It's rated 52 A continuous (In) on a 160 A frame (Iu), giving you a compact 3-pole device for motor branch circuits where you want fast short-circuit protection but handle overload separately with an external relay. The adjustable short-circuit trip range of 260…520 A (4–10x In) lets you dial it in without swapping components — handy when the motor inrush data lands somewhere between catalogue values. Rated voltage 690 V at 50/60 Hz covers most industrial supply systems. ## Sizing a coordinated pair Since the MA trip lacks thermal overload, you'll need an external overload relay (e.g., ABB T series or electronic equivalent) wired between the breaker and the motor contactor. The adjustable Im setting lets you match the motor's locked-rotor current without oversizing the protection — useful when you're replacing an existing breaker on a line and want to avoid changing the contactor or cable.","metaTitle":"1SDA068116R1 ABB XT4N 160 MA 52, 52A motor protection breake","metaDescription":"1SDA068116R1 ABB XT4N MPCB, 52 A In, adjustable short-circuit trip 260–520 A, 3-pole, 690 V.
