Square D Q1TF - 100A, 240VAC, 2-Pole, Circuit Breaker

Square D Q1TF - 100A, 240VAC, 2-Pole, Circuit Breaker is engineered for reliable, straightforward overcurrent protection in demanding electrical environments. This two-pole unit safeguards two live conductors simultaneously, delivering coordinated disconnection that helps protect wiring, motors, and connected equipment in distribution panels and motor control centers.

Key specifications

• Current rating: 100 A
• Voltage rating: 240 VAC
• Poles: 2-Pole
• Breaker type: Circuit Breaker

Why this 2-pole design matters

The 2-pole configuration is purpose-built for circuits that require simultaneous protection of both hot lines. With the Square D Q1TF, you get synchronized tripping, streamlined wiring, and a compact footprint that simplifies panel layout in busy industrial spaces or OEM configurations. This helps reduce installation time, improves fault response, and supports safer, more predictable electrical operation in today’s distribution systems.

Ideal applications

• Panelboards and switchboards in commercial and industrial facilities
• Control panels for machinery, conveyors, and automated equipment
• OEM equipment where durable, modular overcurrent protection is required
• Motor control centers and feeder circuits that demand reliable protection at 240 VAC

Installation and compatibility

Designed to integrate into standard Square D distribution ecosystems, the Q1TF unit supports flexible installation in panelboards, switchboards, and control panels. For best results, ensure the device is matched to the system’s load requirements and installed according to applicable electrical codes and Square D guidelines. This helps maintain safe operation and consistent protection across your electrical distribution network.

Practical tips and maintenance

• Verify the amperage rating aligns with your load calculations to minimize nuisance trips and install the appropriate protective device for each circuit.
• Keep spare units on hand for rapid replacement in the event of a fault or after a fault condition has been cleared.
• Periodically inspect connections for tightness and signs of wear, especially in high-vibration environments or when equipment experiences frequent switching.
• Always de-energize and follow safety procedures before replacing or servicing the breaker.

With its robust 100 A capacity, 240 VAC operation, and dependable 2-pole design, the Square D Q1TF circuit breaker delivers precise protection for critical electrical systems—from panelboards to motor control centers—so your equipment stays safeguarded and your downtime stays down.
