Product FAQs
8 answersWhat is the difference between Siemens JXD6 and JD6 circuit breakers?
The JXD6 prefix indicates a factory-assembled breaker with a non-interchangeable trip unit. The JD6 prefix indicates a breaker frame designed for interchangeable trip units. Both share the same JD frame footprint and electrical ratings.
What does the L suffix in JXD62B250L indicate?
The L suffix specifies that the breaker comes with factory-installed line and load lugs. This model includes the TA2J6500 lug kit, which accepts 3/0 AWG to 500 kcmil copper or aluminum conductors.
Can the JXD62B250L be reverse fed?
Yes, Siemens JXD6 thermal-magnetic circuit breakers are UL Listed for reverse feed applications.
What equipment is compatible with the JXD62B250L?
This JD frame breaker is designed for installation in Siemens Sentron panelboards, switchboards, and motor control centers.
Is the JXD62B250L suitable for HVAC applications?
Yes, this breaker is HACR rated, making it suitable for heating, air conditioning, and refrigeration equipment branch circuit protection.
How is the trip unit configured on the JXD62B250L?
This breaker features a thermal-magnetic trip unit with fixed thermal protection for overloads and an adjustable magnetic dial for instantaneous short circuit protection. The magnetic trip can be adjusted on the face of the breaker to coordinate with specific load requirements.
Is the JXD62B250L rated for 100 percent continuous load?
No, this is a standard 80 percent rated circuit breaker. Siemens requires an H suffix in the catalog number for 100 percent rated JD frame breakers.
How does this breaker mount into a panel?
The JXD62B250L is a unit mount, feed-thru circuit breaker. It bolts directly to the mounting pan or chassis rather than plugging onto a busbar.
