ABB N0CH0016-62 64023063
1. Product Overview
ABB N0CH0016-62 64023063 is a low-voltage AC Du/dt filter. Designed exclusively to protect the insulation system of motors and motor cables, this product relieves insulation stress caused by pulse voltage (du/dt) and peak voltage generated by modern IGBT inverter technology, so as to effectively extend the service life of motors.

3. Product Features
- Excellent Protection Performance: It can significantly reduce voltage spike value and du/dt value at motor terminals, preventing damage to the motor insulation system.
- Cooling Method: Adopts natural convection cooling mode.
- Heat Dissipation Property: The surface operating temperature can exceed 150°C. Sufficient heat dissipation space shall be reserved during installation.
- Dedicated Design: Developed for ABB drive systems, compatible with IGBT power supply units and dynamic braking units.
- Reliable Connection Performance: Shielded cables must be used for connection between shells, and reliable grounding is required to guarantee electromagnetic compatibility (EMC).
- Cost-effective: Lower procurement cost than sine wave filters, while providing effective protection for motor insulation.
4. Structure & Composition
4.1 Mechanical Structure Components
- Inductor Coil: The core component of the filter, used to suppress the rate of voltage change.
- Copper Busbar: Internal conductive connecting component.
- Internal Circuit Structure: Equipped with filtering circuits and matching components (See internal circuit diagram in the official ABB technical manual for details).
4.2 Installation Structural Characteristics
- Lifting Holes: Reserved on the top for hoisting and transportation.
- Fixing Holes: Arranged at the bottom, fixed on the mounting surface via 4 bolts.
- Grounding Device: Connected to protective earth (PE) terminal through the mounting bracket.
5. Application Fields

ACS880 series, ACx580 series, ACS530 series, ACS380 series, ACS180 series, ACS550 series, ACS510 series, ACS355 series, ACS310 series, ACS150 series
5.2 Applicable Scenarios
- Long-distance motor cable application: Protect cable and motor insulation under long motor cable layout conditions.
- Cable length specification: Max. cable length between drive output terminal and filter: 3m; Max. motor cable length (single filter): 150m; Max. motor cable length (two filters connected in series): 300m.
- Multi-motor parallel drive occasions
- Special cable application: Applicable for special cables that generate extra operating temperature rise.
- Industrial electric drive systems: Widely applied in industrial automation, pump & fan control, conveyor systems and other industrial scenarios requiring motor insulation protection.
