Material Compliance and Certifications
The LD63B250 is specified as meeting UL 489 and IEC 60947-2 standards.
The manufacturer also provides information related to REACH Article 33 and references WEEE (2012/19/EU) take-back obligations. The supplied manufacturer data did not include RoHS compliance information, and it did not include a SCIP number.
Where It Works Best
The LD63B250 is a good fit for compatible existing and legacy electrical equipment that requires a 250A, 3-pole LD frame breaker with the ratings and connection arrangement listed here.
Start with the system voltage and available fault current. The breaker is rated 25kA at 600V and 35kA at 480V, so the interrupting rating must meet the installation requirements.
