Feed-through terminal block, PUSH IN, blue, 1.5 mm², 17.5 A, 500 V, number of connections: 4, A4C 1.5 BL 1552700000

Tool-free wire connections

The A4C 1.5 BL feed-through terminal block utilizes PUSH IN technology from the Klippon Connect line - a solution that allows for direct insertion of the wire into the terminal without the use of tools. Simply insert the cable and you have a connection - this will be particularly appreciated during repetitive assembly work in industrial control panels.

The design allows for modular installation expansion. Each level features two connection points, providing a total of four connections per block.

Materials and environmental resistance

The contacts are made of hardened steel - this feature ensures the terminal maintains contact pressure even under repeated thermal and mechanical stresses. The conductive elements are coated with tin, which guarantees low contact resistance and connection stability over long-term operation.

The housing is made of WEMID plastic, which is characterized by temperature resistance from -60°C to 130°C. The material is halogen-free, which limits the emission of toxic gases in the event of a fire - an important feature in installations requiring safety certification.

The block meets the requirements of UL94 V0, CSA, and ATEX standards, confirming its suitability in explosion-hazardous zones and in applications requiring material flammability class verification.

Operating parameters and applications

A rated cross-section of 1.5 mm² at a current of 17.5 A and a voltage of 500 V places this model in the category of compact terminals for light control circuits and signal distribution. It is effective in machine control panels, industrial automation installations, and applications requiring organized wiring in small spaces.

To expand multi-pole sets, ZQV cross connectors can be used - available in various colors (orange, red, blue), they allow for the rapid creation of connection groups without additional wiring.

According to the manufacturer's technical documentation, the block fits TS 35 type DIN rails and is compatible with AEB/ZEW series mounting accessories used throughout the Weidmüller A-Series Push-In product family.

The blue housing facilitates the identification of neutral or signal paths in the installation - a standard color coding used by panel manufacturers and automation integrators worldwide.
