Tii’s Totel Failsafe® Station Protector Modules are the basic components of Tii Station Protectors, and the 355M Maximum Duty Protector provides years of reliable protection against power surges and the damage they can cause.
KEY PRODUCT BENEFITS
- 355M module is entirely self-contained and consists of a Maximum Duty three-electrode gas tube surge arrester, a failshort mechanism, and a backup airgap
- Entire assembly is completely encapsulated to prevent moisture entry and environmental contamination
- Comes with a corrosion-resistant ground strap and two threaded binding posts for service wire and station wire connection
- Surge protection is provided in three ways:
1. The gas tube operates on over-voltage surges and shunts the transient to ground
2. The failshort device operates under power cross conditions to permanently ground the line
3. The backup airgap provides surge protection in the unlikely event should the gas tube arrester vent - 355M module may be employed in a variety of single and multiple pair protector and network interface device assemblies
- Gas tube recovers after a surge and remains ready for continued normal operation for many years, reducing maintenance cost over the life of an installation
INDUSTRY STANDARDS
- Listed to UL 497 in the Signal Circuit Protector category when mounted in a Tii Station Protector or Network Interface Device (NID)
- 355M module is accepted as Maximum Duty by RUS when tested to the requirements of PE-80
