Feed-through terminal block, PUSH IN, orange, 2.5 mm², 24 A, 800 V, number of connections: 3, A3C 2.5 OR 1521830000

Maintenance-free wire connections in industrial installations

The PUSH IN feed-through terminal block enables fast and secure connection of single-wire and multi-wire conductors without the use of tools. Push-in technology eliminates the need for tightening screws - simply insert the prepared wire end into the connection hole, and the spring mechanism automatically ensures stable contact. This solution significantly accelerates assembly and service work, reducing the time required to make connections in switchgear and control cabinets.

Construction and contact durability

The contacts are made of tin-plated copper, which guarantees low contact resistance and corrosion resistance - essential in industrial conditions where humidity and chemical substances can degrade electrical connections. The hardened spring steel of the clamping mechanism maintains clamping force even after multiple insertion and withdrawal cycles of the wire - the contact does not "loosen" over time, which is a common problem in cheaper alternatives.

The housing in an intense orange color facilitates the identification of neutral or signal paths in complex installations.

Operating parameters and compatibility

The device operates at a cross-section of 2.5 mm², a maximum current of 24 A, and a voltage of 800 V - typical values for control circuits and power distribution in industrial machinery. The block is mounted on a standard DIN rail TH35, ensuring compatibility with most switchgear on the market.

The number of connections, amounting to 3, allows for the creation of circuit split points without additional intermediate elements - the wire passes through the block, and an additional third hole enables branching or measurement.

A weight of only 15 grams means the block does not burden the cabinet structure even with a large number of connections - important when designing lightweight modular switchgear.
