A surge protector having a first hot line, a first load line, a second hot line, a second load line, and a ground line, the surge protector comprising:
- a differential mode protection circuit coupled between the first hot line and the second hot line;
- and
- a common mode protection circuit coupled to the first hot line, the second hot line and the ground line.
A surge protector having a first hot line, a first load line, a second hot line, a second load line, and a ground line, the surge protector comprising:
- a differential mode protection circuit coupled between the first load line and the second load line, the differential mode protection circuit having at least one surge suppressor;
- and
- a common mode protection circuit including a first surge suppressor coupled between the first load line and the ground line, and a second surge suppressor coupled between the second load line and the ground line.
A surge protector having a first terminal connection electrically coupled to a second terminal connection, a third terminal connection electrically coupled to a fourth terminal connection, and an intermediate node, the surge protector comprising:
- a first fuse having a line side electrically coupled to the first terminal connection and a load side electrically coupled to the second terminal connection;
- a second fuse having a line side electrically coupled between the third terminal connection and a load side electrically coupled to the fourth terminal connection;
- a differential mode protection circuit coupled between the load side of the first fuse and the load side of the second fuse;
- and
- a common mode protection circuit coupled to the load side of the first fuse, the load side of the second fuse and the intermediate node.
