Rated current: 24A
Rated voltage: 800V
Connection type: 2-conductor
Mounting type: DIN rail
Color: Dark gray
How to use
To install the terminal block, snap it onto a standard DIN rail until it clicks securely into place. Strip the insulation from your conductors to the recommended length and insert them into the terminal points. Ensure the wires are fully seated and tightened according to the manufacturer's torque specifications to establish a permanent and safe electrical connection. Multiple blocks can be arranged side-by-side to accommodate complex wiring layouts.
What to consider before purchase
Verify that the 2.5mm2 wire size matches your specific application requirements.
Ensure the DIN rail type in your enclosure is compatible with the mounting mechanism.
Check that the 24A current and 800V voltage ratings meet the electrical load demands of your circuit.
Usage recommendations: Always ensure that the power supply is disconnected before performing any wiring or maintenance on the terminal block to prevent electrical hazards. Use appropriate wire ferrules if necessary to ensure a uniform connection.
