1. A telecommunications line surge protector comprising:
- a housing;
a first input connector connectable to a telecommunications line;
a first output connector connectable to a telecommunications line;
a first surge protection circuit, disposed within the housing, which connects the first input connector to the first output connector by at least two wires, including a first surge protection element that protects at least one wire from surges greater than a first limiting voltage, and including a second surge protection element that protects at least one other wire from surges greater than a second limiting voltage, where the first limiting voltage is different from the second limiting voltage;
a second input connector connectable to a telecommunications line;
a second output connector connectable to a telecommunications line; and
a second surge protection circuit, disposed within the housing, which connects the second input connector to the second output connector by at least two wires, including a third surge protection element that protects at least one wire form surges greater than a third limiting voltage, and including a fourth surge protection element that protects at least one other wire from surges greater than a fourth limiting voltage, where the third limiting voltage is different from the fourth limiting voltage.

11. A telecommunications line surge protector comprising:
-
a housing; a first input connector connectable to a telecommunications line; a first output connector connectable to a telecommunications line; a first surge protection circuit, disposed within the housing, which connects the first input connector to the first output connector by at least two wires, including a first sidactor having a first limiting voltage, and including a second sidactor having a second limiting voltage, where the first limiting voltage is different from the second limiting voltage; a second input connector connectable to a telecommunications line; a second output connector connectable to a telecommunications line; and a second surge protection circuit, disposed within the housing, which connects the second input connector to the second output connector by at least two wires, including a third sidactor having a third limiting voltage, and including a fourth sidactor having a fourth limiting voltage, where the third limiting voltage is different from the fourth limiting voltage first modular connecting means on the housing for detachably connecting the telecommunications surge protector to a second surge protection module; and a grounding strip which is electrically connected to a ground path in the second surge protection module when the telecommunications surge protector is connected to the second surge protection module by the first modular connecting means, and which provides grounding for the first and second surge protection circuits.
