FXD63B090L - 90Amp Circuit Breaker Description
FXD63B090L - 90Amp Circuit Breaker
The Siemens FXD63B090L is a 90 Amp, 3-pole molded case circuit breaker from the SENTRON FD family, featuring a fixed thermal-magnetic trip unit for dependable protection against both overloads and short circuits. Rated for systems up to 600VAC, it carries an interrupting capacity of 22kAIC at 600VAC and 35kAIC at 480VAC. Those numbers aren't just part of the specification sheet—they're critical when matching a replacement breaker to the available fault current in your existing electrical system.
