Bolt On Miniature Circuit Breakers

General Electric Q-line circuit breakers are suitable for protecting electrical circuits and devices from current overloads and short circuits. These units feature a thermal-magnetic tripping mechanism ensuring both instantaneous and time-delayed current limiting functions and a bolt-on mounting configuration for bolting the bus connections of the load centres or lighting panels. Choose from a wide variety of these breakers available in amperage ratings ranging from 15 to 40A on Raptor Supplies.

Square D QOB Series miniature circuit breakers (MCB) safeguard sensitive electrical devices against overloading or short-circuiting. They are ideal for broad-area lighting applications which require lamps with high inrush currents. These bolt-on circuit breakers feature a trip handle mechanism for visual indication of breaker's status and quick-make, quick break action to open all the poles simultaneously when tripped. The breakers are equipped with screw clamp or lug terminals for secure connection and bolt-on mounting for installation in both vertical & horizontal orientations. They are offered in AFCI, GFCI, HIC, PowerLink, shunt trip, high intensity discharge & standard breaker options and are available in current ratings ranging from 10 to 150A on Raptor Supplies.

Square D EGB Series circuit breakers are used in HVAC & electrical systems to protect devices against current overloads and short circuits. They feature a bolt-on connection for reliable attachment between the circuit breaker and the electrical panel or busbar. These circuit breakers have an interrupting capacity rating of 35kAIC at 480V. The lug orientation on these devices allow straight-in wiring through bus bars, eradicating the need to pigtail wires and organise the load centre.

Siemens HGB Series circuit breakers are designed for reducing risks of damages caused by faulty currents and fatal electrical shocks. These units feature a non-interchangeable trip unit with long-time and instantaneous current limiting functionalities and a compact design that saves space and helps reduce the overall panel size. The bolt-on mounting facility with load-side lug terminals of these breakers allow ease-of-installation and a secure wiring configuration. Choose from a wide variety of these Siemens circuit breakers available in current ratings ranging from 15A to 125A on Raptor Supplies.

Siemens MD Series circuit breaker trip units are designed for protecting electrical appliances and are used in conjunction with branch circuit protection while connected with external devices. These Sentron Series trip units feature a thermal-magnetic, non-interchangeable trip overriding mild overloads while instantly reacting to severe current spikes for maximum current limiting protection. They are suitable for use with Siemens MD & HMD molded case circuit breakers for maximum efficiency. These trip units feature a 3 pole design with MD-T type frame for added versatility and are voltage rated at 600V. MD Series trip units are available in current ratings ranging between 500A & 800A on Raptor Supplies.

Siemens QJH Series circuit breakers protect circuits during short circuit & overload conditions and are suitable for reverse feed applications. These UL listed breakers feature a non-interchangeable thermal magnetic trip for providing long-time and instantaneous current limiting protection. They have load side lug terminals for ease of installation & secure wiring configuration, provide current up to 125A and feature a maximum interrupting capacity of 22kA at 240V. QJH Series circuit breakers are available in current ratings ranging between 60A & 225A on Raptor Supplies.
