HHED63B020 - 20Amp Circuit Breaker

HHED63B020 - 20Amp Circuit Breaker

The Siemens HHED63B020 is a 20-amp, 3-pole molded case circuit breaker from the HHED6 family. It uses an ED frame with a thermal-magnetic trip unit and is rated for applications up to 600VAC. At 600V, the breaker carries an interrupting rating of 18kAIC, while at 480V the Rating is 65kAIC. For maintenance and replacement work, those numbers matter—but so does physical fit. If you're replacing a breaker in existing equipment, matching the complete catalog number is always the safest starting point, followed by the frame, poles, amperage, voltage, interrupting Rating, dimensions, and lug configuration.

Key Features and Benefits
