1 1VCP000048 – Rev. B, en – Presentation – 2010.09 © ABB Group May 1, 2015 | Slide 1 SHS2 Gas insulated switch–disconnector / isolator SHS2 Presentation, Dalmine – Italy - August, 2010

2 SHS2 Main features  SF6-insulated Switch Disconnector - Isolator  Suitable for metal-enclosed secondary distribution switchgear  Stainless steel enclosure  3 positions: LINE - OPEN - EARTH  Earthing switch with making capacity  Separate operation slots for Switch-disconnector and Earthing Switch

3 Characteristics Main Data Rated voltagekV24 Power frequency withstand voltage (50-60 Hz/1 min) (*) kV50 (60) Impulse withstand voltage (*) kVp125 (145) Rated frequencyHz50/60 Rated Normal current (t.a. 40°C) A400/630 Short-time current - 1skA12.5/16/20/25 Making capacitykA31.5/40/50/62.5 Gas absolute pressure (20 °C)kPa125 Distance between phasesmm230 Electrical life (**)Class E3 (line) Class E1 (earth) Mechanical enduranceClass M1 (**) (*) withstand voltage between phase and earth and between phases (withstand voltage between open contacts) (**) According to IEC 60265-1, IEC 60129
