Description
1. Product Overview
The two models of ABB 23070 series, 23070‑0‑102201100000 and 23070‑0‑101112100000, are dedicated filter capacitors for industrial electrical systems, automation drives, high‑voltage frequency converters and precision industrial control equipment. They are core OEM spare parts of ABB. As industrial‑grade high‑voltage durable capacitor units, they feature voltage stabilization & filtering, harmonic suppression and voltage compensation for circuit protection. Widely compatible with ABB frequency conversion systems, servo control systems, low‑voltage power distribution units and industrial precision electric control equipment, they serve as key passive components to stabilize system voltage, mitigate electromagnetic interference and extend service life of industrial‑control devices.
Sharing the standardized 23070‑series design philosophy, both models adopt high‑temperature resistant, anti‑aging and low‑loss capacitor dielectrics for 7×24‑hour continuous industrial operation. Their main differences lie in capacitance rating, withstand voltage and applicable load conditions. One is for light‑load precision filtering and the other for heavy‑load high‑voltage voltage stabilization. Featuring good universality and application‑specific performance, they are extensively used for maintenance replacement and technical retrofit of new and legacy ABB industrial‑control equipment, with outstanding advantages of high stability, ultra‑low loss, surge resistance, long service life and high compliance.

3. Functional Features
High‑efficiency filtering and noise reduction for electrical‑circuit conditioning Both capacitors effectively filter high‑frequency grid noise, harmonic interference and voltage spikes. They resolve common issues including signal drift, data fluctuation, servo jitter and false alarms of frequency converters. They condition power‑supply and signal circuits to guarantee accuracy and stability of electrical equipment.
Dynamic voltage compensation for stable system operation They compensate for instantaneous voltage drop and grid fluctuation in real time and balance voltage deviation within circuits. They prevent abnormal start‑stop, unstable load performance and module shutdown caused by poor voltage quality, suitable for harsh industrial sites with severe grid fluctuations.
Surge resistance and anti‑aging performance for continuous operation Built with high‑purity imported capacitor dielectrics and flame‑retardant hermetic encapsulation, they deliver excellent resistance against voltage surges, current impulses, high temperature and aging. Capable of enduring high temperature, humidity and heavy electromagnetic interference in workshops, they support 7×24‑hour non‑stop operation with long maintenance‑free service intervals.
Low loss and low temperature rise for safe and reliable operation Optimized dielectric material and internal structure reduce dielectric loss and operating temperature rise significantly. Potential failures such as overheating bulging, breakdown and short‑circuit are avoided. With low risk of spontaneous combustion and electric leakage, they satisfy safety requirements for continuous industrial production.
- Application‑oriented design for differentiated working conditions The standard‑version unit ensures signal stability for precision weak‑current and light‑load loops; the enhanced‑version unit improves system surge‑resistance for high‑power, heavy‑load and high‑voltage‑fluctuation scenarios. The two models cover capacitor‑matching requirements of full‑range ABB industrial‑control, drive and frequency‑conversion equipment.

Fully‑sealed flame‑retardant packaging with superior protection performance Constructed with flame‑retardant industrial housing plus full potting encapsulation, the units resist dust, moisture, oil contamination and corrosion. They prevent insulation degradation, electric leakage and short‑circuit resulting from ingress of moisture and dust, suitable for harsh workshop environments.
Advanced dielectric technology for consistent performance High‑precision film‑capacitor dielectrics ensure tight capacitance consistency and minimal temperature drift. Electrical parameters show negligible degradation under wide temperature variation. Long‑term operation maintains stable performance without filtering failure or voltage‑stabilization deviation.
Compact standardized design for easy installation Modular compact form factor fits built‑in mounting positions of standard industrial cabinets and frequency converters. Standardized terminals simplify installation and wiring layout for various ABB complete electric‑control assemblies.
