BOXTRAB surge protective devices
BOXTRAB is a state-of-the-art surge protective device (SPD) that combines protection for power, data, and signal - all within the same enclosure. Phoenix Contact has offered various BOXTRAB products over the years, and this update delivers an expanded family with the same great protection and groundbreaking features – now configurable and field-upgradeable. Also, for the first time, the family offers high-quality 316L stainless-steel enclosure versions for industrial processing applications involving chemicals. This provides a higher corrosion resistance, especially against chlorides and chlorinated solutions.
Features and benefits
Expand the possibilities. The most unique feature of the BOXTRAB series is the ability to custom-configure and field-upgrade the product to meet your precise needs. With all the different expansion options available, BOXTRAB offers a flexible solution for virtually any combination of power, data, and signal. Simply select the desired protector for your application and install it in the enclosure. The expansion parts include protection for data and signal architectures including 4-20mA, 0-24V, CCTV, Ethernet, PoE, HART, IO-Link, Modbus/TCP, PROFIBUS, PROFINET, RS-232, RS 485, temperature measurements, and many more.
These add-on devices include a variety of Phoenix Contact’s UL Listed isolated loop, common reference (digital), and data protectors. Simply select the desired protector for your application and install it in the enclosure.

A single solution. Water/wastewater and process industries use instrumentation that requires both power and signal/data control lines. In the most common types of these applications (120 V AC power plus 4-20mA signal) customers often use two enclosures: one for power and one for signal. The benefit of using BOXTRAB is that they now have a single complete unit to protect power and data/signal for instrumentation in one enclosure instead of two. BOXTRAB offers a space-saving, cost-effective solution requiring less time to design-in and install.
Quality enclosures
Quality enclosures. BOXTRAB is available in either a polycarbonate or stainless-steel enclosure. Both enclosures are NEMA 4X outdoor-rated. The metal enclosure, identified as 4XS, is made of 316L stainless steel. 316L stainless steel is commonly used in industrial processing applications involving chemicals. It provides a higher corrosion resistance, especially against chlorides and chlorinated solutions. 316L stainless steel is marine-grade, which is a better choice for applications where salt exposure is an issue to avoid a potential chemical reaction with the metal. It is ideal for applications in wastewater, marine, and food-processing wash-down. In addition, the stainless-steel versions have an externally mounted LED providing visual indication of the status of the power SPD inside.
The polycarbonate enclosure, identified as 4XP, has multiple knockouts to allow for easy wiring. The clear cover allows easy viewing of SPD status without the need to open the enclosure. The cover is also UV resistant. This eliminates the “cloudy” effect from sun exposure that makes viewing the contents inside difficult.
Product offering
The BOXTRAB series offers 14 standard configurations available in either the polycarbonate enclosure or the 316L stainless steel. Four are power only, each with a different power PLT-SEC surge protective device. The other three are power and signal combinations. All versions can be customized or upgraded in the field as required for specific applications.
