Square D Q12100TF 100A 2-Pole 240 V Circuit Breaker

Introducing the Square D Q12100TF 100A 2-Pole 240 V Circuit Breaker — a trusted, two-pole solution designed to protect 240-volt circuits in compatible Square D panels. With a 100-amp rating, this breaker provides robust overcurrent protection for demanding loads while ensuring safe, simultaneous disconnection of both live conductors.

Key specifications

• Current rating: 100 A
• Poles: 2
• Voltage rating: 240 V
• Part number: Q12100TF
• Compatibility: designed to fit compatible Square D panels that accept Q-series breakers

Why this model stands out

The Q12100TF employs a thermal-magnetic trip mechanism, delivering precise response to sustained overloads and sudden short circuits. Its 2-pole design ensures both hot legs trip together, enhancing safety on 240 V circuits and reducing the risk of arcing or equipment damage.

Ideal use cases

• Guarding 240 V branch circuits for equipment like HVAC systems, electric water heaters, and baseboard heating
• Providing reliable protection in residential or light commercial panels that accept Square D Q-series breakers

Installation and compatibility tips

Confirm that your panel accepts Q12100TF and that the circuit load aligns with a 100 A, two-pole configuration. Follow all electrical codes and the panel manufacturer’s installation instructions. When replacing an existing breaker, verify panel compatibility and ensure the overall load calculation supports a 100 A feeder for the intended circuit.

What to expect in daily use

Consistent, dependable protection for 240 V circuits with a straightforward install in compatible Square D panels. The 100 A rating is well-suited for mid-to-high current loads, providing clear, predictable tripping behavior that helps keep wiring and connected devices safe during fault conditions.
