Description
GE SKLL36BD0800
Technical Specifications
- Pole Configuration: 3-Pole
- Continuous Current Rating: 800 Amperes
- Voltage Rating: 600V AC Maximum
- Interrupting Capacity: High ampere interrupting capacity (AIC) rated for heavy industrial fault currents
- Trip Type: Thermal-Magnetic or Solid-State Microprocessor Trip (depending on specific frame revision)
Functional Features
- Circuit Protection: Provides precise overcurrent and short-circuit protection to prevent equipment damage and electrical fires.
- Manual Isolation: Functions as a manual disconnect switch for safe maintenance and lockout/tagout (LOTO) procedures.
- Adjustable Trip Settings: Allows facility engineers to fine-tune the trip thresholds to match specific load characteristics.
- 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
- Mechanical Life: Tens of thousands of open/close operations.
- Electrical Life: High endurance at full rated load.
- Dielectric Strength: Withstands high-voltage spikes without breakdown.
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.
