HQS2110H - 110 Amp Circuit Breaker

HQS2110H - 110 Amp Circuit Breaker

Replacing a breaker in existing equipment is much easier when you can compare the important specifications in one place. The HQS2110H is a 110-amp, two-pole Type HQSH thermal-magnetic circuit breaker rated for 120/240 VAC with a 110 kA A.I.C. rating. It is specified for 60 Hz operation and carries an HACR Type 40°C designation. Connection requirements are equally important when you're checking form and fit: the listed wire range is #3–300 kcmil copper or aluminum (CU-AL). The HQS2110H is built to last, but selecting the correct breaker still depends on matching the complete specification.

Key Features and Benefits

• 110A amperage rating: Provides a clear electrical rating for matching compatible equipment that specifically requires a 110-amp breaker.
• Two-pole configuration: Makes pole-count verification straightforward when comparing the HQS2110H with an existing breaker.
• 120/240VAC voltage rating: Clearly identifies the rated operating voltage for compatibility checks.
• Thermal-magnetic operation: Uses the specified thermal-magnetic trip design.
• Type HQSH: Helps narrow the replacement search beyond amperage and voltage alone.
• 60 Hz rating: Specifies the breaker's operating frequency.
• CU-AL conductor compatibility: Listed for a #3–300 kcmil wire range using copper or aluminum conductors.

Material Compliance and Certifications

The supplied specifications identify the HQS2110H as HACR Type and list a 40°C designation. They also specify a #3–300 kcmil CU-AL wire range, indicating the stated conductor compatibility includes both copper and aluminum.

Where It Works Best

The HQS2110H 110A two-pole circuit breaker is appropriate for compatible existing and legacy electrical equipment that calls for a Type HQSH thermal magnetic breaker with a 110A rating, two poles, 120/240VAC rating, 110kA A.I.C. rating, and 60 Hz operation. It is especially important to check the physical footprint and conductor requirements when replacing an existing breaker: this model measures 2.13"W x 7.88"L x 3.00"D and specifies a #3–300 kcmil CU-AL wire range.
