Bolt On Miniature Circuit Breakers

Siemens QJ Series circuit breakers are used with branch circuit protection to protect electrical appliances. These UL listed breakers feature a thermal magnetic trip for both instantaneous and long-time overcurrent protection. They provide bolt-on mounting to accommodate aluminium / copper wires and have a QJ type frame. They come in a 3 pole design and operate at a fixed voltage rating of 240V. QJ Series circuit breakers are available in current ratings between 100A & 175A on Raptor Supplies.

Siemens SHJD Series circuit breakers are designed for providing protection against overloads and short-circuit conditions to prevent electrical hazards. These devices feature a thermal-magnetic trip for delivering both long-time and instantaneous current limiting functions and a bolt-on mounting facility for compatibility with panelboards and switchboards. They are further integrated with solid-state protection mechanisms to electronically control the current flow and provide advance safety for sensitive appliances. These UL-listed breakers provide a maximum current rating of 400A at an interrupt capacity of 35kA 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.
