Signal Surge Protection for RS-485 Lines

The Unique-Bargains LRS01-RS485 arrester protects coaxial data transmission circuits from lightning and surge damage. It installs between a PC and the protected device with clearly marked IN and OUT terminals. A secure ground connection is required for proper operation. The unit suits communication systems, repeaters and switchboard equipment.

Sustained Discharge Capacity and Build

The protector handles a maximum discharge current of 10 KA for robust transient suppression. Its aluminium and plastic housing measures 4.8 by 2.5 by 2.5 cm and weighs 75 grams. A 26 cm lead provides flexible placement inside enclosures. The black and silver finish resists corrosion in industrial environments.

Upgrading Unprotected RS-485 Links

This device replaces installations that lack any surge protection on RS-485 data lines. The upgrade is worth it when equipment sits on long outdoor runs or shares ground references with heavy machinery. It is not for buyers who need protection for Ethernet, fibre or high-voltage power conductors.

Questions about this item

Does the 10 kA surge rating generate noticeable heat during continuous use?

The protector is passive and dissipates energy only during a surge event; it produces no measurable heat while idle.

What existing wiring or connectors must I already have to install this unit?

You need an RS-485 data line with compatible terminals and a solid ground connection for the earth wire.

Will the 4.8 cm aluminium housing fit alongside legacy RS-485 gear in a tight cabinet?

Its compact 4.8 × 2.5 × 2.5 cm footprint allows side-by-side mounting with older modules.
