BDA140203 SQUARE D 1P 20A 480V B PH I LINE
The BDA140203 SQUARE D 1P 20A 480V B PH I LINE is a reliable single-pole circuit breaker designed for efficient performance in high-voltage applications. Rated at 20 amps and 480 volts, it ensures optimal protection for your electrical systems. Ideal for use in various commercial and industrial environments, it combines durability with superior functionality.
The BDA-frame is a commercial/industrial-grade breaker rated at 480V with an 18kA interrupting capacity — significantly higher voltage and fault-current ratings than the 120/240V QO or Homeline residential breakers. It is designed for use in commercial panelboards and switchboards, not home loadcentres.
The Square D BDA-frame series is considered a hard-to-find and potentially obsolete product line. Northern Breaker Group specializes in exactly these situations — contact our Calgary, Edmonton, or Vancouver counters or request a quote online and we'll advise on current stock and lead times.
No. While a higher-voltage-rated breaker is not typically used on a lower-voltage system in practice — and may not be compatible with the panelboard bus — the BDA140203 is specifically rated and designed for 480V commercial/industrial applications. Always match the breaker rating to your system voltage and consult a licensed electrician to ensure CEC compliance.
