HQS2150H - 150Amp Circuit Breaker

HQS2150H - 150Amp Circuit Breaker

Need to replace an HQS2150H in existing electrical equipment? The label is a good place to start, but amperage alone doesn't tell the whole story. The Siemens HQS2150H is a 150-amp, two-pole Type HQSH circuit breaker rated for 120/240V, with a 100kA interrupt rating and thermal-magnetic trip. When you're working with existing or legacy equipment, the important thing is getting the complete match right: breaker type, amperage, pole count, voltage, interrupt rating, trip design, and physical fit all matter.

Key Features and Benefits

• 150A rating: Provides a clear amperage specification for matching the breaker to compatible equipment.
• Two-pole configuration: Makes pole-count verification straightforward when comparing against an existing breaker.
• 120/240V rating: Matches electrical equipment specifically requiring this voltage configuration.
• Thermal-magnetic trip: Uses the manufacturer-specified trip design for the HQS2150H.
• Type HQSH: An important breaker-family designation when confirming compatibility with existing equipment.
• Electrical distribution use: Manufacturer information identifies applications including compatible load center mains and feeders.

Where It Works Best

The HQS2150H makes sense for compatible existing and legacy electrical distribution equipment that calls for a 150A, two-pole Type HQSH thermal-magnetic circuit breaker with a 120/240V rating and 100kA interrupt rating. Manufacturer information specifically associates this breaker with compatible load center main and feeder applications.
