Description
GE SKLA36AI120
Technical Specifications:
- Brand: General Electric (GE)
- Model: SKLA36AI1200
- Product Type: Electromechanical Power Contactor
- Current Rating: High-amperage industrial rating
Functional Features:
- High Inrush Capability: Engineered to safely make and break high inrush currents typical of motor and transformer loads.
- Arc Suppression: Integrated magnetic blowouts and arc chutes for rapid arc extinction and contact protection.
- Auxiliary Contacts: Provisions for snap-on auxiliary contact blocks for control circuit interlocking.
Application Scenarios:
Used in motor control centers (MCCs), power distribution panels, industrial heating systems, and large HVAC compressors.
Performance Parameters:
- Electrical Life: Hundreds of thousands of full-load operations with minimal contact wear.
- Dielectric Strength: High isolation voltage to prevent flashover between phases and to ground.
Material Composition:
Silver-cadmium oxide or silver-tin oxide contacts, phenolic arc chutes, and high-temperature coil windings with Class F or H insulation.
Structural Characteristics:
Modular design with visible contact position indicators, standardized mounting brackets, and easy-access terminal connections.
Working Principle:
Energizing the control coil creates a magnetic field that pulls the movable armature, closing the main power contacts and completing the circuit to the load.
Installation Requirements:
Mount vertically on a flat, stable surface. Ensure adequate clearance above and below for arc venting and cooling airflow.
Usage Precautions:
Torque all power connections to the manufacturer’s exact specifications to prevent overheating. Inspect contacts periodically and replace the contactor if pitting or wear exceeds limits.
