Product Description:

The 0TB1310.3100 is a terminal block assembly produced by B & R Automation within the 0TB Terminal Blocks series. Designed for control cabinets and signal distribution islands, this component groups field wiring and controller wiring onto a removable interface. In automated lines, it serves as a fixed junction that organizes conductors, simplifies service access, and sustains reliable contact pressure for sensors, actuators, and low-power supply circuits. The removable layout also helps keep machine-side wiring separated from cabinet-side wiring when individual circuits need to be isolated or rearranged.

Each section of the block follows a 3 x 10-pin configuration, so three identical rows provide a total of 30 connection points on a compact footprint. The inter-pin pitch of 3.5 mm sets the spacing between adjacent conductors and the overall width of the block, which matters when planning DIN-rail space. Rated insulation supports working potentials up to 300 V, permitting direct connection of control-level power without additional isolators. Path resistance remains below 4.2 mΩ, limiting I²R losses and voltage drop along short signal routes. That low resistance helps preserve signal quality in short command and feedback runs where unnecessary voltage loss can affect device response. Current paths use tinned copper conductors that resist corrosion and maintain stable electrical contact during repeated use.

For load flow calculations, the assembly carries a nominal load of 5 A per channel, which matches typical sensor loops and small inductive devices. The clamp accepts a rated cross-section of 1.5 mm², so stranded or solid wires in this range can be inserted without ferrules. Termination is achieved through the spring-loaded Cage Clamp mechanism, allowing tool-free insertion while maintaining constant pressure over temperature swings and vibration. Because the clamping force remains consistent without retightening, the connection stays stable in panels exposed to thermal cycling or routine movement. Final retention to the mounting rail is reinforced by a Screw Flange, a mechanical feature that helps prevent loosening when panels experience acceleration or seismic motion.
