BGA161255 SQUARE D 1P 125A 347/600V C PH I LINE

The BGA161255 is a BGA-frame plug-in MCCB intended for Square D commercial and industrial panelboards and switchboards rated for 347/600V systems. It is not compatible with residential loadcentres such as the QO or Homeline series. Contact our team with your panelboard model to verify a proper fit.

A C-curve (also called a Type C or standard inverse time) trip characteristic means the breaker tolerates moderate inrush currents — typically 5–10× rated current — before tripping. This makes the BGA161255 well suited for commercial loads such as lighting circuits, small motors, and mixed branch circuits at 347/600V. If your load has very high inrush (e.g., large motors), a D-curve breaker may be more appropriate. Our specialists can help you select the right trip curve.

Square D's BGA-frame breaker series has been discontinued in some configurations. Northern Breaker Group specialises in obsolete and hard-to-find breakers — we maintain extensive inventory across our Calgary, Edmonton, and Vancouver locations and can source units through our supplier network.
