Abb Circuit Breaker 4P 50A 36KA 4 Modules S120471

A circuit breaker is a safety device that can automatically (i.e., without external intervention) interrupt the flow of electric current in an electrical circuit in the event of an overcurrent.

The C curve, trip threshold of 5 to 10 times In, for application of ohmic-inductive circuits with medium inrush currents. And widely used in domestic systems.

AC-type differ ential circuitbreaker tripping is assured for suddenly or slowly increasing applied sine-sine differential alternating currents (IEC EN 61008-1).

System pro M compact S800 high-performance circuitbreakers protect installations from overloads and short circuits, ensuring reliability and safe operation. They are available in different characteristics (B, C, D, K, and magnetic only), configurations (1P, 2P, 3P, 4P), breaking capacity (up to 50 kA at 230/400 VAC ) and current ratings (up to 125 A). All thermal-magnetic circuit breakers in the S800 range comply with CEI-EN 60898-1, CEI- EN 60947-2 standards, allowing use in commercial and industrial applications. Can be associated with DDA 800 series residual current circuit breakers.
