Description
Built for commercial power distribution, this 100-amp molded case breaker incorporates a 120/240V shunt trip for remote actuation. The three-pole design delivers reliable 10kAIC defense while utilizing the Visi-Trip flag for status checks. It mounts securely into aging Square D NQO and Q1 series panelboards. When transitioning to modern hardware, the QO31001021 acts as the designated factory cross-reference. Lug terminals accept 6 to 1/0 AWG wiring for flexible installation.Specifications

Product FAQs
6 answersWhat panelboards accept the Q13100-1021 circuit breaker?
This legacy Q-Frame breaker mounts directly into older Square D Q1 load centers and NQO panelboards, serving as an exact physical fit for aging infrastructure.
What does the -1021 suffix mean on this Square D part number?
The -1021 suffix indicates the breaker is equipped with a factory-installed 120/240V AC shunt trip, which allows the breaker to be tripped remotely by an external voltage signal.
Is there a modern replacement for the legacy Q13100-1021?
Yes, Square D QO series breakers are the current manufacturer-designated substitutes for Q1 breakers. However, installing this original wide-frame Q1 model maintains the exact physical footprint in older NQO enclosures without requiring mounting adapters.
What are the wire gauge requirements for the Q13100-1021 terminals?
The included lugs accommodate 6 AWG to 1/0 AWG copper conductors, or 4 AWG to 1/0 AWG aluminum conductors.
Does the Q13100-1021 feature adjustable trip settings?
No, this breaker utilizes a fixed thermal and fixed magnetic trip unit. It provides standard long-time and instantaneous (LI) protection that cannot be field-adjusted.
Does this breaker include a tripped status indicator?
Yes, it features the classic Square D Visi-Trip indicator, which provides a clear visual confirmation when the breaker has tripped due to an overload or short circuit.
