Siemens B290HH Circuit Breaker 90A 2 Pole 120/240V

Product Description

The SIEMENS B290HH is a 2-pole, 90-amp circuit breaker rated for 120/240-volt applications. It is designed to provide overcurrent protection in residential and light commercial electrical panels. This breaker interrupts fault currents and protects branch circuits and feeder circuits from overload and short-circuit conditions. Licensed electricians install this type of device as part of load center upgrades, panel replacements, or new circuit additions. At 0.705 pounds and compact dimensions, it fits standard Siemens and compatible load centers without requiring additional hardware.

The B290HH is suited for residential and light commercial electrical distribution systems where a double-pole, 90-amp breaker is required. Typical applications include large appliance circuits, subpanel feeder protection, HVAC equipment disconnects, and similar 240-volt branch circuits. Its two-pole configuration allows simultaneous interruption of both hot legs in a 120/240-volt system.

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 main service entrance before working inside the panel. Verify bus bar compatibility and available panel space for a 2-pole breaker slot before installation. Do not exceed the breaker's 90-amp rating when sizing the protected circuit conductors.
