Description
Product Overview
THED136100WL is a 3-pole high interrupting capacity molded case circuit breaker within GE E150 THED series. It provides thermal-magnetic overcurrent protection for industrial 3-phase power distribution circuits, protecting loads and wiring against overload and short-circuit faults. This breaker is widely deployed in power plant auxiliary cabinets, substation control panels and factory main distribution boards. GE discontinued original production; available stock is new surplus or fully tested reconditioned spare units.

Key Features
- Thermal-Magnetic Dual Trip Protection: Thermal element responds to long-time overload; magnetic element trips instantly for short-circuit faults.
- High Short-Circuit Interrupt Rating: Designed for locations with high available fault current in industrial power systems.
- Bolt-on Terminal Design: Secure connection for heavy industrial wiring, suitable for fixed cabinet installation.
- Compact E150 Frame Size: Saves cabinet panel space while delivering robust protection.
- Clear Front Operation Toggle: ON/OFF handle with visible trip indication; red trip reset button.
- Wide Industrial Compatibility: Used for motor feeders, transformer secondary circuits and auxiliary power distribution.
- Legacy Power Distribution Spare: GE stopped manufacturing this model; used for maintenance replacement of existing power panels.
Applications
- Power station auxiliary power distribution cabinets
- Substation low voltage distribution boards
- Petrochemical plant MCC motor feeder circuits
- Manufacturing factory main and branch power panels
- Data center and large commercial building distribution retrofits
Installation & Maintenance Notes
- Execute lockout-tagout procedure before removing or installing the breaker.
- Verify cable lug torque to avoid loose connections and overheating.
- Confirm short-circuit withstand rating matches site fault current level.
- Inspect breaker contacts and insulation periodically; check for overheating marks on terminals.
- After short-circuit trip, test breaker function before re-energizing; replace if internal damage detected.
- Confirm full part number match when replacing spare breaker, verify pole count, amp rating and voltage class.
FAQ
Q: What does THED stand for? A: THED = GE high interrupting molded case breaker series, E150 frame family.
Q: Does THED136100WL have ground fault protection? A: Standard version does NOT include built-in ground fault trip; GF module can be added as an optional accessory.
