying on the base designation.
Q3: Can replace KVC758A124?
Do not assume so. KVC758A124 is listed as a dual-voltage subprint, while is associated with a single-voltage design. Differences in power architecture can make substitution unsafe or prevent proper operation.
Q4: What voltage does require?
A related listing refers to a single-voltage 27 V supply. The exact electrical ratings of have not been independently verified. Check the original board label and applicable documentation before energizing it.
Q5: Can this board be hot-swapped while the drive is running?
Do not hot-swap it unless ABB documentation explicitly permits that procedure for the installed drive and board position. Follow the drive’s isolation, stored-energy discharge, and electrical-safety requirements.
Q6: What should I request when buying a replacement?
Ask for photographs showing the complete part number, ABB order code, revision markings, connectors, and board condition. For refurbished stock, request test records and details of the inspection performed. Confirm warranty terms and return conditions in writing.
Q7: How can I confirm compatibility before ordering?
Compare the full order number against the drive’s bill of materials or original parts list. If documentation is incomplete, provide the supplier with the drive model, serial or type information, installed board markings, and clear photographs. Obtain written confirmation that the offered unit matches the required configuration.
