CA3100 - 100Amp Circuit Breaker

CA3100 - 100Amp Circuit Breaker

Finding the right replacement breaker usually comes down to one thing: matching what's already in the equipment. The CA3100 is a 100 Amp, 3-pole Type CA molded case circuit breaker rated for 240VAC systems and commonly used in commercial and industrial electrical distribution equipment.

This breaker comes with both line-side and load-side lugs installed and features a non-interchangeable trip unit. Those details may seem small, but they're often what determine whether a replacement goes smoothly or turns into a much larger project. When you're working with existing panelboards, switchboards, or distribution equipment, matching the original breaker specifications can save valuable time and help keep maintenance work on schedule.

The CA3100 is frequently found in facilities where electrical systems have been operating reliably for years. Whether you're replacing a breaker that has failed, performing routine maintenance, or stocking spare parts for future service needs, having the correct component on hand makes a difference.
