SCHNEIDER QO3-250L12G/SN Main Lug Load Center 250A 25 kA 12 Ways

SCHNEIDER QO3-250L12G/SN Main Lug Load Center 250A (25 kA) 12 Ways
A Main Lug load center means the panel comes without a built-in main breaker, utilizing terminal lugs for direct main incoming cable connection, requiring an external main breaker (MCCB) to control the main power supply for 3-phase 4-wire electrical systems. Designed for surface-mounted installation, it is suitable for systems requiring flexibility in selecting an external main circuit breaker. The panel provides 250A Main Lug terminals and features 12 branch circuit spaces (outgoers), compatible with Schneider Electric QO-type miniature circuit breakers. The panel is durable and safe according to international and Thai standards.
