Main & Sub-Panel Protectors

Replaced by the new PTS 208 3Y H UL-L 2nd Edition 300KA Rating plus a 330V let through Rating

Main and sub-panel surge suppressors usually come in two general types; series protectors and parallel protectors. Series protectors are load bearing devices and have to conform to the current the power company delivers to the main or sub-panel. Parallel protectors are non-load bearing devices and therefore can be used regardless of current delivered to the main or sub-panel.

Series protectors are usually very expensive and require breaking the incoming line to install. Parallel protectors are usually installed on the load side of the main breaker and are quite efficient.

Underwriters Laboratories (UL) under 1449, has chosen to rate surge suppressors in pass-through voltage categories. There is one serious fault in their testing. Some manufacturers of parallel type surge suppressors utilize plug-in modules, which allow for the replacement of damaged modules. The ratings are obtained at the module itself without consideration for the length of wire required for the installation. A module rated at 400 volts pass voltage with an additional two feet of wire added for the installation actually becomes a 1000 volt pass voltage. When placed in a 24" X 24" box, two feet of wire would be minimal for the installation, therefore ratings of this modular type panel protector can be deceptive.

Surge suppressors are designed to protect the electrical and electronic equipment to which they are connected. In rare cases, when extremely large surges occur, the surge suppressor will be sacrificed to save the protected equipment. This is the purpose of a surge suppressor. Some surge suppressors claim to have a rating of 100,000 amps or more. The ANSI/IEEE 587 and UL ratings have a maximum test of 10,000 amps. This is more than adequate for the main service electrical entries.

The measurement of a surge suppressor's performance is the pass voltage (actual voltage) your equipment sees after a suppressor does its job. High current ratings do not mean low pass voltage. E-Clips surge suppressors have a lifetime warranty and have been protecting customer facilities and equipment for 16 years. During this time, E-Clips' customers have experienced no equipment losses.
