HP3B140 - 1400Amp Circuit Breaker

HP3B140 - 1400Amp Circuit Breaker

The HP3B140 is a 1400-amp, 3-pole HP3 molded case circuit breaker intended for electrical distribution applications that require its specific configuration, ratings, and physical dimensions. For maintenance, repair, or replacement work involving compatible legacy electrical equipment, matching the breaker correctly matters—amperage alone doesn't determine compatibility. When your electrical ratings, HP3 type, pole configuration, dimensions, and equipment requirements align, the HP3B140 can provide the form, fit, and function needed for a compatible replacement.

Key Features and Benefits

• 1400A amperage rating for electrical systems designed for a 1400-amp molded case circuit breaker.
• 3-pole configuration for compatible three-phase applications.
• HP3 type makes it easier to identify and match the required breaker configuration.
• 40°C rating gives maintenance professionals another important specification to verify against the existing installation.
• 9.00"W x 15.50"L x 4.75"D dimensions help with physical fit verification before installation.
• Suitable for form, fit, and functional replacement in compatible electrical equipment, including legacy systems where matching the existing breaker specifications is essential.

Material Compliance and Certifications

Specific material compliance, agency certification, or listing information was not provided with the available specifications for the HP3B140. UL, CSA, RoHS, or other certifications therefore should not be assumed from this product description.

If a particular certification, listing, or material-compliance standard is required for the application, verify the markings on the individual breaker and consult the applicable equipment documentation before installation.

Where It Works Best

The HP3B140 1400A 3-pole molded case circuit breaker is best suited to existing electrical distribution equipment that specifically requires an HP3 breaker with matching electrical ratings, dimensions, and configuration. It can be particularly relevant for maintenance and replacement projects involving legacy electrical systems where preserving the original form, fit, and function is a priority.
