LMXD63B500L - 500Amp Circuit Breaker

LMXD63B500L - 500Amp Circuit Breaker

It's a good idea when fitting an LMXD63B500L to check the lug arrangement early on, since this model has load-side lugs even though the given specifications do list the line-side lugs as being included; the figures are important whenever you're replacing equipment that is already in service because amperage by itself doesn't give the full picture.

Key Features and Benefits

• For applications that require a 500-amp breaker setup, the current rating is clearly indicated.
• Three-pole setup. Works with gear made for a three-pole LMXD6 breaker.
• The LMXD6 is a key reference point when verifying the form, fit, and function of existing or obsolete electrical equipment.
• The trip unit is not interchangeable: the trip setting is fixed to the breaker and must be matched when replacing the existing unit.
• The connection arrangement means you no longer have to guess the connection setup, since the load-side lugs are included. However, the specifications do not state that the line-side lugs are included.

Material Compliance and Certifications

No specific UL, CSA, IEC, RoHS, REACH, or other certification or material-compliance information was supplied for the LMXD63B500L.

Where It Works Best

The LMXD63B500L 500A circuit breaker is best suited for existing and older electrical equipment that requires a three-pole Type LMXD6 molded-case circuit breaker fitted with a non-interchangeable trip unit; the line and load-side lugs are particularly useful for matching. However, because the specifications provided do not mention line-side lugs, verify the connection on that side separately when carrying out the installation.
