Description
GE SKLA36AT08003
Technical Specifications
- Poles: 3-Pole.
- Continuous Current Rating: 800 Amps.
- Voltage Rating: 600V AC Maximum.
- Frame Type: SKL Series.
Functional Features
- Thermal-Magnetic Protection: Provides precise protection against both prolonged overloads and instantaneous short circuits.
- Trip-Free Mechanism: Ensures the breaker trips safely regardless of the handle position during a fault condition.
- High Interrupting Capacity: Capable of safely clearing high-level fault currents.
- Visual Indication: Clear ON/OFF/TRIP status on the operating handle.
Application Scenarios
Ideal for main power feeders, large motor branch circuits, industrial panelboards, and commercial building power distribution.
Performance Parameters
- Short Circuit Rating: High interrupting capacity (e.g., 65kA at 480VAC).
- Mechanical Life: Rated for tens of thousands of manual switching operations.
- Electrical Life: Rated for thousands of full-load switching cycles.
Material Composition
Housed in a high-strength, flame-retardant glass-polyester thermoset case. Features silver-alloy contacts, copper bus bars, and precision bimetallic thermal elements.
Structural Characteristics
A compact, three-pole design with standardized line and load terminals. Features a toggle-style operating handle and provisions for internal accessories like shunt trips and auxiliary contacts.
Working Principle
Under overload conditions, a bimetallic strip heats and bends to trip the mechanism. During a short circuit, a magnetic solenoid generates a strong magnetic field that instantly unlatches the mechanism, separating the contacts and extinguishing the arc.
Installation Requirements
Must be installed in a compatible panelboard or enclosure. Line and load terminals must be tightened to the manufacturer’s specified torque values. Ensure proper phase rotation and grounding.
Usage Precautions
Never bypass or tie down the breaker handle. Do not use as a routine disconnect switch for normal operations. Always de-energize the panel before installation and verify zero energy before maintenance.
