ОПИСАНИЕ ПРОДУКТА
SCHNEIDER ELECTRIC LV426941 - Compact NSXm Molded Case Circuit Breaker (MCCB)
The SCHNEIDER ELECTRIC LV426941 is a Compact NSXm series molded case circuit breaker (MCCB) designed for electrical circuit protection within low-voltage industrial and commercial power distribution systems. This device incorporates a thermal-magnetic trip unit, providing both overload and instantaneous short-circuit protection. It is engineered for fixed panel mounting, suitable for applications requiring precise current interruption and a 50kA breaking capacity, such as main and sub-distribution boards, motor control centers, and machinery protection.
