Abb THQC32100WL Circuit Breaker 3 Pole 100 Amp

Product Description

The ABB THQC32100WL is a 3-pole circuit breaker designed for branch-circuit and feeder protection in residential and light commercial electrical panels. It provides overcurrent and short-circuit protection for three-phase or multi-wire branch circuits, interrupting fault current to protect downstream wiring and equipment. Licensed electricians install this breaker during new construction, panel upgrades, and service replacements. The THQC series is a plug-in style breaker built for compatibility with GE and compatible load centers that accept THQC-type devices.

This breaker is suited for residential main panels, sub-panels, and light commercial distribution boards where a 3-pole, plug-in configuration is required. Typical applications include protecting large appliance circuits, HVAC equipment feeds, and three-phase or multi-wire branch circuits where a single disconnect point is needed across all energized conductors. It is installed by licensed electricians following NEC guidelines.

Key Features

• 3-pole design opens all energized conductors simultaneously for complete circuit isolation
• Plug-in mounting style for fast, tool-free installation in compatible load centers
• Thermal-magnetic trip mechanism provides both overload and short-circuit protection
• Compact form factor suited for standard residential and light commercial panelboards
• Toggle handle indicates tripped position for quick fault identification

Compatibility

Designed as an OEM-style replacement plug-in circuit breaker for load centers accepting THQC-type 3-pole breakers. Consult the panel manufacturer documentation to confirm breaker acceptance before installation.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the panel at the utility disconnect or main breaker and verify the absence of voltage with a calibrated meter before handling any conductors or breakers. Ensure the load center is listed to accept THQC-type plug-in breakers before proceeding. Do not exceed the breaker's rated ampacity when sizing connected loads.
