Phoenix Contact TERMITRAB Ex e Zone 1 Terminal Block

The Phoenix Contact TERMITRAB is an ATEX and IECEx dual-certified Ex e (increased safety) terminal block for Zone 1 and Zone 2 hazardous area applications, rated for 2.5 mm² conductors at 24 A / 500 V within IEC 60079-7 compliant Ex e certified enclosures. The TERMITRAB meets all IEC 60079-7 Ex e requirements: minimum 8 mm clearance and 12 mm creepage at 500 V (Pollution Degree 2), gas-group IIC suitability, a torque-marked positive-locking screw ensuring the specified 0.5 N·m installation torque, and temperature class T4 to T6 suitability depending on the ambient operating temperature. The dual ATEX and IECEx certification marks cover the full Saudi regulatory environment — ATEX is referenced in the IEC 60079-series based Saudi standards administered by SASO, while IECEx is directly referenced in Saudi Aramco engineering standard SAES-J-901 and accepted by ARAMCO's Facility Engineering team for hazardous-area panel approvals throughout the Kingdom.

The TERMITRAB product name itself is an abbreviation of the German "Terminalblock for Trabtech" (Trabtech being Phoenix Contact's original surge protection brand), which reflects the product's hybrid origin as a terminal block with optional integrated surge protection inserts. The base TERMITRAB screw-clamp terminal (model 2812688) provides the Ex e termination function, while optional TRABTECH SPD inserts can be snapped into the TERMITRAB carrier rail to add surge protection to selected signal loops without increasing the per-loop footprint — a capability unique to the TERMITRAB system that combines Ex e terminal block and SPD into one DIN rail position. This integrated SPD option is particularly valuable in Saudi field junction boxes on ARAMCO wellheads and GOSPs in the Ghawar and Khurais fields, where lightning-induced surges on long instrument cable runs must be suppressed at the Ex e enclosure entry point without violating the Ex e certification of the terminal block or requiring separate SPD space in the already-cramped junction box.

The TERMITRAB's combination of SAES-J-901 CLIPLINE brand recognition and IECEx hazardous-area certification makes it the reference product for Ex e terminal blocks in Saudi Aramco's instrumentation engineering community. Saudi Aramco FEED engineering packages for new GOSP, gas-compression, and offshore topsides facilities specify "Phoenix Contact TERMITRAB or approved equivalent" for Zone 1 field junction box termination — establishing the TERMITRAB as the baseline that competing ATEX terminal products must be approved against. SABIC's Jubail petrochemical complex ATEX panel designs specify Phoenix Contact TERMITRAB as the primary Ex e terminal for their Zone 1 and Zone 2 classified process-area field junction boxes, a specification maintained across SABIC's engineering standard revisions since the 2000s. The NEOM OXAGON industrial port, which includes hazardous-area classified process zones for bulk chemical handling, specifies TERMITRAB for its Zone 1 field panel installations.

Razz Middle East maintains TERMITRAB stock in Jeddah and Riyadh, along with the complete TRABTECH SPD insert range for integrated surge protection configurations. We maintain a current library of Phoenix Contact TERMITRAB IECEx and ATEX certificates in English and Arabic translation, ready for direct submission to ARAMCO Facility Engineering or SABIC HSE for hazardous-area panel approval. Our technical team provides Ex e enclosure sizing and layout guidance, TERMITRAB SPD insert selection for ARAMCO GI-0476 compliance, and installation torque verification training for panel fabricators and ARAMCO inspection engineers. All TERMITRAB Ex e supplies carry Phoenix Contact IECEx and ATEX certificates, CE declarations, and SASO import conformity documentation.
