BDA160203 SQUARE D 1P 20A 347/600V B PH I LINE

Yes — the BDA160203 is rated 1-pole, 20A, 347/600V with a 14kA interrupting capacity and a B thermal-magnetic trip curve. These specs make it well-suited for commercial and light industrial branch-circuit protection at both 347V (single-phase lighting) and 600V applications common in Canadian electrical installations.

The Square D BDA series has been discontinued in many configurations and can be difficult to source through standard supply channels. Northern Breaker Group specialises in exactly this type of hard-to-find and obsolete breaker. Contact our Calgary, Edmonton, or Vancouver counter for current availability of the BDA160203.

The 'B' trip curve is a thermal-magnetic characteristic that trips relatively quickly on moderate overloads — typically between 3× and 5× rated current for instantaneous magnetic trip. This makes it appropriate for circuits with resistive or lightly inductive loads such as lighting and general branch circuits. If your application involves motor loads or high inrush equipment, a different trip curve may be more appropriate — our team can help you confirm the right choice.
