Description

Part of the legacy Q-Frame series, this 100A, two-pole breaker delivers dependable thermal-magnetic protection for systems requiring a 10kAIC rating at 120/240VAC. This plug-on unit mounts into older Square D Q1 load centers and metering equipment. While replaced by the narrower QO2100, this original 3-inch wide frame ensures a precise physical fit in existing enclosures. It features a top-feed configuration for line-side termination and a Visi-Trip indicator for quick fault identification.

Product FAQs

4 answers
What does the "TF" suffix mean on the Q12100TF circuit breaker?

The TF suffix indicates a top-feed configuration. This specific physical layout is required when using the breaker as a main disconnect in older Square D load centers and compatible EZM or UEZM multi-metering equipment.

Is there a modern direct replacement for the Square D Q12100TF?

No. Schneider Electric has designated the Q1-TF breaker line as obsolete without a modern cross-reference. Maintaining legacy panels or metering stacks that require this specific form factor means you must source an original Q1 series replacement.

Can the Q12100TF be installed in a standard QO or Homeline load center?

No. The legacy Q1 frame has distinct physical dimensions and a unique plug-on mounting configuration that prevents it from seating safely in modern QO, QOB, or Homeline panels. It will only fit into enclosures explicitly designed for the Q1 series.

Does the Q12100TF offer equipment ground fault or arc fault protection?

No. This unit features standard thermal-magnetic trip elements for long-time overload and instantaneous short-circuit protection only. It does not provide any integrated ground fault (GFPE/GFCI) or arc fault (AFCI) monitoring.
