Square D BDA260304 Molded Case Circuit Breaker

This breaker is designed for use in Square D I-Line panelboards and switchboards. It features an I-Line style plug-on connection that mounts directly to the busbar stack, eliminating the need for cabled bus connections.

The factory-installed lugs accept 14 AWG to 2/0 AWG aluminum or copper conductors. Always torque the terminals to the specifications printed on the breaker faceplate to ensure a secure connection.

Yes, this thermal-magnetic breaker is rated for DC applications, providing up to 10kA interrupting capacity at 250VDC.

In the Square D PowerPacT B-frame nomenclature, the D indicates the interrupting rating class. It signifies a maximum interrupting capacity of 18kA at 480VAC.

Yes, like all PowerPacT B-frame circuit breakers, it is equipped with dual-break rotating contacts. This design rapidly limits short-circuit currents and reduces peak let-through energy to enhance equipment protection.

It features a fixed thermal-magnetic trip unit with Long-Time (L) and Instantaneous (I) protection functions. The thermal and magnetic trip thresholds are factory-set and non-adjustable.

The breaker features plug-on jaws that engage directly with the I-Line busbar stack. It is then secured to the panelboard backpan using the integrated mounting bracket, allowing for rapid installation without individual wire connections to the bus.

The BDA260304 is a direct replacement for the discontinued FA26030BC circuit breaker. Both are 30A, 2-pole breakers with a BC phase connection designed for I-Line panelboards.

This specific catalog number is factory-configured with a BC phase connection for installation in Square D I-Line panelboards. This allows panel builders to properly balance loads across the bus.
