Description
Designed for heavy-duty industrial environments, the Siemens CF3B040 is a 3-pole, 40A current-limiting circuit breaker. It bolts into older Siemens switchboards and motor control centers, providing a seamless replacement solution. For modern upgrades, this unit crosses over to the CED63B040. Delivering a massive 200kAIC rating at 480VAC, it combines fixed thermal-magnetic protection with integral Amp-Trap fuses to drastically reduce let-through energy during severe short circuits.
