Description
GE SKPA36AT1200
Technical Specifications
- Part Number: SKPA36AT1200
- Pole Configuration: 3-Pole
- Continuous Current Rating: 1200 Amperes
- Voltage Rating: Up to 600V AC
Functional Features
- High-Capacity Protection: Provides robust overcurrent and short-circuit protection for large industrial loads.
- Adjustable Trip Settings: Allows facility engineers to fine-tune trip thresholds to match specific load characteristics.
- Manual Isolation: Functions as a manual disconnect switch for safe maintenance.
Application Scenarios
Main power distribution panels, large motor control centers, heavy industrial manufacturing, and commercial power infrastructure.
Performance Parameters
- Interrupting Capacity: High ampere interrupting capacity (AIC) rated for severe industrial fault currents.
- Mechanical Life: Tens of thousands of open/close operations.
Material Composition
Housed in a high-strength, flame-retardant thermoset plastic enclosure with silver-alloy contacts and copper busbars.
Structural Characteristics
Features a robust rectangular profile with external operating toggle handle, visible position indicators, and standard bolt-on connections.
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 instantly forces the contacts apart, extinguishing the 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.
- 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 to maintain mechanical lubrication.
