Molded Case Circuit Breaker

General

◆ STM6, STM6LY, STM6RT, STM6E, STM6EL series circuit breakers have a rated insulation voltage up to 1000V, and are suitable for AC 50Hz, rated operating voltage up to 690V, and rated operating current 10A to 800A in power distribution networks.
◆ STM6DC series DC molded case circuit breakers are suitable for DC systems with rated voltage up to 1000V and rated current 10~800A.

Features

◆ Current Limiting Capability: Limits the rise of short-circuit current in the circuit. In circuits protected by STM6 series products, the peak value of the short-circuit current is less than the expected value.
◆ Unique U-shaped stationary contacts enable pre-break technology: Pre-break technology refers to the repulsive electromagnetic forces generated on the U-shaped stationary contacts and the moving contacts when the short-circuit current flows through the contact system.
