Description
GE TED134150WL
- Technical Specifications:
- Current Rating: 150 A
- Voltage Rating: 480 V AC (Max 600 V AC, 500 V DC)
- Poles: 3
- Interrupting Rating: 18 kA at 240/480 V AC, 14 kA at 600 V AC
- Trip: Thermal Magnetic (LI)
- Terminal: Cu/Al line and load lugs
- Functional Features: Fixed thermal-magnetic trip unit; reverse feed capable; bolt-on or plug-in compatibility depending on panel; lug terminals accept large gauge wiring; flame-retardant molded case.
- Application Scenarios: Main feeder breakers in commercial MCCs, industrial sub-distribution panels, large motor branch circuits, HVAC system protection.
- Performance Parameters: Mechanical/electrical endurance per UL 489; calibrated for 60/75°C conductor rating above 100A; suitable for 3-phase 4-wire Wye or Delta systems up to 480 V.
- Material Composition: Thermoset polyester resin molded case; silver-cadmium oxide contacts; bimetal overload element; copper alloy lug bodies with tin plating.
- Structural Features: Three-pole stacked frame with integrated lug wells; front toggle with trip indicator flag; mounting feet for bolt-on panels; clear marking of line vs. load side (though reversible feed allowed).
- Working Principle: Overloads heat the bimetal strip causing deflection over time (inverse time curve); short-circuits generate magnetic flux in the solenoid exceeding spring tension, instantaneously releasing the latch to separate contacts and extinguish the arc in arc chutes.
- Installation Requirements: Use correctly sized torque wrench for lug terminals (accommodates 4 AWG–500 KCMIL); ensure breaker is fully seated in panel rail; confirm phase sequencing and neutral (if used) isolation.
- Usage Precautions: Do not exceed 150 A continuous load without ambient temperature derating; periodically check lug tightness as aluminum expands/contracts; ensure arc chutes are intact when inspecting during maintenance.
