HLMXD63B700 - 700Amp Circuit Breaker

HLMXD63B700 - 700Amp Circuit Breaker

When you're replacing a circuit breaker in existing equipment, the details matter. The Siemens HLMXD63B700 is a 700A, 3-pole molded case circuit breaker from the SENTRON line, built around the LMD frame and rated for applications up to 600 VAC. It uses a fixed, non-interchangeable thermal-magnetic trip unit with a standard 40°C rating. Interrupting capacity is 50 kAIC at 600V and 65 kAIC at 480V. Just as important for replacement work, this particular configuration is supplied without lugs installed. The breaker measures 7.5 inches wide, 16 inches high, and 4.5 inches deep, allowing installers to compare its electrical and physical specifications with the equipment already in place. The HLMXD63B700 also meets UL 489 and IEC 60947-2 standards.

Key Features and Benefits

• 700A, 3-pole configuration: Matches applications designed for a 700-amp, three-pole molded case circuit breaker.
• 600 VAC rating: Suitable for compatible systems that require this voltage.
• Thermal-magnetic protection: Uses a fixed, non-replaceable thermal-magnetic trip unit.
• LMD frame: Designed around the physical form and fit of the specified LMD breaker frame.
• No lugs installed: An important detail when matching the HLMXD63B700 to an existing installation.
• Standard 40°C breaker rating: Provides a clear specification for application and replacement checks.
• Recognized standards: Meets UL 489 and IEC 60947-2 requirements.

Where It Works Best

The HLMXD63B700 makes the most sense when you're working with existing commercial manufacturers' electrical equipment that calls for its particular combination of 700 amps, three poles, 600 VAC, an LMD frame, and a fixed thermal-magnetic trip unit. That makes it especially relevant for maintenance and replacement projects where the goal is to match the original breaker's form, fit, and function.
