Description
Selective Residual Current Circuit Breakers with Overload protection (RCBO) AD12MS are used to build selective (multistage) differential current protection circuits. Meant for operation in single-phase electrical circuits alternating-current voltage 230 V frequency 50 Hz, rated on currents from 20 A to 63 A. Rated breaking residual current (tripping setting) 100 mA and 300 mA. Used in switchboards of residential and public buildings, apartment panels, devices for temporary power supply of construction sites, garden houses, garages. The improved construction of the differential unit and compact case help to save space in the shield.
Advantages
- Copser tinned bus used in TTI-A transformers gives opportunity of connecting both copper and aluminum conductors.
- Each transformer set includes a cover shielding the secondary terminals ensuring exploitation safety.
- Inspection occurrence is established by means of a verification mark impression on the TTI casing and in the passport.
- Weight and dimensions are by 10-20% smaller than that of comparable transformers of other domestic manufacturers.
- Average service life – 25 years.
