Square D BDA260704 Molded Case Circuit Breaker

This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It uses a plug-on line connection that mounts directly to the I-Line bus interior.

Yes, the PowerPacT B-Frame series is the manufacturer's designated replacement for legacy F-Frame circuit breakers, such as the FA and FH series. It maintains the same 1.5 inch per pole width to fit existing I-Line panelboard spaces without requiring blank fillers.

The line side features a shrouded I-Line plug-on jaw that connects directly to the panelboard bus. The load side uses mechanical lugs that accept 14 AWG to 2/0 AWG aluminum or copper wire.

In Square D I-Line nomenclature, the "4" suffix on a 2-pole breaker indicates a BC phase connection on the panelboard bus.

In Square D PowerPacT nomenclature, the "D" indicates the interrupting rating tier. For this B-Frame breaker, the D-tier provides an 18kA interrupting rating at 480V and 25kA at 240V.

Yes, this thermal magnetic breaker is dual-rated for both AC and DC systems. It supports up to 600V AC and up to 250V DC, providing a 10kA interrupting rating at 250V DC.

No, this breaker features a fixed thermal magnetic trip unit. Both the long-time (overload) and instantaneous (short circuit) trip functions are factory set and cannot be modified in the field.

Yes, PowerPacT B-Frame circuit breakers feature an integral push-to-trip button on the front cover. This allows electricians to manually trip the breaker and verify the mechanical operation of the tripping mechanism.
