SQUARE D Molded Case Circuit Breakers

Square D MJA Series moulded case circuit breakers are used in commercial facilities, industrial plants, data centres and institutional buildings for reliable protection against overcurrents and short circuits in electrical systems. They have a -pole, 3-phase configuration with bolt-on terminal design for enhanced safety and secure connection. These standard circuit breakers feature an electronic trip for LSI (Long-time, Short-time and Instantaneous) trip functions. They offer current ratings ranging from 300A to 800A. These breaker units are further equipped with line and load side lug terminals to accommodate copper / aluminium wires of sizes ranging from 500 Kcmil to 3 AWG.

Square D PowerPact J Series circuit breakers are used for protecting the circuit from excessive current to prevent fire hazard and equipment damage. These devices allow unit mounting with load- and line-side lugs for easy field installation and maintenance services. They are capable of accommodating aluminium or copper cables with sizes ranging from 350 kcmil to 3/0 AWG and can remain insensitive to mild overloads but provide instantaneous current limiting protection when the wire terminals are exposed to faulty current. These MCCBs feature a handle indicator which provides a visual indication of the three positions (ON, OFF and tripped) of the breaker and can be reset by manually pushing the control lever in the desired position. Choose from a wide range of these IEC protectors available in 3-pole design with a standard voltage rating of 600VAC on Raptor Supplies.

Square D LA Series circuit breakers are primarily designed for automatically opening a circuit under current overloads and short-circuit conditions. These units feature a fixed thermal-magnetic trip, with interrupting ratings of 42kA @ 120VAC, 30kA @ 480VAC and 22kA @ 600 VAC, providing instantaneous and time-delayed functions. The molded case of these C-curve protectors hold the current-carrying components, trip devices and other mechanisms within a very small space. Choose from a wide range of these circuit breakers available in 2- and 3-pole configurations 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.

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 LC Series circuit breakers are designed for installation in commercial and industrial electrical devices for protection against overcurrent and short-circuit conditions. These devices can handle current ratings up to 600A and provide a maximum interrupt capacity of 65kA at 480VAC. They feature I-Line style plug-in design equipped with load-side lug terminals to reduce the wiring and installation downtime, respectively and a thermal-magnetic trip for instantly reacting to severe power surges.
