3NA3230-2C

Updated: 2026-07-20

Overview

The 3NA3230-2C is a molded-case circuit breaker (MCCB) designed for industrial and commercial electrical systems. It provides reliable protection against overloads and short circuits, ensuring the safety and longevity of electrical equipment. Manufactured with high-quality materials, this circuit breaker is known for its durability and performance under demanding conditions. Circuit breakers like the 3NA3230-2C are critical components in electrical distribution networks. They automatically interrupt current flow when a fault is detected, preventing damage to wiring and connected devices. This model is widely used in factories, data centers, and other high-power environments.

Structure and Working Principle

The 3NA3230-2C features a robust thermoplastic housing that encloses metal contacts and a tripping mechanism. The breaker operates based on thermal-magnetic principles: the thermal element responds to prolonged overcurrents, while the magnetic element reacts instantly to short circuits. Inside the breaker, a bimetallic strip bends when heated by excessive current, triggering the trip mechanism. For short circuits, a solenoid generates a magnetic field that forces the contacts apart. This dual-action design ensures quick and reliable protection under various fault conditions.
