HRXD63B160 - 1600 Amp Circuit Breaker

HRXD63B160 - 1600 Amp Circuit Breaker

When you're matching a breaker for an existing RD-frame installation, the catalog number is only the beginning. The Siemens HRXD63B160 is a 1600A, 3-pole SENTRON molded case circuit breaker rated for 600V, with a thermal-magnetic, non-interchangeable trip unit. Siemens specifies that the HRXD63B160 meets UL 489 and IEC 60947-2 standards and identifies it as a standard 40°C RD-frame breaker.

Key Features and Benefits

• 1600A current rating: Provides a clear match point for equipment requiring a 1600-amp breaker with the remaining HRXD63B160 specifications.
• 3-pole configuration: Designed with three poles, an essential detail when matching an existing breaker arrangement.
• 600V rating: Matches electrical equipment requiring this voltage rating and a compatible breaker type.
• Thermal-magnetic trip unit: Uses the trip technology specified by Siemens for this SENTRON molded case circuit breaker.
• Non-interchangeable trip: The trip unit is specifically identified as non-interchangeable, an important point when evaluating replacement compatibility.
• RD-frame construction: Gives technicians another specific identifier to compare against the existing breaker and equipment documentation.

Material Compliance and Certifications

Siemens states that the HRXD63B160 meets UL 489 and IEC 60947-2 standards. That wording is kept intentionally precise; the supplied manufacturer information does not provide a separate UL listing or certification statement, other than stating that the breaker meets these standards.

Where It Works Best

The Siemens HRXD63B160 makes sense for maintaining compatible existing or legacy equipment that specifically calls for a 1600A, 3-pole RD-frame molded-case circuit breaker with a thermal-magnetic, non-interchangeable trip unit. Its 600V rating, interrupt ratings, frame, physical dimensions, and no-lugs configuration provide meaningful details for comparison with the breaker being replaced.
