Square D 989715 Three Phase Molded Case Circuit Breaker

Square D 989715 is a three-phase molded-case circuit breaker (MCCB) rated 15 A at 480 V, configured as a 3-pole device with a 10 kA short-circuit rating. This MCCB protects three-phase feeders in electrical distribution panels, interrupting fault currents quickly to safeguard wiring and connected equipment in industrial or commercial installations operating at up to 480 V. The 989715 designation identifies the exact Square D part, ensuring proper fit, replacement compatibility, and consistent performance within Square D panel systems. With its molded-case construction, the unit is designed for use in panel installations where reliable overcurrent protection for 15 A circuits is required and where space-efficient, modular protection is beneficial. Commonly used to safeguard three-phase distribution feeders in 480 V installations, this model provides the specific current, voltage, and pole-count combination defined by the part number, making it a precise choice for engineers specifying Square D components in new builds or replacements.
