SQUARE D Molded Case Circuit Breakers

Square D QDL Series circuit breakers come in a PowerPact Q frame for overcurrent protection and switching On AC systems. These circuit breakers feature an over-centre toggle mechanism with a trip-free action for quick make and break operation. The integral push-to-trip button in the cover enables the user to manually trip the breaker. These breakers are built in accordance with UL Standard 489 and NEMA Standard AB-1-1999. They feature a thermal-magnetic trip mechanism that overrides mild current while instantly responding to heavy fluctuations. Raptor Supplies offers a huge variety of these circuit breakers in 2 and 3 pole configurations.

Square D PGA Series circuit breakers are designed for installation in panelboards and loadcentres for protecting electrical circuits against short-circuit conditions and current overloads. These UL-listed & CSA-certified breakers feature I-Line style plug-in design for ease-of-installation and an electronic trip for short-time, long-time and instantaneous current limiting functions. They are available in maximum current rating and interrupting capacity of 1200A and 65kA at 480VAC, respectively on Raptor Supplies.

Square D LE Series circuit breakers are designed to interrupt circuits exceeding the ambient operating temperature. These devices feature an electronic trip unit comprising current sensors, a Micrologic processor and a trip mechanism providing instantaneous, short-time and long-time current limiting functions. They are further integrated with I-Line style plug-in design and load-side lugs for reducing the installation and wiring downtime, respectively. Choose from a broad range of these current limiting breakers available in amperage ratings ranging from 250 to 600A on Raptor Supplies.

Square D LEL Series circuit breakers are specially designed to provide protection against damage from overload and short-circuit conditions. These UL-listed devices feature a bolt-on mounting design to ensure ease-of-installation in compact spaces and provide current ratings up to 600A at a maximum interrupt capacity of 65kA at 480VAC. They are integrated with a unique MicroLogic non-interchangeable trip for delivering long-time, short-time and instantaneous current limiting functions.

Square D LH Series circuit breakers are best suited for use in panelboards, industrial enclosures, busway plug-in units, switchboards and motor control centres for protection against short-circuit conditions and current overloads. These CSA-certified devices feature a thermal magnetic trip for providing instant reaction against severe power surges while avoiding tripping on mild overloads. They are integrated with I-Line style plug-in design for ensuring ease-of-installation and load-side lugs for hassle-free wiring. Choose from a broad range of these current limiting breakers available in amperage ratings ranging from 125 to 300A on Raptor Supplies.

Square D LI Series circuit breakers are compatible for use with panelboards and loadcentres to protect sensitive electrical circuits against short-circuit conditions and current overloads. These UL-listed devices feature I-Line style plug-in design for ease-of-installation, load-side lug terminals to reduce the wiring downtime and a thermal-magnetic trip unit to provide both long-time and instantaneous current limiting functions. Choose from a wide range of these triple-pole circuit breakers available in amperage ratings ranging from 400 to 600A on Raptor Supplies.

Square D LIL Series molded case circuit breakers safeguard electrical circuits by quickly interrupting the current's flow in the event of overloads or short circuits, preventing damage to equipment and ensuring safety. These breakers utilise their advantage in commercial and industrial environments for reliable circuit protection. They feature a feed-thru design that enables power to pass through the breaker uninterrupted. They operate at voltages up to 600V and have interrupting capacity of 200kAIC at 480V without causing damage. These circuit breakers have a three-pole configuration for managing circuits across three phases, ensuring comprehensive protection.
