FireLite ESD100 Ethernet Data Line Protector


Our Price : $324.59

Product Code: ESD100


The Alerton ESD-100 is an Ethernet data line protector, which protects equipment connected to unshielded twisted pair (UTP) Ethernet networks from transient voltage. Use the ESD-100 on 10Base-T or 100Base-TX Ethernet networks.

The ESD-100 is a low capacitance, two-stage transient voltage protector that provides primary and secondary protection against lightning, inductive switching, and electrostatic discharge (ESD). The first stage directs the transient current through the ground terminal return path, and the second stage clamps the voltage to a safe level without interrupting service. The ESD-100 is designed to protect circuits from common-mode (line-to-ground) and differential (line-to-line) transients.

An RJ-45 modular jack provides a simple connection to the network, and a pigtail lead with an RJ-45 plug provides connection to the protected equipment. For maximum protection, a 14 AWG grounding wire provides connection to a known good earth ground at the equipment panel.A keyhole mounting system on the back of the unit simplifies installation.

Use the ESD-100 in combination with the BTI-S global controller in smoke control applications. Also use it to protect equipment in harsh environments where electrical transients are common.
