Characteristics
Citel B 180 and B 280 surge protectors have been designed to protect your single and dual telephone and data lines against harmful lightning surges and electrical transients. The two-staged protection circuit consists of a combination of powerful gas-tube technology and fast switching diodes. These compact boxes are designed for wall mounting and screw connection.
