Description

GE SGLC3604L4XX

Technical Specifications

  • Part Number: SGLC3604L4XX
  • Pole Configuration: 4-Pole
  • Continuous Current Rating: 400 Amperes (Typical for this frame size)
  • Voltage Rating: Up to 600V AC

Functional Features

  • Circuit Protection: Provides precise overcurrent and short-circuit protection to prevent equipment damage.
  • Manual Isolation: Functions as a manual disconnect switch for safe maintenance and lockout/tagout (LOTO) procedures.
  • Arc Chute System: Internally designed to safely extinguish high-energy electrical arcs during a fault condition.

Application Scenarios
Extensively used in main power distribution panels, heavy industrial manufacturing plants, large motor control centers (MCCs), and commercial power infrastructure.

Performance Parameters

  • Interrupting Capacity: High ampere interrupting capacity (AIC) rated for heavy industrial fault currents.
  • Mechanical Life: Tens of thousands of open/close operations.

Material Composition
Housed in a high-strength, flame-retardant thermoset plastic enclosure. Internal components include silver-alloy contacts, copper busbars, and precision bimetallic strips or electronic sensing coils.

Structural Characteristics
Features a robust, compact rectangular profile with standard rear or front bolt-on connections, external operating toggle handle, and visible ON/OFF/TRIPPED position indicators.

Working Principle
Under normal conditions, the breaker maintains a closed electrical path. During an overload, thermal elements heat up and bend to trip the mechanism. During a short circuit, the magnetic field generated by the massive current instantly forces the contacts apart, extinguishing the resulting arc within the arc chute.

Installation Requirements

  • Must be mounted vertically in a standard NEMA or IEC rated enclosure.
  • Line and load connections must be torqued strictly to GE specifications using a calibrated torque wrench.
  • Ensure adequate clearance for arc flash safety and heat dissipation.

Usage Precautions

  • Always perform Lockout/Tagout (LOTO) procedures before servicing.
  • Never operate the breaker beyond its rated voltage or current capacity.
  • Periodically exercise the breaker (open and close) to maintain mechanical lubrication and prevent contact oxidation.
