This means the breaker provides short-circuit and magnetic protection only — there is no thermal overload element, so it relies on an upstream or external overload relay for motor running protection. The type code XT4N 160 MA 100 Im=500...1000 3p F F confirms the adjustable instantaneous trip range: 500 to 1000 A (5–10× In), which is the setting range for coordinating with motor inrush. Rated voltage is 690 V AC, covering 400 V and 480 V systems with headroom for 600 V class. The 3-pole configuration is standard for three-phase motor circuits. Frequency rating is 50/60 Hz, suitable for global installations. ## Sizing and coordination for motor branch circuits The 100 A rated current matches motor FLA up to about 100 A, but the magnetic-only trip means the breaker does not carry the overload function — pair it with a separate thermal overload relay or motor protection relay upstream. The adjustable instantaneous trip (Im=500–1000 A) lets you set the magnetic pickup above motor starting current to avoid nuisance trips on inrush, while still clearing a bolted fault. Frame size XT4N supports the 160 A continuous rating of the frame itself, so the breaker can be re-fitted with a higher-rated trip unit later if the motor load changes, without swapping the entire breaker. Dimensions are 8.25 cm wide × 10.5 cm deep × 16 cm high, fitting standard panel layouts for MCCB up to 100 A class.","metaTitle":"ABB 1SDA068118R1 XT4N MCCB, 100 A, Motor Protection","metaDescription":"ABB 1SDA068118R1 XT4N 160 MA 100 MCCB, 3-pole, 100 A rated current, magnetic-only trip unit for motor protection.
