Bolt On Miniature Circuit Breakers

Siemens SHLD Series circuit breakers are designed for protecting electrical equipment against short-circuit and current overload conditions. These UL-listed breakers feature a bolt-on mounting design to ensure ease-of-installation in compact spaces and a thermal-magnetic trip for delivering long-time and instantaneous current limiting functions. Choose from a wide range of these bolt-on circuit breakers, available in 500 and 600A current ratings on Raptor Supplies.

Siemens SHMD Series circuit breakers are designed to protect the sensitive circuits from excessive current flows causing overloads or short circuits. These circuit breakers feature LI (long time and Instantaneous trip) functions for current limiting protection and are equipped with solid state protection mechanisms to electronically control the current flow and to provide an advance safety for appliances. These UL-listed circuit breakers provide a maximum current rating of 800A at an interrupting capacity of 65kA at 480VAC.

Siemens SHND Series circuit breakers are used for providing protection against current overloads and short-circuit conditions in control panels, switchboards and motor control centres. These UL-listed breakers feature a bolt-on mounting design ensuring smooth installation in compact spaces and LI (long time and instantaneous) current limiting function at a maximum interrupt capacity of 65kA at 480VAC.

Siemens SJD Series circuit breakers are designed for reducing risks of damage caused by faulty current supplies and fatal electrical shocks. These devices are calibrated at an ambient temperature of 40 degrees C and feature a bolt-on mounting design which can accommodate aluminium and copper wires of different sizes. They are capable of delivering a maximum current rating of 400A at an interrupt capacity of 35kA at 480VAC.

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 SMD Series circuit breakers are designed for limiting let-through current for protecting downstream components in power distribution applications. These molded case circuit breakers feature a bolt-on design for ease-of-installation & wiring, and solid state components for long-term durability & quick response against faulty currents. Selected models feature short time, instantaneous & long time trip functions for reacting against severe short-circuits at once while avoiding tripping on mild overloads. These 3 pole, 800A circuit breakers are available 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.
