B290HH - 90Amp Circuit Breaker

B290HH - 90Amp Circuit Breaker

The Siemens B290HH circuit breaker is designed for electrical systems that require reliable 90-amp protection and a higher interrupting capacity than standard breakers. Built for 120/240VAC applications, this 2-pole Type HBL breaker helps protect your circuits and equipment from overloads and short circuits in commercial and industrial power distribution systems. With a 65kA interrupting rating, the B290HH is commonly used where available fault current levels are higher and additional protection is needed. Its thermal magnetic trip mechanism responds to both overload conditions and sudden faults, helping reduce the risk of damage to electrical equipment and wiring.
