ETM6E Series loT Molded Case Circuit Breaker(Operated with a fixed handle)
Product Description
This external circuit breaker features remote control functionality and is designed to interface with smart meter signals, enabling automatic tripping upon payment and automatic closing upon payment. Users can choose between active and passive interface modes. The product features a compact design with the motor and circuit breaker integrated into a single unit, making it smaller in size and suitable for various meter boxes.This series of circuit breakers is suitable for 50Hz/60Hz low-voltage power distribution systems with a rated voltage of 415V. The product complies with national standards GB/T 14048.2 and CQC 1148.
Main Features
- The product’s dimensions are suitable for various types of meter boxes and other low-voltage power distribution systems;
- Equipped with a dedicated maintenance lock; when the key is turned to the locked position, the product cannot be closed manually or automatically.
- Provides overload and short-circuit protection
- External handle for manual closing: When the product opens automatically, there is no need to engage the handle when closing manually; simply push it upward to close.
