STM 25~100kA Moulded Circuit Breaker , Small High Voltage Protection MCCB

GENERAL

STM1 Moulded case ciecuit breaker is suitable for circuit AC 50HZ/60HZ, rated voltage up to AC 660V,rated operating current to 630A.It features normal structure,reliable performance,compete accessories & high breaking capacity, used foe power distribution and protecting the circuit and electrical equipment against overload and short circuit. It complies with standard of IEC 60947-2 and GB14048.2

Basic Information

Molded case circuit breakers are a type of electrical protection device that is commonly used when load currents exceed the capabilities of miniature circuit breakers. They are also used in applications of any current rating that require adjustable trip settings, which are not available in plug-in circuit breakers and MCBs.
