Description

GE TBC43400F14G Technical Specifications:

  • Poles: 3-Pole.
  • Frame Size: 400 A Frame.
  • Continuous Current Rating: 400 A.
  • Voltage Rating: 600 VAC Max.
  • Interrupting Rating: High interrupting capacity for main distribution applications.

Functional Features:

  • Enhanced Trip Unit: Advanced thermal-magnetic or electronic trip capabilities.
  • High Fault Current Handling: Designed to safely interrupt high available fault currents.
  • Accessory Compatibility: Full range of internal and external accessories available.
  • Robust Construction: Heavy-duty frame for industrial environments.

Application Scenarios:

  • Main service entrance protection.
  • Large motor and transformer feeders.
  • Industrial switchgear and motor control centers.

Performance Parameters:

  • Precision Tripping: Accurate and repeatable trip characteristics.
  • Mechanical Endurance: Rated for thousands of mechanical operations.
  • Dielectric Integrity: Exceeds standard insulation and withstand voltage requirements.

Material Composition & Structural Characteristics:

  • Housing: High-performance thermoset or thermoplastic composite.
  • Contacts: Silver-tungsten or silver-cadmium oxide alloys for arc resistance.
  • Arc Runners: Copper or steel arc chutes for efficient arc cooling.

Working Principle: Utilizes a sophisticated trip mechanism to monitor current flow. Upon detecting a fault, the trip unit releases the stored energy in the operating mechanism, driving the contacts apart at high speed. The arc is drawn into the arc chute, where it is split, cooled, and extinguished.

Installation Requirements:

  • Heavy-Duty Mounting: Ensure the panel or switchgear is rated for the physical size and weight of the 400 A frame.
  • Busbar Connection: Verify busbar thickness and hole alignment for proper termination.
  • Clearance: Maintain strict adherence to NEC or local code clearance requirements.

Usage Precautions:

  • Professional Installation: Installation and maintenance should only be performed by qualified electricians.
  • Arc Flash: Perform arc flash hazard analysis and wear appropriate PPE when racking or operating.
  • Periodic Testing: Implement a comprehensive maintenance program including thermography and breaker testing.
