BDA140205 SQUARE D 1P 20A 480V C PH I LINE

The BDA140205 is a BDA-frame plug-in breaker rated for 480V commercial and industrial panelboards and switchboards — such as Square D NF and NQOD series I-Line panelboards. It is not designed for residential loadcentres like QO or Homeline. Send us your panelboard model and we'll confirm the fit.

The BDA-frame I-Line series has been largely superseded by newer Square D molded-case lines. The BDA140205 may be difficult to source through standard distribution channels, which is exactly why Northern Breaker Group specializes in hard-to-find and obsolete breakers like this one. Contact us for current availability.

The 18kA interrupting capacity (IC) means this breaker can safely interrupt fault currents up to 18,000 amperes at 480V. You must verify that the available short-circuit current (ASCC) at your panelboard does not exceed 18kA — if it does, a higher-rated breaker is required to meet Canadian Electrical Code (CEC) requirements. Your electrical engineer or utility can confirm the fault current at your distribution point.
