ABB Magnetic Circuit Breakers Editorial Review

  • ubuy Montserrat

The General Electric THQL21100 Thick Series 2-Pole 100-AMP Circuit Breaker is a reliable and versatile choice for circuit protection. It is not a main breaker and is best used as a supplementary breaker. The THQL and THQP breakers are interchangeable and can be used in the same panel. The difference between THQL21100 and TQAL21100 is simply the age. The breaker is manufactured in the United States with some parts manufactured in China. It is compatible with Siemens and Eaton BR panels. It accepts wire sizes from 6 to 1/0 AWG for copper and 4 to 1/0 AWG for aluminum.
