Siemens qs2100hh 100A 120/240V 2-pole Circuit Breaker

Product Description

The SIEMENS qs2100hh is a Type HQS low-voltage molded case circuit breaker rated for 100 amps at 120/240 volts AC. It provides thermal/magnetic trip protection and delivers a 65 kA interrupt capacity, making it suited for demanding residential and light commercial panel applications. The plug-in connection type simplifies installation in compatible load centers. Electrical contractors and licensed electricians install this breaker as a primary overcurrent protective device within distribution panels and sub-panels. At 9 inches long, 6 inches wide, and 3 inches tall, it fits standard enclosures designed for this form factor.

This circuit breaker is designed for single-phase, 2-pole applications operating at 120/240 VAC. It is typically installed in residential main panels and light commercial distribution equipment where high interrupt ratings are required. The 65 kA interrupt capacity addresses installations with elevated available fault current, such as service entrances or panels fed from larger transformers. Electricians specify this breaker when the load requires 100-amp double-pole protection with reliable thermal and magnetic trip response.

Key Features

• 100-amp continuous current rating for 2-pole, single-phase loads
• 65 kA interrupt capacity for high available fault current installations
• Thermal/magnetic trip mechanism provides overload and short-circuit protection
• Plug-in connection type for compatible Siemens load center installations
• 120/240 VAC rated for standard North American single-phase distribution
• Molded case construction — Type HQS — provides durable arc isolation

Compatibility

Designed as an OEM-style replacement or direct-fit breaker for load centers and distribution panels that accept Type HQS plug-in molded case circuit breakers.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the panel before handling any breaker or bus connection. Verify the load center bus accepts the plug-in Type HQS footprint before installation. Do not exceed the breaker's rated voltage, amperage, or interrupt capacity for the intended circuit.
