Product FAQs

6 answers
What system voltages should I check before selecting the Eaton CC3150X?

The voltage ratings are 208Y/120VAC and 240 VAC. The Y indicates a wye system, so check both the system voltage and configuration when selecting this breaker.

What does the three-pole configuration mean for my circuit?

This is a three-pole breaker for a three-phase circuit. Select it when the circuit requires breaker protection across all three phase conductors.

How do the long-time and instantaneous trip functions protect the circuit?

Long-time tripping allows a delay for overload conditions, while instantaneous tripping responds to high fault current without an intentional delay. These functions address overload and short-circuit protection when selecting the breaker.

What conductor sizes and materials can I terminate?

The wire range is AWG 4 to AWG 4/0 for copper or aluminum conductors. Choose conductors within that terminal range, then size them for the circuit load and applicable installation requirements.

Where do the outgoing circuit conductors connect?

The terminal connection is a load-side lug. Terminate the outgoing load conductors there, using copper or aluminum conductors within the AWG 4 to AWG 4/0 range.

How does the 10kAIC rating affect breaker selection?

The 10kAIC interrupting rating at 240V sets the maximum available fault current the breaker can interrupt at that voltage. Select it only where the available fault current at the installation point does not exceed this rating.
