QS2110HH - 110 Amp Circuit Breaker

QS2110HH - 110 Amp Circuit Breaker

When your electrical system needs a 110-amp breaker with high interrupting capacity, the Siemens QS2110HH circuit breaker delivers the protection ratings you need. This 2-pole, Type HQS thermal-magnetic circuit breaker is rated for 120/240V AC applications and offers an impressive 65,000-amp (65kA) interrupting capacity. Designed for use in compatible electrical distribution equipment, the QS2110HH helps protect circuits against overloads and short circuits while meeting the requirements of installations where a higher available fault current must be considered.

Key Features and Benefits

• 110-Amp Current Rating: Provides overcurrent protection for electrical circuits designed to use a 110A breaker.
• 2-Pole Configuration: Designed for compatible two-pole applications in 120/240V AC electrical systems.
• Thermal-Magnetic Trip Mechanism: Combines overload protection and short-circuit protection in one circuit breaker.
• Type HQS Design: Provides a specific breaker configuration for matching approved electrical equipment and replacement requirements.
• HACR Designation: Identified for heating, air-conditioning, and refrigeration applications where permitted by the equipment specifications.
