Bolt On Miniature Circuit Breakers

Siemens bolt on circuit breakers protect electrical circuits & connected equipment against short circuits & flow of high magnitude currents for manufacturing facilities, processing plants & power distribution applications. These solid state breakers are ideal for reverse feed operations and feature long time & instantaneous trip functions for reacting against severe short-circuits at once while avoiding tripping on mild overloads. They come with load & line side lug terminals for ease-of-wiring while eliminating loose connections. SLD frame molded case circuit breakers are available in 500 & 600A current ratings on Raptor Supplies.

Siemens FD Series circuit breakers are ideal for industrial switchboards, as well as lighting & control panels for protection against current surges & overloads. These UL-listed circuit breakers feature thermal magnetic trip for long time and instantaneous trip functions during severe short circuit conditions while avoiding nuisance tripping in mild fluctuations. They come equipped with line & load lug terminals ensuring hassle-free wiring arrangement and provide support against extreme vibration. Sentron Series circuit breakers are available in current ratings ranging from 70 to 250A on Raptor Supplies.

Siemens ND Series interrupt the current flow and protect downstream components from severe overload and short circuit conditions. These Sentron Series trip units feature a thermal magnetic trip for providing both instantaneous and long time current limiting protection. They are suitable for use with Siemens ND & HND molded case circuit breakers for maximum efficiency. These trip units feature a 3 pole design with ND-T type frame for added versatility and are voltage rated at 600V. ND Series trip units are available in 1000A & 1200A current ratings on Raptor Supplies.

Siemens BQD Series circuit breakers protect industrial machinery from short-circuit and overload occurrences. These UL-listed circuit breakers feature a thermal-magnetic, non-interchangeable trip overriding mild overloads while instantly reacting to severe current spikes for maximum current limiting protection. They have bolt-on mounting design which can accommodate aluminium & copper wires and are available in current ratings between 25A & 100A on Raptor Supplies.

Siemens NEB Series circuit breakers protect against overloads and short circuits to prevent electrical hazards. They feature a non-interchangeable, thermal-magnetic trip which overrides mild overloads and instantly reacts to faulty conditions. They come equipped with bolt-on mounting facility and load side lug terminals for ease of installation and secure wiring configuration. NEB Series circuit breakers are available in 1, 2 & 3 pole configurations on Raptor Supplies.
