HQS2175H - 175Amp Circuit Breaker

HQS2175H - 175Amp Circuit Breaker

When you're replacing a breaker in existing equipment, 175 amps is only the beginning of the match. The Siemens HQS2175H is a two-pole, Type HQSH thermal-magnetic circuit breaker rated at 120/240V, with a 100kA interrupt rating and plug-in connection. Those details help narrow things down quickly when you're working with compatible electrical distribution equipment or maintaining a legacy system.

Key Features and Benefits

• 175A rating: One of the first numbers to check when matching an existing breaker.
• Two-pole design: Provides the required pole configuration for equipment calling for this specific setup.
• 120/240V rating: Clearly defined so you can compare it with the electrical requirements of the existing installation.
• Type HQSH: Helps identify the breaker configuration when replacing an existing HQSH unit.
• Thermal-magnetic trip: Matches the manufacturer-specified trip range for the HQS2175H.
• Plug-in connection: Provides another practical checkpoint for confirming compatibility.
• Electrical distribution application: Manufacturer information includes compatible load center main and feeder use.

Where It Works Best

The Siemens HQS2175H makes sense for compatible existing and legacy electrical distribution equipment that specifically requires its combination of 175A, two poles, 120/240V, 100kA interrupt rating, Type HQSH configuration, thermal-magnetic trip, and plug-in connection. The manufacturer also identifies compatible load center main and feeder applications.
