This document introduces the Siemens 3VL family of molded case circuit breakers, which are characterized by using the fewest number of components to provide the most functions, complying with international standards, and being able to change component configurations according to task requirements.
The Siemens 3VL family of molded case circuit breakers offers high adaptability with a wide range of rated currents from 16A to 1600A. Inspired by the flexibility of Chinese Tangram puzzles, this series is designed using minimal components to achieve maximum functionality while meeting and exceeding major international standards.
The product supports various tripping unit types (thermal-magnetic, electronic), pole configurations, and accessory setups for line protection and motor/generator protection. The document provides detailed ordering code structures and selection tables to assist users in choosing the correct model. This manual is written in Chinese.
The product covers a rated current range from 16A to 1600A.
The short-circuit breaking capacity is rated at 40/45/50kA.
The undervoltage release supports DC voltages of 12V, 24V, and 48V.
