HQS2125H - 125Amp Circuit Breaker

HQS2125H - 125Amp Circuit Breaker

When you're replacing a breaker in existing electrical equipment, the catalog number is only the starting point—the electrical ratings and breaker configuration must also match. The Siemens HQS2125H is a 125-amp, two-pole Type HQSH thermal magnetic circuit breaker rated for 120/240V electrical distribution applications. Its manufacturer-listed 100kA interrupt rating is an important specification to verify against the requirements of the equipment and electrical system.

Key Features and Benefits

• 125-amp rating: Clearly defined amperage makes it easier to compare the HQS2125H with the breaker and equipment specifications already in place.
• Two-pole configuration: Provides the specified 2-pole arrangement for compatible electrical distribution equipment.
• 120/240V rating: Manufacturer-rated for 120/240V applications where this breaker configuration is required.
• Thermal magnetic trip: Uses the manufacturer's specified thermal magnetic trip design.
• Type HQSH construction: The HQSH designation helps identify the correct breaker family when matching an existing installation.
• Electrical distribution application: Manufacturer information identifies this breaker for electrical distribution use.

Material Compliance and Certifications

Manufacturer specifications identify UL 489 as the standard associated with the HQS2125H. The supplied environmental data indicate that RoHS substance-restriction compliance information and a SCIP number are unavailable. REACH Article 33 information is referenced by the manufacturer, but the supplied data does not provide a specific compliance declaration. The product is also listed as having no WEEE take-back obligation under the referenced WEEE requirements.

Where It Works Best

The Siemens HQS2125H 125A two-pole circuit breaker makes sense for compatible existing and legacy electrical distribution equipment that specifically calls for a Type HQSH breaker with a 125A rating, two poles, 120/240V operation, thermal-magnetic trip, and a 100kA interrupt rating. Manufacturer information places this breaker within its load center mains, feeders, and miniature circuit breaker offering.
