Allen Bradley 140G-G3C4-C20

The Allen-Bradley 140G-G3C4-C20 is an advanced, compact Molded Case Circuit Breaker (MCCB) from the versatile 140G series. It is engineered to deliver reliable overcurrent protection for a broad spectrum of industrial, commercial, and power distribution applications.

This model, built on the G-Frame, features a 3-pole configuration, making it suitable for protecting three-phase electrical circuits. Its nominal current rating is 20A, which is ideal for safeguarding smaller motors, transformers, and feeder lines.

At the core of the breaker is a modern LSI electronic trip unit. This unit provides three adjustable protective functions:

• L (Long-Time): Protects against overload conditions with a time-delay setting.
• S (Short-Time): Protects against short-circuits with a short time delay, allowing for system coordination and selectivity.
• I (Instantaneous): Provides instantaneous protection against high-level short-circuit currents.

The electronic trip unit allows users to precisely tailor the breaker's performance characteristics to the specific requirements of the protected circuit, significantly enhancing the safety and reliability of the installation.

The 140G-G3C4-C20 breaker has a Standard Interrupting Capacity rated at 35 kA at 480V AC. This rating is sufficient for most standard industrial and commercial applications.

The product complies with global standards, including UL, CSA, and IEC, facilitating its implementation in projects worldwide. Like other products in the 140G series,...
