Abstract: An individual subscriber circuit protector module (10) employing solid state circuitry (16) for protection against momentary voltage surges, and having heat coil assemblies (17) for protecting against continuous excess current surges. Fail-safe protection (13) is also provided which becomes operative in the event of failure of the heat coil protection.

Abstract: An individual telephone subscriber circuit module for use with laminar type connector blocks employing conventional three-element gas tubes of diameter greater than the thickness of an individual lamina. The module houses two gas tubes (19, 20) in side-by-side relation and straddles two adjacent laminae on the block to protect a pair of adjacent circuits.
