The LA400LS is physically smaller than the LA400S and has application limitations. The LA4000LS is UL listed only to accept a LAL, 3-Pole circuit breaker. The voltage is limited to 480Vac maximum. The SCCR is limited to 30K rms symmetrical amperes at 480Vac maximum. Copper conductors must be used (aluminum conductors are not acceptable).
