# AlarmEMC-240B
120/240 Single/Split-Phase

The EMC is a rugged, highly reliable panel surge protector for residential or commercial standard 120/240V single- or split-phase applications.

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

After a surge, the suppressor automatically recovers and is ready for the next surge. In a rare event of MOV failure, the fuse opens and the indicator LED extinguishes.

FEATURES
• Fast Response Time
• 40,000 Amps Per Phase Capacity
• Failsafe and Fused
• Operational Status Indicators
• UL 1449 Listed
