HB2B090 - 90Amp Circuit Breaker

HB2B090 - 90Amp Circuit Breaker

The Siemens HB2B090 is a 90 Amp, 2-pole molded case circuit breaker designed for branch circuit protection in compatible Siemens HBQ (BQ) bolt-on panelboards. Built for 120/240 VAC electrical distribution systems, this breaker features a 65kA interrupting capacity (AIC) to help protect circuits from overloads and short circuits. Whether you're replacing an existing breaker as part of routine maintenance or servicing an established electrical system, the Siemens HB2B090 offers the proper form, fit, and functional replacement when the original specifications call for a 90 Amp, 2-pole HBQ breaker.

Where It Works Best

The Siemens HB2B090 is intended for use in compatible Siemens HBQ (BQ) bolt-on panelboards serving residential, commercial, and light industrial electrical distribution systems. It is well suited as a replacement for an existing 90 Amp, 2-pole bolt-on circuit breaker with matching electrical ratings and mounting configuration. Before installation, verify that the breaker's amperage, voltage, interrupting capacity, and panel compatibility match the requirements of the existing electrical system.
