Product FAQs
5 answersWhich panelboards are compatible with the 992315 circuit breaker?
This legacy 99 Frame breaker is designed exclusively for bolt-on installation in Square D ML panelboards. It is used to maintain and service older electrical distribution systems that require this specific form factor.
What are the wire gauge requirements for the terminal lugs?
The load-side lugs are rated for dual-rated conductors, accepting 14 to 10 AWG copper wire or 12 to 10 AWG aluminum wire. Ensure proper torque specifications are followed during installation.
Does this breaker offer adjustable trip settings?
No. The 992315 utilizes fixed thermal and fixed magnetic trip elements. It provides standard long-time overload and instantaneous short-circuit (LI) protection without field adjustability.
Is the 992315 part of a current production series?
No, it is part of the legacy 99 Series from Square D. It serves as a direct replacement component for existing commercial and industrial ML panelboard setups rather than for new construction.
What must be verified regarding the 10kAIC rating before installation?
You must confirm that the available fault current at the ML panelboard does not exceed 10,000 amps at 240V AC. Installing this breaker in a system with a higher fault current violates safety standards and equipment ratings.
