3-tier terminal block, PE/through/through terminal block, with push buttons, 2.5 mm², PE/N/L, for Ex e II applications, without marker carrier, for TS 35 x 15 and 35 x 7.5 mounting rail, Push-in CAGE CLAMP®, 2.50 mm², gray 2202-3217

Universal rail connector for safe and efficient wire connection

This three-tier rail connector, designed for wires with a cross-section of 2.5 mm², is a reliable solution for both professional installers and end-users. The connector combines the functions of a PE protective connector, a through connector, and a standard connector, providing versatility in various electrical installations. The buttons facilitate operation and allow for quick identification of individual circuits.

The connector is designed to operate in potentially explosive atmospheres (Ex e II), making it an ideal choice for industrial and specialized applications. Made of high-quality thermoplastic, it is characterized by durability and resistance to external factors. Mounting on TS 35 x 15 and 35 x 7.5 rails is quick and intuitive, and Push-in CAGE CLAMP® technology guarantees a secure and maintenance-free wire connection.

Design and application

The connector allows connection of PE (protective), N (neutral), and L (phase) wires in one module. This arrangement minimizes space occupied in the distribution box and simplifies the connection diagram. Thanks to the possibility of mounting on standard DIN rails, integration with existing infrastructure is extremely simple. The connector is compatible with both solid and stranded wires – with and without ferrules.

It is worth noting the flame retardancy class V0 of the insulating material, which ensures a high level of safety in the event of a short circuit or overheating. The connector width of 5.2 mm allows for dense packing of modules in the distribution box, which is particularly important in applications with limited space. The lack of a label carrier allows for individual circuit labeling using dedicated labels or markers.
