FXD63B070 - 70Amp Circuit Breaker Description
FXD63B070 - 70Amp Circuit Breaker
The Siemens FXD63B070 is a 70 Amp, 3-pole molded case circuit breaker from the SENTRON FD family, equipped with a non-interchangeable thermal-magnetic trip unit. Rated for 600VAC, this breaker offers an interrupting capacity of 22kAIC at 600VAC and 35kAIC at 480VAC, making it a dependable choice for protecting feeders, distribution equipment, and branch circuits in commercial and industrial electrical systems. If you're replacing an existing Siemens FD frame breaker, matching the original frame, amperage, interrupting rating, and trip characteristics is essential for maintaining proper system operation and compatibility.
