HFXD63B090 - 90Amp Circuit Breaker

HFXD63B090 - 90Amp Circuit Breaker

When an existing electrical system calls for a specific breaker, the details matter. The HFXD63B090 is a 90-amp, 3-pole HFXD6 Sentron frame molded case circuit breaker intended for compatible electrical distribution equipment where its particular form, fit, and electrical ratings are required. If you're replacing a breaker in a legacy or existing system, don't stop at the 90A rating—confirm the frame type, pole configuration, voltage, interrupting capacity, trip-unit design, terminal requirements, and physical dimensions.

Key Features and Benefits

• 90A, 3-Pole Configuration: Provides the amperage and three-pole arrangement required by compatible electrical distribution applications.
• Non-Interchangeable Trip Unit: Uses a fixed trip-unit configuration appropriate to this specific breaker design.
• Suitable for Reverse Feed: Can be used in compatible installations where a reverse-fed breaker configuration is required.
• Load-Side Terminals Included: Supplied with load-side terminals, an important detail to verify when matching an existing installation.
• HACR Rated: Carries an HACR rating for applications where this designation is applicable.
• 50/60Hz Operation: Designed for electrical systems operating at either specified frequency.
