Phoenix Contact 1045923 Terminal Block Accessory, 2-Position Distribution Block, 1.5 mm²

The Phoenix Contact 1045923 is a professional-grade distribution block engineered for efficient power distribution in industrial electrical installations. This compact 2-position terminal block is designed to streamline wiring in control cabinets and automation systems, offering a reliable connection point for electrical circuits. Its robust construction and precise engineering ensure long-term stability and performance in demanding environments.

Advantages

This distribution block utilizes an advanced push-in connection technology that significantly reduces installation time by allowing for tool-free conductor insertion. The compact design maximizes space within crowded control panels, while the high-quality materials provide excellent electrical conductivity and mechanical durability. Its standardized grey color coding helps in organizing complex wiring systems, ensuring clear identification and maintenance efficiency.

Suitable for

• Industrial control cabinet wiring
• Automation and control systems
• Power distribution in electrical panels
• Modular electrical installations

This component may not be suitable for applications requiring high-power distribution beyond its 17.5 A current rating or for environments exposed to extreme chemical or thermal conditions that exceed the specified material tolerances. It is also not intended for direct connection to high-voltage mains without appropriate protective housing and safety measures.

Key specifications

• Nominal voltage: 450 V
• Nominal current: 17.5 A
• Connection method: Push-in connection
• Number of connections: 2
• Cross-section range: 0.14 mm² to 2.5 mm²
• AWG range: 26 to 14
• Width: 4.2 mm
• Height: 17.7 mm
• Mounting type: DIN rail adapter
• Color: Gray

How to use

To install the distribution block, snap it onto a compatible DIN rail adapter within your enclosure. Once mounted, strip the insulation from your conductors according to the required length and insert them directly into the push-in connection points. The internal spring mechanism automatically secures the wire, ensuring a gas-tight and vibration-resistant connection. To release the wire, use a standard screwdriver to actuate the release mechanism.

What to consider before purchase

• Verify that the 17.5 A current rating meets your circuit requirements.
• Ensure the DIN rail adapter is compatible with your existing mounting setup.
• Check that your conductor cross-section falls within the 0.14 mm² to 2.5 mm² range.
• Confirm the space availability in your control cabinet for the 4.2 mm width per block.

Usage recommendations

Always ensure that the power supply is disconnected before performing any wiring operations. Use appropriate wire ferrules for stranded conductors to ensure optimal contact quality and long-term reliability in high-vibration environments.
