Allen-Bradley 140G-G2C3-C60 Molded Case Circuit Breaker 60A

Product Overview

The Allen-Bradley 140G-G2C3-C60 is a G-Frame Molded Case Circuit Breaker engineered for high-reliability power distribution and motor protection. It features a robust 125 Amp nominal frame with a fixed 60 Amp operational limit. Designed for efficiency, this compact MCCB combines fixed thermal and magnetic protection mechanisms to safeguard electrical systems from damaging overcurrent events and short circuits. Its durable construction is specifically optimized to withstand the rigors of harsh industrial environments while maintaining a space-saving footprint in control panels.

Core Technical Advantages

Advanced Circuit Protection

The 140G-G2C3-C60 utilizes a fixed thermal-magnetic trip system, providing consistent and predictable response times to electrical faults. This dual protection approach ensures that both slow-acting overloads and instantaneous short circuits are handled effectively, maintaining the safety of downstream equipment.

High Electrical Integrity

Built to manage high-voltage transients, this breaker boasts an 800V insulation voltage rating and an 8kV impulse withstand voltage. These specifications ensure that the device remains operational and safe even during significant voltage surges or fluctuations common in heavy industrial settings.

Compact G-Frame Design

The space-saving structure of the G-Frame series allows for higher density mounting in electrical enclosures. Despite its small size, it maintains a 25 kA interrupting capacity, delivering powerful performance without requiring excessive cabinet real estate.

Technical Specifications

Installation & Operation Notes

• Mounting: Ensure the MCCB is securely mounted on a flat surface or DIN rail (if compatible) to prevent mechanical stress on terminal connections.
• Controls: Features user-friendly toggles and simplified controls for effortless resetting and status monitoring.
• Environment: Designed to withstand harsh industrial conditions; however, ensure adequate ventilation within the enclosure for optimal thermal performance under continuous load.

Technical FAQs

Q1: What does the "Fixed" protection indicate?

A1: It means the thermal and magnetic trip settings are factory-set at 60 Amps and cannot be adjusted in the field, ensuring consistent protection levels without the risk of accidental tampering.

Q2: Can this breaker be used for global applications?

A2: Yes, the 140G series is generally designed to meet major international standards (UL/CSA and IEC), though you should verify specific compliance for your region.

Q3: Why is the Impulse Withstand Voltage (8kV) important?

A3: This rating indicates the breaker's ability to resist high-voltage spikes (like lightning strikes or switching surges) without insulation failure, significantly enhancing overall system reliability.
