SIEMENS Molded Case Circuit Breakers

Siemens NEG Series circuit breakers are ideal for switchboards, power distribution panelboards and enclosures for overload protection. They feature a thermal-magnetic, non-interchangeable trip overriding mild overloads while instantly reacting to severe current spikes for maximum current limiting protection. They feature feed-thru connection and load side lug terminals for ease of installation and secure wiring configuration. These circuit breakers have a maximum interrupting capacity of 35kA at 480V and are ideal for reverse feed applications. NEG Series circuit breakers are available in current ratings from 15A to 125A on Raptor Supplies.

Siemens PD Series circuit breakers are designed for reducing fault currents and fatal electrical shocks. These units feature a non-interchangeable trip for long time and instantaneous (LI) functionalities providing maximum current limiting protection. They feature feed-thru connection and load side lug terminals for ease of installation and secure wiring configuration. These PD frame units deliver a maximum interrupting capacity of 100kA at 480V and are suitable for reverse feed applications. PD Series trip units are available in current ratings ranging between 1200 & 1600A on Raptor Supplies.

Siemens HEB Series circuit breakers are designed to protect an electrical circuit from overcurrent occurrences; ideal for use with switchboards, lighting systems and power panels. These devices feature a thermal magnetic trip for providing both instantaneous and long time current limiting protection and a low-tab design with bolt-on mounting facility for ease-of-installation. They are further integrated with load-side lugs to accommodate copper and aluminium wiring arrangements. Choose from a wide range of these HEB Series bolt-on circuit breakers available in amperage ratings ranging from 15 to 125A on Raptor Supplies.

Siemens HND circuit breakers are used to protect the sensitive circuits from excessive current flows causing overloads or short circuits. These devices come with a thermal-magnetic trip mechanism that avoids tripping on mild overloads but instantly responds against severe power surges. They feature line- and load-side lug terminals with feed-thru connection design for ease-of-installation in cramped spaces. Choose from an extensive range of these units available in current ratings ranging from 900 to 1200A, on Raptor Supplies.

Siemens ND Series circuit breakers reduce the risk of fault currents and fatal electrical shocks. These units feature a non-interchangeable trip for long time and instantaneous (LI) functionalities providing maximum current limiting protection. They have load side lug terminals for ease of installation and secure wiring. These ND frame units deliver 50kAIC at 480V and are suitable for reverse feed applications. These ND Series trip units are available in current ratings in the range of 900A - 1200A on Raptor Supplies.
