3-tier terminal block, with push-in mechanism, through-hole terminal block, L/L/N, without marker base, for Ex e II applications, wire entry holes per tier, blue printing, for TS 35 x 15 and 35 x 7.5 DIN rail, 2.5 mm², Push-in CAGE CLAMP®, 2.50 mm², grey 2202-3203

Industrial installations

The WAGO TOPJOB® S DIN rail terminal block is an advanced device designed for professional electrical applications in industrial environments. The three-phase/neutral configuration L/L/N design enables the creation of complex electrical connections while maintaining compact dimensions. Thanks to Push-in CAGE CLAMP® technology, installation is tool-free – simply insert the conductor to achieve a secure and permanent connection.

The product features Ex e II explosion protection certification, allowing its use in potentially explosive zones. Made of high-quality PA66, it ensures mechanical and chemical resistance as well as a flammability rating of V0 according to UL94. The gray color scheme facilitates identification within installations.

Electrical parameters and operating range

The device operates at a rated voltage of 500V and supports conductor cross-sections from 0.25 mm² to 4 mm². It accommodates both solid and stranded conductors (with or without a ferrule). The rated current is 22A, and the maximum current at the largest cross-section is 26A.

The operating temperature range is from -60°C to +105°C, enabling use in extreme environmental conditions. The conductor stripping length should be 10-12 mm. The design provides an impulse withstand voltage of 6 kV and overvoltage category III.

Construction and mounting dimensions

The compact dimensions of the device are 5.2 mm width, 93.6 mm height, and 69.5 mm depth. Mounting is performed on a standard DIN rail TH-35 mm (both 35×15 and 35×7.5 mm). Each level contains two connection points.

The insulating material belongs to group I according to international standards. Control elements are orange for easy identification. The device weight is only 17.5 g, which minimizes the load on the mounting rail.

Regulatory compliance and certificates

The product meets the requirements of the IEC/EN 60947-7-1 standard and holds the following certificates:

• CCA (Conformity Assessment)
• AEx (Underwriters Laboratories Inc.)
• CCCEx (CQST/CNEx)

The explosion protection certification confirms its suitability for applications requiring the highest safety standards. The device is covered by the EU Declaration of Conformity and UKCA.
