LL3L600 - 600Amp Circuit Breaker

LL3L600 - 600Amp Circuit Breaker

If LL3L600 is the number you're working from, you've already narrowed things down quite a bit. What we can confirm is straightforward: 600 amps, three poles, Type LL3. The breaker also carries different interrupting ratings depending on system voltage—42 kA at 240VAC, 30 kA at 480VAC, and 22 kA at 600VAC. That's the information worth keeping in front of you when you're identifying a replacement for existing electrical equipment. Same amperage doesn't automatically mean the same breaker. The catalog number, pole count, type, voltage, and A.I.C. all help tell the story.

Key Features and Benefits

• 3-pole configuration
• LL3 type designation
• Clearly defined interrupting ratings for three system voltages
• Useful for existing or legacy equipment where LL3L600 is the specified part number
• Focused on confirmed specifications rather than assumptions from similar LL3 breakers

Where It Works Best

The LL3L600 comes into play when you're servicing existing or legacy electrical equipment and need to match this part number.

Then check the system voltage, because it's tied directly to the interrupting rating. At 240VAC, the supplied A.I.C. is 42 kA. At 480VAC, it's 30 kA. For 600VAC, it's 22 kA.
