The SL1411A Series is a new addition to the Delta family of gas plasma arresters designed for superior protection of outside plant equipment used in telecommunications applications.

New from Littelfuse, the SL1411A Series is a new addition to the Delta family of gas plasma arresters designed for superior protection of outside plant equipment used in telecommunications applications.

Littelfuse's new SL1411A Series is ideally suited for use in outside plant protector modules to meet the requirements of GR-1361, RUS PE-80, ITU K.12 and YD/T940, 950, 1082, 993, 694.

Rated at 10kA/10A AC, the SL1411A is a two-terminal gas discharge tube specifically designed to protect highly exposed external equipment that typically demands high energy, long life and high durability protection devices.

Using newly enhanced materials, Littelfuse has created a durable device that combines a high surge rating with low voltage clamping not typically found in competitor devices.

The SL1411A joins the SL1026 Series (capable of dealing with surges up to 55kA) as part of the Delta family of high surge, high durability protectors.

The superior surge clamping capability of the SL1411A Series reduces the transient to the lowest possible level, minimising the need for telecomms system maintenance.

The SL1411A can be exposed to repetitive 10kA pulse while maintaining a stable breakover voltage.

This ensures the quality of protection while enduring multiple exposures to transients.

The combination of low clamping and a stable level of protection after multiple transient pulses helps prevent failure and damage to the outside plant applications, reducing the stress placed on secondary protection devices.

This helps to improve system up time and reduce repair costs.

The addition of the SL1411A Series supports the Littelfuse product strategy of offering a complete line of gas plasma arresters that provide protection across the entire telecomms equipment chain.

Surface mount devices are also currently available.

Littelfuse gas plasma surge arresters are lead-free and RoHS compliant.
