Explanation:
The RTS type outdoor on load circuit breakers (isolating switches) included in this list are used to switch between short and ring main lines or transformers (which can be equipped with medium voltage HRC fuses for short-circuit protection), or to switch under load conditions
The RTS type switch complies with IEC/IEEE and DVE recommended standards. Specially compliant with DIN VDE 1671 Part 3 and IEC publications IEC-61265, IEC-129.
Features:
Compact design
All steel parts, stainless steel or hot-dip galvanized
A sturdy and stable base frame
Main contact points for anti icing
There are two types of insulators: ceramic or silicone resin.
Due to the presence of two fixed terminals, the sag of the circuit connection is minimized
Complete maintenance of rust proof aluminum alloy - arc chamber
Closing program without external arc
Under specific conditions, there may be short-circuit connection capability
Easy to install and set up on site
High reliability: up to 1? 11 cycles (depending on the current applied)
All conductive components are silver plated, nickel plated, or tin plated
Almost maintenance free
