The Eaton Industries MCCB leakage current relay is an optional accessory for NZM series circuit-breakers. It offers global application options due to flexible and uncomplicated mounting provided by its modular function groups. The relay is approved under IEC/EN 60947-2 standards and suitable for use in three and single-phase systems. It has a voltage range of 200 to 415 V, operates on a pulse current sensitivity following the core-balance principle, and has a fixed delay time set at 10 ms. The relay also provides a warning when current exceeds 30% of its set point via a yellow LED and allows users to install up to two auxiliary contacts. It cannot be used in conjunction with an insulated enclosure, main switch assembly kit, or lower cover.
