Schneider Electric NSYTRV22 Linergy TR 2.5 mm2 Terminal

NSYTRV22: Linergy TR 2.5 mm² feed-through terminal block

The NSYTRV22 is a Schneider Electric Linergy TR terminal block of the TRV screw-terminal series, supplied in a set of 50 pieces and described as a feed-through type with clip-on rail mounting. The colour is grey and the nominal cross section is 2.5 mm². Seven Star LLC supplies it from Muscat as an independent supplier to panel builders, system integrators and maintenance stores in Oman and the GCC.

At 2.5 mm² nominal, this unit is the lightest feed-through in this group and the one that fits the smallest control wiring: 24 V DC supplies, signal pairs and low-current auxiliary circuits. Its body is only 5.2 mm wide, so a long run of them fits on a short rail. The reading of the reference here follows the datasheet title only: TRV is the short name for the screw-terminal family, and the digits in the code track the cross section in the title. The datasheet does not publish a decoding table.

Comparison of the NSYTRV22 with other TRV blocks

Width grows with current: from 5.2 mm at 2.5 mm² to 20 mm at 50 mm², so rail length planning must follow the mix of sizes in the panel.

Selection checklist for the NSYTRV22

• Conductor size: confirm the cable fits 0.14–4 mm² solid, with or without cable end / 0.2–2.5 mm² flexible with cable end.
• Current and voltage: check against 24 A (IEC), 20 A UL/CSA at 1000 V (IEC 60947-7-1), 600 V UL/CSA.
• Pack size: the reference is sold as a set of 50, so count pieces in sets.
• Width: 5.2 mm per block; measure the available rail length.
• Accessories: add end clamps, covers and bridges if the layout needs them.
• Approvals: verify that the project approval appears on the datasheet.

Compatibility and related parts for the NSYTRV22

The datasheet lists compatibility with Spacial enclosures and with the ranges PrismaSeT G, PrismaSeT P, PrismaSet HD, PrismaSeT Pack 250, PanelSeT, Mureva, PrismaSeT XS and TeSys. The matching accessories of the Linergy TR family include end clamps such as NSYTRAABV35, end covers such as NSYTRAC162 and NSYTRAC22, and plug-in bridges such as NSYTRAL410 and NSYTRAL420; check each accessory datasheet against the block width and cross section before ordering.

Siblings of this unit in the same screw-terminal series are NSYTRV42 (4 mm²), NSYTRV42PE (4 mm² earth), NSYTRV42SF5 (fused), NSYTRV62 (6 mm²), NSYTRV502 (50 mm²). They look alike on a rail, so colour, width and printed marking should be checked when mixing sizes.

Installation and maintenance of the NSYTRV22

Clip the block onto the rail, keep the screws backed off until the conductor is in place, then tighten to 0.5–0.6 N.m. Re-tighten once after the first thermal cycles because stranded copper settles under the clamp. Where a flexible conductor is used without a cable end the datasheet allows it, but ferrules give a neater clamp and are good practice for vibrating panels.

In Gulf installations the typical failure is a loose screw on a heavily cycled circuit, not a defective block. Include the terminal rows in thermographic surveys, and keep spare sets of this unit in stock so a damaged block can be replaced without waiting for a shipment.

Typical uses of the NSYTRV22 in Oman and the GCC

Terminal blocks of this class are used inside marshalling cabinets, MCC control sections, lighting panels and building-services panels across oil and gas, power, desalination and petrochemical sites. Small signal and control wiring such as field instruments and relay coils is the main use here. The wide temperature rating of the polyamide case suits warm electrical rooms in the region.

Electrical and material data for the NSYTRV22

Rated operational voltage is 1000 V (IEC 60947-7-1), 600 V UL/CSA. Rated current is 24 A (IEC), 20 A UL/CSA. The insulating case is polyamide 6/6 with a UL 94 flame retardance of V0 at 0.8 mm, a dielectric strength of 1000 V per IEC 60243-1 and a comparative tracking index of 500 CTI. The datasheet gives an operating range of -40 to 130 °C, a wide window that suits warm electrical rooms. Net weight is 8.2 g per piece.

Approvals shown on the datasheet are VDE, UL, DNV, CSA, GL. Always check that the approval you need on a project is listed for this exact reference before specifying it on a drawing.
