FAQ
How do I read a 3RT2 order number?
The digits after 3RT2 identify the size and current, and the suffix identifies the coil voltage and auxiliary contacts.
What replaces a 3RT1 in this family?
SIRIUS 3RT2 is the newer generation for small and medium frames. Check mounting dimensions before swapping.
