Solarmi AC/DC circuit breaker 50A for photovoltaics, ABB CIRCUIT BREAKER S 201 C 50 NA, DC disconnector

Xtend Solarmi ABB S201-C50NA

Modular AC/DC (50 A) circuit breaker S200 series (model S201-C50NA) with neutral disconnection. Characteristic C - Control and protection of circuits against overloads/short circuits and protection of resistive and inductive loads with low inrush current.

These circuit breakers have two different tripping mechanisms, a delayed thermal trip for overload protection and an electromechanical trip for short-circuit protection. All MCBs in the S200 product range comply with IEC/EN 60898-1, IEC/EN 60947-2 and UL1077 , allowing them to be used in residential, commercial and industrial applications.

•
