HRD63B160 - 1600Amp Circuit Breaker

HRD63B160 - 1600Amp Circuit Breaker

When you're matching a large-frame breaker for existing equipment, small specification differences can become big problems. The Siemens HRD63B160 is a 1600-amp, 3-pole SENTRON molded case circuit breaker built around the RD frame and a thermal-magnetic trip unit. It carries a 600V rating, with an interrupt rating of 50 kAIC at 600V and 65 kAIC at 480V.

Key Features and Benefits

• 1600A rating: Clearly identifies the continuous current rating to match the existing breaker and equipment requirements.
• Three-pole configuration: Provides the specified 3-pole arrangement for compatible electrical equipment.
• 600V rating: Suitable for equipment specifically designed around the breaker's stated voltage and other electrical ratings.
• RD frame: An important form-and-fit detail when identifying a functional replacement in compatible equipment.
• Thermal-magnetic trip unit: Matches the trip technology specified by Siemens for the HRD63B160.
• Line- and load-side lugs included: Uses TC5R600 lugs, eliminating guesswork about the manufacturer-specified lug designation.

Material Compliance and Certifications

Siemens states that the HRD63B160 meets UL 489 and IEC 60947-2 standards. Those are the specific standards identified in the supplied manufacturer information, so no additional certification or listing claims should be assumed without further documentation.

Where It Works Best

The Siemens HRD63B160 makes sense when maintaining compatible existing or legacy electrical equipment that specifically calls for a 1600A, 3-pole RD-frame molded case circuit breaker with the corresponding voltage, interrupt, trip, and connection requirements. It's especially important not to select this breaker on amperage alone. The RD frame, physical dimensions, 600V rating, interrupt rating at the applicable system voltage, thermal-magnetic trip unit, and lug configuration must all match the installation requirements.
