CITEL BB surge arresters are ceramic gas discharge tubes designed to protect telecommunication and data transmission equipment against transient overvoltages caused by industrial overvoltages and lightnings. The BB series is available in bare version for connector block mounting , or in axial output throught in plated leads (for PCB mounting).
