FAQs

1. What is the difference between frame size (160 A) and In (63 A)?
   • Frame size (Iu) is the maximum current the breaker frame can handle; In is the actual rated current setting of this model (63 A).

2. Can this MCCB be used on DC applications?
   • Yes—up to 500 V DC operational voltage. DC breaking capacity is 18 kA at 250 V DC with two poles in series (per ABB data).

3. Are plug-in or withdrawable versions available?
   • The XT family includes plug-in/withdrawable versions and a wide accessory range. Confirm exact compatibility for this specific code before ordering.
