Three poles, front terminal configuration, with a TMA (thermal-magnetic adjustable) trip unit. ## Integration notes Front terminal design suits panelboard or switchboard bus connections where rear-connect is not an option. TMA trip unit allows field adjustment of the thermal pickup and magnetic instantaneous settings — useful for coordinating with downstream branch breakers on a motor control center or lighting panel schedule.","metaTitle":"ABB XT5HU340ABFF000XXX SACE XT5H 400A 3P MCCB, 65 kA","metaDescription":"ABB SACE XT5H molded case circuit breaker, 400 A, 3-pole, 600 VAC, 65 kA interrupting rating.
