CA2100Y - 100Amp Circuit Breaker

CA2100Y - 100Amp Circuit Breaker

When you're working on an existing electrical system, finding a breaker that matches the original equipment can save time and eliminate unnecessary guesswork. The CA2100Y 100 Amp 2 Pole Circuit Breaker is a Type CA molded case circuit breaker rated for 120/240VAC systems and is often found in commercial and industrial power distribution equipment.

This breaker features a 100-amp rating, a 2-pole configuration, and a 10kA interrupting capacity, making it suitable for many installations that require a compatible Type CA replacement.

Many facilities continue to rely on electrical equipment that has been in service for decades. When a breaker needs to be replaced, matching the correct type, amperage, and configuration is often more important than anything else. The CA2100Y was built with that in mind, giving electricians, maintenance teams, and facility managers a replacement option that aligns with existing equipment requirements.

You'll typically see breakers like this in panelboards, switchboards, distribution equipment, and other systems responsible for delivering power throughout a facility. Rated for operation in ambient temperatures up to 40°C (104°F), the CA2100Y is built to last and remains a dependable part of many established electrical systems.
