Abb TQD22150WL Molded Case Circuit Breaker 150A

Product Description

The ABB TQD22150WL is a thermal magnetic molded case circuit breaker from the TQD product line. It provides overcurrent and short-circuit protection in electrical distribution systems. The breaker uses a thermal magnetic trip mechanism, which responds to both sustained overloads and instantaneous fault currents. It ships complete with copper and aluminum line and load lugs, making it compatible with both copper and aluminum conductors right out of the box. Licensed electricians install this breaker in panel boards and switchboards for commercial and industrial applications.

The TQD22150WL is suited for use in electrical distribution panels where reliable overcurrent protection is required. Its integrated copper and aluminum lugs support flexible conductor selection, which is common in commercial retrofit and new construction work. The thermal magnetic design makes it appropriate for feeder and branch circuit protection in demanding environments.

Key Features

• Thermal magnetic trip mechanism provides protection against overloads and short-circuit faults
• Ships complete with copper and aluminum line and load lugs for dual conductor compatibility
• Molded case construction provides durable, self-contained housing for panel installation
• 2-pole configuration suitable for 240-volt single-phase or three-phase feeder applications

Compatibility

Designed as an OEM-style replacement or direct installation molded case circuit breaker for compatible ABB and General Electric TQD-series panel boards and switchboard assemblies accepting 2-pole, 150-amp thermal magnetic breakers.

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 and lock out the panel before installing or replacing a circuit breaker. Verify that conductor sizing and lug torque requirements match the installation specifications listed on the breaker label. Do not exceed the breaker's rated ampacity when sizing conductors or loads.
