Square D LA molded case circuit breakers provide basic thermal magnetic protection. Their primary functions are to provide a means to manually open a circuit and automatically open a circuit under overload or short circuit conditions. LA circuit breaker could be used for muliple applications such as construction, in commercial and industrail buildings, for control equipment panels for OEM commercial and even in mines. This 3 poles I-line plug in circuit breaker is equiped with thermal magnetic trip unit with rated current of 125A and voltage of 600VAC. Breaker has an interrapting rating as 22kA at 600VAC, 10kA at 250VDC All LA molded case circuit breakers have trip indication as operating handle being in central position when the breaker is tripped. This circuit breakers are commonly used in I-line combo panel with terminal wire range for AL400LA as 1 wire AWG 1 to 600 kcmil or 2 wires AWG 1 to 250 kcmil aluminium or coopper. LA breakers are UL 489, CSA, IEC certified.
