This series provides point-of-use protection, at the dedicated
equipment level, against damaging transients. Ideal for
installation in electronic control cabinets found in harsh
industrial environments such as the factory oor or at remote
locations. These devices provide 50,000 amps of surge
protection, sinewave tracking, LED status indication and
form “C” dry contacts. This DIN Rail series also provides
protection on all electrical paths and comes with
a standard ten year product warranty.
Applications (20 Amp Max)
• Control Cabinets for Industrial Automation
• Point-of-Use Industrial/Service Equipment
• Remote Commercial or Industrial Equipment
