Telergon S5-01253PB0 switch disconnector 3P 125A

The Telergon S5-01253PB0 is a size 0 switch-disconnector from the S5 Series, rated 125 A thermal current at 40 °C in a 3P configuration. The S5 range switches under load up to 1000 V AC and uses a sandwich-type body with self-cleaning, silver-alloy coated blade contacts for a long electromechanical life.
