QOB2701021 - 70A Circuit Breaker Description
QOB2701021 - 70A Circuit Breaker
The QOB2701021 is a 70-amp, 2-pole Type QOB bolt-on circuit breaker with an integrated 120VAC shunt trip for applications where remote breaker operation is needed. Instead of having to manually switch the breaker off at the panel, the shunt trip allows it to open when it receives the proper external signal. That's why this style of breaker is often used with emergency stop stations, fire alarm systems, and building automation controls.
Beyond the shunt trip feature, this breaker provides dependable protection against overloads and short circuits in 120/240VAC electrical systems. The bolt-on mounting helps keep the breaker securely fastened in compatible panelboards, making it a common choice for commercial buildings, industrial facilities, and other locations where equipment sees daily use. Its 10kA interrupting rating gives it the capacity to safely interrupt available fault current within its rating.
Whether you're replacing an existing breaker with the same specifications or servicing an electrical distribution system, the QOB2701021 offers the combination of ratings and features needed for applications that require both circuit protection and remote tripping.
