Product Description
The ABB CB220N is a robust miniature circuit breaker designed for reliable overcurrent and short-circuit protection in residential, commercial, and industrial applications. This 2-pole device, rated at 20 amps, ensures dependable performance with a B-curve trip characteristic, providing instantaneous tripping between 3 and 5 times the rated current. The CB220N offers a breaking capacity of 6kA, effectively interrupting fault currents to prevent damage to equipment and wiring. It features convenient snap-on mounting to standard DIN rails for quick and secure installation. Constructed with high-quality materials, the CB220N guarantees a long service life and consistent operation, contributing to a safe and efficient electrical system.
Is Your Device Showing These Signs?
ABB CB220N circuit breakers commonly exhibit issues such as nuisance tripping caused by incorrect overload settings or faulty thermal-magnetic trip units. Contact wear and degradation due to frequent switching operations or high fault currents reduce breaker lifespan and necessitate replacement. Internal component failures, including damaged arc chutes or operating mechanisms, prevent proper operation and require repair or complete breaker replacement. Routine maintenance, including tightening connections and inspecting for corrosion, prevents premature failure and ensures reliable performance. Improper installation or application outside specified voltage and current ratings leads to immediate failure and poses safety hazards.

Our Repair Process for the
CB220N
Our repair process for ABB CB220N circuit breakers begins with a thorough inspection to diagnose the specific issue, whether it be nuisance tripping, contact degradation, internal component failure, or installation errors. Overload settings are verified and adjusted to the correct specifications, and faulty thermal-magnetic trip units are replaced with new, calibrated units. Worn contacts are refurbished or replaced to restore proper conductivity and reduce the risk of arcing. Damaged arc chutes and operating mechanisms are repaired or replaced to ensure proper interruption and switching functionality. All connections are tightened, and any corrosion is removed to maintain optimal electrical contact. If the breaker is beyond repair or the application is outside specified ratings, a complete breaker replacement is performed to guarantee safety and reliability.
