Shunts and resistors inside traditional junction boxes are typically mounted onto a backing plate in a permanent position and cannot be altered. This backing plate can be a source of frustration when adding, removing, or tightening components because the backing plate must be removed, and cables must be disconnected. This not only requires significant time but can also result in mis-wiring during reassembly. The new Dairyland UltraBox™ introduces a modular approach providing the industry with a junction box design that is convenient and flexible.

Building a Better Junction Box
In place of the backplate limitation, the Dairyland UltraBox™ approach utilizes shunts, resistors and other components that are individually mounted on DIN rails using a unique quick-connect module design. The modular design allows for ease of installation, removal, or repositioning of components anywhere on the DIN rails providing customizability during the initial purchase, and flexibility into the future. A wide selection of industry-standard shunts, resistors, rheostats and isolated measurement terminals are available, all with DIN rail mounting bases.
Adding to its flexibility, the UltraBox™ can be provided with horizontal or vertically oriented DIN rails to make optimal use of the enclosure space as well as to accommodate various cable entry/exit configurations. With the modular approach and new DIN rail mounting system, the UltraBox™ frees CP Technicians from the frustrations and potential mis-wiring that are common during field modifications using traditional junction boxes.
The patented UltraBox™ provides the industry with a new and improved product that is an advanced solution to the frustrations so common with the traditional junction box. Learn More Here

Product Description:
When railroad systems share common corridors with overhead power transmission or distribution systems they are susceptible to damaging power line fault and lightning surge events. The Overwatch HEFPD was designed using our decades of experience in high-energy applications to withstand the powerful, long-duration events caused by AC faults. Developed in response to the new AREMA C&S Manual Part 11.3.7 for High-Energy Fault Protective Devices, Overwatch will protect your track-connected signal and crossing warning systems and prevent costly interruptions.

Product Description
Since 1983, Dairyland has offered the Neutral Isolator as the preferred solution for addressing “stray voltage” on farms. Power utilities who wish to isolate their primary neutral from the customer’s secondary neutral can prevent undesirable primary neutral-to-earth voltage (NEV) from affecting the customer system. Where utilities have concerns about NEV effects on dairy or other livestock operations, the Neutral Isolator offers the most effective and safe solution for separating the two systems under normal conditions, yet solidly re-bonding the two ground grids under lightning or AC fault conditions.
Note: The Dairyland model VTNI is not authorized for use in solving nuisance shock to persons at swimming pools or similar human health situations where structure to ground voltage is present.
Product Description
The patented, customizable UltraBox™ modular junction boxes from Dairyland feature easy access and the ability to add, remove, or reposition components at any time, unlike existing designs using shunts or resistors fixed to a backplane. Featuring moveable DIN rail mounting systems and snap-in modules with industry standard shunts and resistors, users have complete control over the present configuration and future expansion of their product.
Whether configuring an anode junction box, interference bond, rectifier output box, positive/negative splitter, or an enhanced test station box, Dairyland can quickly package and ship the optimum configuration, using standard enclosures and stocked modules containing the most common shunts, resistors, and terminals.
Introduction
Dairyland UltraBox modular junction boxes are a new approach to bonding solutions used in the cathodic protection industry. Instead of permanently-fixtured shunts and resistors found in traditional junction boxes, the UltraBox uses shunt, resistor, and isolated terminal modules which mount to DIN rails via a snapin clip assembly integral to the module. Combinations of modules can be configured as needed on either horizontal or vertical DIN rails. Modules can be added or rearranged at any time, and all hardware and field connections are accessible, overcoming challenges with other industry boxes that require box disassembly to fix loose connections or to add a component. Field wiring connects to the modules via user-installed conduit entries.
