Square D HGL Series circuit breakers are designed to protect electrical equipment from damages caused by short circuits and overload occurrences. These units come equipped with a thermal-magnetic trip, calibrated at 40 degrees C ( ambient temperature), allowing both instantaneous and long-time current limiting functions. The H-frame design of these breakers offers interrupt capacities of 65kA @ 240 VAC, 35kA @ 480 VAC and 18kA @ 600 VAC. These breakers feature unit mounting (lug-lug) construction for reducing the installation and maintenance downtime and can accommodate aluminium or copper wires with sizes ranging from 14 to 3 AWG. Choose from a wide range of these IEC protectors available in 2 and 3 pole configurations on Raptor Supplies.

Square D HDL Series molded case circuit breakers provide overcurrent or short-circuit protection in industrial & commercial loadcentres and are ideal against severe overloading & mild nuisance tripping. These circuit breakers feature a thermal-magnetic trip for providing both long-time and instantaneous circuit protection and line & load side lug terminals for accommodating aluminium / copper wires & providing a secure connection. They are equipped with a centre placed toggle actuator for manual tripping and fault indication. The free-standing mounting style offers easy and quick installation. HDL Series circuit breakers are available in 2 and 3 pole options on Raptor Supplies.

Square D Q4 Series circuit breakers protect sensitive circuits from excessive current flows causing overloads or short circuits. These circuit breakers feature an over-centre toggle mechanism to provide quick make and break operation with positive handle indication. The thermal-magnetic trip elements are calibrated at an ambient temperature of 40 degrees Celsius to provide uniform tripping. They come with a push-to-trip button that enables the user to manually trip the circuit breaker and perform maintenance checks. Raptor Supplies offers a huge variety of these Q4 Series circuit breakers that can be mounted in any position.

Siemens LD/LXD Series circuit breakers are designed to facilitate both low- and high-interrupting capacity requirements for protecting industrial equipment. These devices feature a thermal magnetic trip unit providing long time and instantaneous current limiting functions against current overloads or short-circuit conditions. They are further integrated with a bolt-on mounting design which can accommodate aluminium and copper wires of different sizes. Choose from a wide range of these bolt-on circuit breakers, available in 2- and 3-pole configurations on Raptor Supplies.

Square D HLA Series PowerPact molded case circuit breakers protect electrical circuits from overcurrents and short-circuits. The current limiting design of these breakers makes them ideal for reverse feed applications. These H frame breakers feature a non-interchangeable, thermal-magnetic trip to provide both long-time & instantaneous trip functions during mild nuisance tripping & severe overloading. They are equipped with I-Line style plug-in for facilitating smooth installation in panelboards. These molded case circuit breakers are available in 2 & 3 pole configurations on Raptor Supplies.

Square D QBA Series circuit breakers are designed for use with panelboards and loadcentres for protecting electrical circuits from short-circuit and current overload conditions. These UL-listed devices feature I-Line style plug-in design for ease-of-installation, load-side lug terminals for hassle-free wiring and a thermal-magnetic trip for providing both time-delayed and instantaneous current limiting functions. Choose from a wide range of these triple-pole circuit breakers available in amperage ratings ranging from 100A to 225A on Raptor Supplies.

Square D LEL Series circuit breakers are specially designed to provide protection against damage from overload and short-circuit conditions.
