Delivering reliable circuit protection, the Square D QBL22110 is a 2-pole, 110A MCCB. Belonging to the PowerPact Q-Frame family, it is an excellent choice for commercial environments. This unit-mount breaker is compatible with individual enclosures, switchboards, and panelboards, serving as a cross-reference for the discontinued Q22110. With a 10kAIC rating at 240VAC, it relies on fixed thermal-magnetic trip units (LI) to clear faults and features a visual trip indicator.Specifications

Product FAQs
5 answersWhich Square D enclosures are compatible with the QBL22110 circuit breaker?
The QBL22110 can be installed in Square D Q-Frame circuit breaker enclosures, including catalog numbers Q22200NS for surface mounting and Q22200NRB for NEMA 3R weatherproof applications. These enclosures are designed to house 2-pole QBL, QDL, QGL, and QJL breakers up to 225A.
Can the QBL22110 be used as a main breaker in a Square D NQ panelboard?
Yes, it can be installed as a main breaker in an NQ panelboard by using the NQMB2Q main breaker adapter kit. This kit allows 100A to 225A Q-Frame breakers to be surface mounted as the main disconnect.
What is the difference between Square D QBL, QDL, QGL, and QJL circuit breakers?
These prefixes all represent PowerPacT Q-Frame breakers but indicate different interrupting ratings at 240V. The QBL is rated at 10kA, the QDL at 25kA, the QGL at 65kA, and the QJL at 100kA. They share the same physical dimensions and mounting requirements.
Is the QBL22110 a direct replacement for the discontinued Q22110?
Yes, the QBL22110 serves as the direct cross reference and replacement for the obsolete Square D Q22110 circuit breaker. Both are 2-pole, 110A, 240V breakers with a 10kAIC rating.
What safety precautions should be taken before installing the QBL22110?
Always de-energize the panelboard or enclosure before installing or servicing the breaker. Use a properly rated voltage sensing device to confirm power is off, and wear appropriate personal protective equipment in compliance with NFPA 70E guidelines.
