AUC3 Series AUC3-06C ~ 38C AC Contactors

Product Overview

AUC3-06C ~ 38C AC contactors are mainly applied in circuits with AC 50Hz/60Hz frequency, maximum rated operational voltage up to 690V, and rated operational current ranging from 6A to 38A under utilization category AC-3, for the control of AC motors. They can be combined with matched thermal overload relays to form electromagnetic starters, providing protection for circuits prone to operational overload.

Product Features

- High-performance silver alloy contacts with long electrical service life
- Wide pull-in voltage range, enabling reliable operation even with grid voltage fluctuations
- Class H high-temperature resistant enameled wire for enhanced coil durability
- The coil supports top incoming wiring and top-bottom dual wiring to meet various customer wiring requirements
- Optimized buffer structure reduces noise of the electromagnetic system
- Equipped with top dust cover and side dust stickers for superior dustproof performance
- Compact miniaturized design with smaller overall dimensions

Structural Features

- Building-block modular design allows installation of auxiliary contact modules, thermal relays and other accessories to fit various application scenarios
- Main and auxiliary contacts are arranged on the same layer, reducing overall height and saving installation space
- Two coil wiring options available: top-inlet wiring and top-bottom dual inlet wiring to satisfy diverse customer wiring requirements
- Two mounting methods supported: standard 35 mm DIN rail mounting or screw fixing; dimensions are interchangeable with similar competing products

Product Applications

Widely used in machinery manufacturing, chemical industry, electric power, elevators, air conditioners, water pumps, conveying machinery and other industries; also suitable for other application scenarios such as lighting control, heating equipment and electric locomotives.
