LEJ & LEJA Series
Hydraulic-Magnetic Circuit Breakers
INTRODUCTION
The LEJ/LEJA series circuit breaker meets the evolving demand for the high performance protection of critical data center and
telecommunications applications requiring up to 277VAC per pole, UL 489 listing in the smallest case size currently available in the
marketplace. The LEJ/LEJA platform is based on the highly successful and field proven LEG/LEGA designs while incorporating
state-of-the-art arc quenching technologies and offering voltage ratings that are well suited for global applications that require
208VAC through 277VAC ratings for increased power efficiency.
Typical applications include power distribution units (PDUs) used in data center enclosures, telecom AC power supplies and a
variety of Industrial applications benefiting from the higher power density. Like the LEG/LEGA product family, the LEJ/LEJA series
offers a variety of features including different terminations and actuators to meet most any requirements.
