Building Entrance Telephone Lightning Protection

Before we dive into the Circa product let’s talk about why you need protection.┬áThe National Electric Code Article 800, and the Canadian Electric Code Section 60, Subsection 200 and 202, requires the use of surge protection for telephone lines. Today’s sensitive telecommunications equipment requires more protection than ever to safeguard it against damage caused by lightning or electrical surges. Circa Building Entrance Terminals help to protect your equipment investment with sizes and features that adapt to your special needs. Daily fluctuations in current can wear down, and eventually destroy, fragile circuitry before its time.

How is this protection used?┬áCirca’s protectors are designed for flexibility that assures a perfect fit for your business, residential and campus applications. We offer a variety of capacity options (1, 2 , 6, 10, 12 , 25, 50, 100, 200 and 300 pair sizes) that can be deployed in multiples for high pair count applications. Circa Building Entrance Terminals (BET’s) are both rack and wall-mountable. Input/output options include 110 connectors, 66 blocks, BIX connectors, swivel stubs, RJ21X connectors and pre-connected MS2 or 710 connectors. Remember to install a suitable protector on both ends of every exposed line leading into your telecommunications and networking equipment, whether aerial or buried. Proper grounding is essential for rated performance of protection circuitry.

Let’s take a look at some of the different size blocks and fuses that go along with them from our YouTube channel.

These are just a few examples of Circa’s offerings. You can order these or if you have a Circa part number that is not on the site contact us and order online.
