Description
GE TKMA2Y1000
Technical Specifications
- Frame Type: TKM Series
- Amperage Rating: 1000 Amperes
- Poles: 2 Poles
- Voltage Rating: 600V AC Maximum
- Interrupting Rating: High short-circuit interrupting capacity tailored for 240V, 480V, and 600V AC systems.
Functional Features
- Provides robust thermal-magnetic protection against overloads and short circuits.
- Features aluminum/copper load and line lug terminal types for versatile wiring compatibility.
- Engineered for field replacement, retrofits, and system expansions.
Application Scenarios
Extensively utilized in main power distribution panels, heavy industrial manufacturing facilities, and large commercial infrastructure requiring high-amperage circuit protection.
Performance Parameters
- Capable of handling massive fault currents safely.
- Precision-engineered trip mechanisms ensure accurate and fast response to electrical faults.
Material Composition
Housed in a high-strength, flame-retardant thermoset plastic enclosure with high-conductivity copper/aluminum internal busbars and silver-alloy contacts.
Structural Characteristics
Compact molded case design with standardized dimensions for seamless integration into existing switchgear and panelboards. Features an external toggle handle for manual operation.
Working Principle
Operates using a thermal-magnetic tripping mechanism. The thermal element responds to sustained overloads via a bimetallic strip, while the magnetic element provides instantaneous tripping during severe short-circuit conditions.
Installation Requirements
- Must be installed by qualified electricians in accordance with local electrical codes.
- Requires proper torque specifications on line and load lugs to prevent overheating.
- Ensure adequate ventilation and clearance around the breaker for heat dissipation.
Usage Precautions
- Always de-energize the panel before installation or maintenance.
- Never exceed the rated voltage or amperage capacity.
- Perform regular maintenance testing to ensure mechanical and electrical integrity.
