The XT2N 160 is the standard 36 kA member of the ABB SACE Tmax XT2 160-frame family. This catalog number pairs the 3-pole fixed body with the MA 160 magnetic-only release: it provides adjustable instantaneous short-circuit protection (960...2240 A) but no thermal overload function, so it is used where overload protection is provided by another device — typically motor feeders with a separate overload relay. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
Q.What is 1SDA076529R1?
It is the ABB catalog number for the SACE Tmax XT2N 160 MA 160 Im=960...2240 fixed 3-pole moulded case circuit breaker with front terminals — a 160 A-frame MCCB with adjustable magnetic-only release and 36 kA ultimate breaking capacity at 415 V AC.
Q.Which release does this breaker use?
The MA 160 magnetic-only release: instantaneous short-circuit pick-up adjustable 6...14×In (960...2240 A). It has no thermal overload function — pair it with a separate overload relay for motor protection.
Q.How does XT2N differ from XT2S/XT2H/XT2L in the same frame?
Same 160-frame footprint, different breaking capacity: XT2N = 36 kA, XT2S = 50 kA, XT2H = 70 kA, XT2L = 120 kA, XT2V = 150 kA at 415 V AC.
Q.How is this unit mounted and connected?
Fixed mounting with front bolt terminals (M6, 6 N·m) accepting busbars 32.5...100 mm². Dimensions are 130 × 90 × 82.5 mm (H × W × D) and net weight approx. 1.4 kg.
