## Detailed Specifications:
1. Connection Type (Screw Connection):
* The Phoenix Contact 2903335 terminal block uses a screw connection method for making electrical connections. This provides a highly secure and reliable contact, especially in environments subject to vibration or mechanical stress. The screw connection also allows for easy maintenance and reusability, as connections can be quickly tightened or loosened using a screwdriver. This connection type is ideal for applications where high reliability and durability are crucial.
2. Nominal Cross-Section and Rated Current:
* The terminal block is designed to handle a nominal cross-section of 6 mm², which corresponds to a wire size that is commonly used in industrial systems. This makes it suitable for medium-power applications where stable, high-current connections are necessary.
* It can carry a rated current of 24 A, making it capable of handling significant electrical loads in power distribution or control systems. This current rating ensures that the terminal block can be used in systems with moderate power requirements, providing a stable and reliable connection.
3. Rated Voltage:
* The Phoenix Contact 2903335 is rated for 800 V, making it suitable for medium- to high-voltage applications in industrial settings. This high voltage rating ensures that the terminal block can be used in systems where voltage levels are higher than those typically found in residential or low-voltage applications, such as in electrical control panels, power systems, or industrial machinery.
4. Material:
* The housing of the terminal block is made from polyamide (PA), a high-performance thermoplastic material known for its durability, mechanical strength, and excellent electrical insulating properties. Polyamide is resistant to heat, chemicals, and environmental stress, ensuring long-term reliability and protection for the electrical connections housed inside. The material is well-suited to industrial environments where exposure to heat, oil, and other harsh conditions is common.
5. Mounting Type:
* The Phoenix Contact 2903335 terminal block is designed for DIN rail mounting, which is the standard method for attaching terminal blocks to electrical panels or enclosures. This mounting system allows for easy installation and maintenance of terminal blocks in control cabinets or electrical distribution boards. The DIN rail mounting ensures that the terminal block is securely fixed in place, minimizing the risk of mechanical failure or loose connections.
6. Number of Positions and Dimensions:
* The 2903335 terminal block features 2 positions, meaning it allows for the connection of two separate wires or electrical circuits. This makes it a compact solution for situations where only a small number of connections are required, while still providing the necessary electrical conductivity.
* The terminal block has the following dimensions:
* Width: 6.2 mm, which makes it compact and space-efficient when installed on a DIN rail, allowing for high-density wiring configurations.
* Height: 47 mm, making it a suitable choice for control cabinets or enclosures where vertical space may be limited.
* Depth: 50.8 mm, ensuring that the terminal block provides a stable connection and can accommodate thicker wires if necessary.
7. Operating Temperature Range:
* The terminal block can operate in an environmental temperature range of -40°C to +105°C, making it highly versatile for use in both extremely cold and hot environments. This wide temperature range ensures that the terminal block can function reliably in diverse climates and industrial conditions, from outdoor applications in harsh weather to indoor installations in high-temperature areas like power plants and factories.
8. Approvals and Certifications:
* The Phoenix Contact 2903335 terminal block is UL listed, which means it meets the safety standards required for use in the United States and Canada. It is also CE certified, indicating compliance with European Union safety, health, and environmental protection standards. Additionally, the terminal block meets CSA, VDE, and other regulatory certifications, ensuring that it is suitable for use in a wide range of industrial applications globally.
* RoHS compliance further ensures that the terminal block is free from hazardous substances like lead, mercury, and cadmium, aligning with global environmental standards.
