Product FAQs
6 answersWhat does the L suffix indicate in the JD63B225L catalog number?
The L suffix indicates that the circuit breaker is factory-equipped with line and load side lugs. The standard JD63B225 model is typically supplied without lugs.
Which Siemens enclosures are compatible with this breaker?
The JD63B225L is a unit-mount JD-frame breaker designed for installation in Siemens Sentron panelboards, switchboards, and motor control centers.
Is the trip unit on the JD63B225L adjustable?
Yes, it features a thermal-magnetic trip unit with a fixed thermal element and an adjustable magnetic setting for short-circuit protection.
Can the trip unit be swapped out if amperage requirements change?
Yes, the JD63B225L features an interchangeable trip unit design. This allows panel builders to replace the trip unit to match new load requirements without removing the entire breaker frame.
What is the modern replacement for the JD63B225L?
For facility upgrades, this legacy JD-frame breaker is typically replaced by the newer Siemens 3VA series, specifically the 3VA5322-5EC31-0AA0 model. Upgrading to the 3VA series may require a new mounting strap kit depending on your panelboard.
What wire sizes and materials are accepted by the included lugs?
The factory-installed lugs accept both copper and aluminum conductors. They accommodate one or two wires per phase, ranging from 3/0 AWG to 500 kcmil for copper, or 4/0 AWG to 500 kcmil for aluminum.
