Product FAQs
6 answersWhen should I choose the Eaton BKG3M400 main breaker kit?
Choose this main breaker kit when the electrical design calls for a breaker serving the main circuit. A main breaker provides overcurrent protection for that circuit rather than an individual branch circuit.
How does the 480V rating guide selection?
The rated voltage is 480V. Check the circuit's operating voltage against this rating when selecting the breaker kit.
How do I use the 65kAIC interrupting rating?
The 65kAIC interrupting rating describes the breaker's ability to interrupt fault current. The available fault current at the installation point must not exceed this rating.
Which phase configurations should I consider when selecting this kit?
The phase rating covers 1-phase and 3-phase applications. Match the phase configuration to the electrical system as part of breaker selection.
What dimensions should I use for installation layout planning?
The kit measures 5 in high, 22 in long and 9 in wide. Use these dimensions to plan installation space and the physical layout.
How do the UL and NEMA approvals guide selection?
The kit has UL and NEMA approvals. Use these approvals when checking the product against project requirements that call for UL and NEMA approval.
