HRXD63B180 - 1800Amp Circuit Breaker

HRXD63B180 - 1800Amp Circuit Breaker

Matching a replacement breaker is a detail-driven job, especially when you're working with existing electrical equipment. The Siemens HRXD63B180 is a 1800A, 3-pole SENTRON molded case circuit breaker built around the RD frame and rated for 600V. For anyone sourcing a breaker for compatible legacy equipment, these specifics make it easier to evaluate form, fit, and function without relying on assumptions. The HRXD63B180 is built to last, but proper application still depends on confirming all critical electrical and physical specifications before installation.

Key Features and Benefits

• 1800A current rating: Provides the specified amperage for compatible equipment requiring an 1800-amp RD-frame breaker.
• 3-pole configuration: Gives you a straightforward specification to match against the breaker being replaced and the existing electrical system.
• 600V rating: Rated for 600V operation when used in compatible equipment and within its other specified ratings.
• Thermal-magnetic trip unit: Uses the trip technology identified by Siemens for this SENTRON molded case circuit breaker.
• Non-interchangeable trip: The fixed trip configuration is an important compatibility point when matching an existing breaker.
• No lugs installed: This particular configuration is supplied without installed lugs so that connection requirements can be evaluated separately as part of the equipment match.

Material Compliance and Certifications

According to the supplied Siemens specifications, the HRXD63B180 meets UL 489 and IEC 60947-2 standards. This distinction is worth keeping precise: the supplied product information states that the breaker meets these standards, so no additional listing or certification claim is being inferred.

Where It Works Best

The Siemens HRXD63B180 1800A circuit breaker is appropriate for compatible existing and legacy electrical equipment that calls for its specific combination of RD frame, 1800A rating, three-pole, 600V rating, thermal-magnetic non-interchangeable trip, physical dimensions, and applicable interrupting rating. Because this model comes without lugs installed, connection requirements deserve particular attention when evaluating it as a form, fit, and functional replacement.
