The development of renewable energy sources on the basis of photovoltaic panels has resulted with the development of switch-disconnectors which are used for switching off DC circuit. Switch-disconnectors series PV with double breaking system completely fulfil requirements for isolation according to IEC 60364-7-712 for photovoltaic installations. PV type of switch-disconnectors can meet all requirements of installation with rated operational voltage up to 1000V (1500V) and operational currents up to 40A in utilization category DC21B. Switch-disconnectors are designed to be placed between photovoltaic cells and DC/AC inverter.

About MTB Fault Indication System MTB, or Mechanical Trip Button is a fault indication system incorporated in advanced protection relaying for electrical power networks. The MTB does not require auxiliary supply to provide a fault indication. The MTB is designed to prevent power circuits from re-energising before a fault is completely rectified. This is an essential safety feature which protection relays using electrical latching mechanisms are not able to provide .

Optional Features • Site Selectable sequences (S1, S2, S3, S4 ) • Pre-pogrammed Custom built operating sequences • Trip & Non-Trip grouping facility for MBAS 0600 • Manned / Unmanned function • Fault Follower contact output per fault Input (NO or NC) rd • Ringback sequence with optional 3 relay output for Ringback hooter, with Trip & Non-Trip grouping facility • Supply fail indication / annunciation • External and / or built-in control push buttons
