120/240V 1PHASE PANEL TVSS SYSTEM 

The EMC-240B is a rugged highly reliable panel surge protector for residential/commercial STD. 120/240V 1PHASE applications.

The EMC-240B features totally solid-state construction for reliability and quick response to surges. Two advanced, metal oxide varistors (MOV) are the primary protective elements. These MOV's are each capable of 40,000 amps of surge current.

The protection components are designed to fail shorted and are fused. After a surge, the suppressor automatically recovers and is ready for the next surge. In the rare event of MOV failure, the fuse opens and the indicator LED extinguishes.
