MH-2201

Lightning Surge Protectors for
Electronics Equipment M-RESTER

LIGHTNING SURGE PROTECTOR FOR
POWER SUPPLY USE
(200 V / 220 V / 240 V AC, single phase)

Functions & Features
• Designed for installation where AC power enters the control panel for relatively large power consuming equipment such as large instrumentation panels, computer systems or telemetering systems in central control rooms or operation centers
• Composed of air-core reactors, large capacity discharge elements and electromagnetic contactors
• Thermal fuse in parallel with the discharge element opens and cuts off the operating circuit for the electromagnetic contactor in case of discharge elements failure, thus protecting the equipment connected to the arrester

MODEL: MH–2201

ORDERING INFORMATION
