Integration notes
The breaker ships with two auxiliary switch changeover contacts (H) and one trip alarm switch changeover, plus a nut keeper kit. Mounts in standard IEC switchgear panels; the ETU860M allows field-adjustable LSIG curves, making it suitable for motor control centers where selectivity and ground-fault coordination are required.
