SQUARE D Molded Case Circuit Breakers

Square D MXL Series circuit breakers are used to safeguard power distribution systems, equipment and critical machinery from overcurrents and short circuits. They are used in commercial, industrial and institutional facilities where electrical protection is paramount. These MXL Series circuit breakers have a solid-state protection mechanism that provides precise and responsive protection against electrical faults and increased stability. Whether dealing with overcurrents, short circuits, or other potential hazards, the solid-state protection of these circuit breakers plays a crucial role in preventing damage and ensuring the uninterrupted operation of electrical systems. They incorporate LSI (long-time, short-time and Instantaneous) functions allowing for accurate and adjustable protection based on the specific characteristics of the connected load. These circuit breakers have a three-pole configuration safeguarding each phase against potential faults, thus enhancing the efficiency of the protection.

Square D HDP Series circuit breakers are designed for protecting downstream components from severe inrush currents. They feature a thermal magnetic trip unit that allows both instantaneous and time-delayed functions for maximum overcurrent protection. These 3-pole design circuit breakers have a unique I-line design with lugs load and nut line terminals, providing easy installation and hassle-free wiring configuration. They can accommodate copper or aluminium wires with sizes ranging from 14 - 3/0 AWG, for flexibility, strength and safety. These UL-listed breakers offer bolt-on mounting for installation in both vertical and horizontal positions.
