It is part of the legacy Westinghouse J-Frame family, specifically the AB De-Ion series. It shares the same physical footprint as other classic J-Frame breakers, allowing for direct bolt-on replacement in existing setups.
How is the trip unit configured on the JA3225?
It utilizes a thermal-magnetic trip unit featuring a fixed thermal element for long-time overload protection and an adjustable magnetic element, allowing electricians to fine-tune the instantaneous short-circuit response.
What wire sizes are accepted by the terminals on this breaker?
The standard mechanical lugs on the JA3225 accept aluminum or copper conductors ranging from 4 AWG to 350 kcmil. Ensure proper torque specifications are followed during installation.
How does the JA3225 connect to the panel bus?
It features a bolt-on mounting configuration. The breaker bolts directly to the panelboard bus, providing a secure, high-amperage connection suitable for demanding commercial and industrial environments.
