Description
GE TED134125
- Technical Specifications:
- Current Rating: 125 A
- Voltage Rating: 480 V AC (Maximum 600 V AC)
- Number of Poles: 3
- Interrupting Capacity: 18 kA at 480 V AC
- Trip Type: Thermal Magnetic (LI – Long-Time and Instantaneous)
- Connection Type: Bolt-On
- Functional Features: Utilizes a rugged molded case for mechanical strength; combines thermal bi-metal elements for overload protection and magnetic solenoids for instantaneous short-circuit response; compatible with GE bolt-on mounting systems for secure installation.
- Application Scenarios: Industrial facility distribution panels, commercial building service entrance substations, three-phase motor feeder protection, and general low-voltage power distribution networks.
- Performance Parameters: Rated for operation at 60/75°C conductor temperature; suitable for reverse feed applications; supports Cu/Al wiring.
- Material Composition: Outer shell constructed from high-impact flame-retardant thermoplastic; internal contacts made of silver alloy for arc resistance; operating mechanism composed of high-strength composite alloys.
- Structural Features: Compact 3-pole frame design; bolt-on tabs for direct panel mounting without adapters; front-operated toggle handle for ON/OFF control; visible trip flag indicator.
- Working Principle: Under overload conditions, heat generated by excessive current causes a bimetallic strip to deflect and trip the mechanism after a time-inverse delay. Under short-circuit conditions, electromagnetic force instantly attracts a plunger to release the latch and open the contacts, interrupting current flow.
- Installation Requirements: Must be installed in compatible GE bolt-on style panel boards; torque lug connections to manufacturer specifications (typically 4-1/8 inch spacing considerations); ensure phase alignment and proper grounding of the enclosure.
- Usage Precautions: Never operate with the cover removed while energized; verify system voltage matches rating before installation; do not exceed 125 A continuous current without derating; test mechanical operation periodically in harsh environments.
