HQS2100H - 100Amp Circuit Breaker

HQS2100H - 100Amp Circuit Breaker

When you're replacing a breaker in existing equipment, the catalog number is only the beginning. The Siemens HQS2100H is a 100A, two-pole Type HQSH thermal-magnetic circuit breaker rated for 120/240V. Siemens identifies it for electrical distribution and lists it within its Meter Load Center Combo Mains product family. The HQS2100H is built to last, while proper replacement selection still comes down to form, fit, and function. If you're working with a legacy system, compare the complete breaker identification and electrical ratings with the existing unit and equipment documentation before installation.

Key Features and Benefits

• 100A breaker rating: Matches equipment requiring the manufacturer's stated 100-amp configuration.
• Two-pole design: Clearly identifies the pole configuration for comparison with the existing breaker.
• 120/240V rating: Provides the voltage information needed when checking compatibility with electrical distribution equipment.
• Thermal-magnetic trip: Uses the manufacturer-specified trip technology.
• Type HQSH construction: Helps distinguish this breaker from other breaker types that may share similar amperage or voltage ratings.
• Electrical distribution application: Siemens categorizes this breaker for electrical distribution use.
• Meter Load Center Combo Mains family: Provides another useful manufacturer reference when matching the breaker to compatible equipment.
