Description
ST130 / ST140 Series – Intelligent MCCB Controller
Overview
The ST130 and ST140 intelligent controllers are the core components of smart molded case circuit breakers (MCCB). Suitable for AC 50Hz systems with rated insulation voltage up to 690V and rated operating currents from 32A to 1600A, they protect low-voltage distribution lines and power equipment against overload, short-circuit, and ground fault hazards. They support remote “four-telemetry” functions (remote control, signaling, measurement, and adjustment) via communication interface.
Model Classification
- By frame rating & current: ST130 covers 32A–1600A; ST140 covers 250A–800A
- By poles: 3-pole and 4-pole
- By type: M-type (standard) / H-type (communication)
- By application: Distribution & motor protection / Generator protection (suffix F)
