TJD432350 **Older Style** - 350Amp Circuit Breaker

TJD432350 **Older Style** - 350 Amp Circuit Breaker

The TJD432350 Older Style Black Face circuit breaker is a molded case breaker designed for you to use in commercial and industrial electrical distribution systems. With a 350-amp rating and 3-pole configuration, it helps protect against overloads and short circuits in equipment that requires dependable circuit interruption. This breaker is part of the Q-Line series and uses a bolt-on mounting style for a secure fit inside compatible panelboards and distribution equipment. The internal common trip mechanism allows all poles to trip together when needed, helping you protect connected systems during fault conditions. Including load-side lugs can make installation and conductor termination easier during maintenance or replacement work. Built for long service life, this breaker is often used in facilities that rely on maintaining compatibility with existing electrical infrastructure.
