Panel-mount terminal block DTB-1E35 series

DIN rail-mountedscrew connectionhigh-current

Overview
1-pole, 2-conductor junction block DTB-1E35 designed for secure connection of two copper or aluminium conductors from 2.5 to 35 mm². Rated current: 135 A (Cu) / 120 A (Al). Tinned aluminium conductor body and conductive grease supplied to optimise contact.

Function
The power junction block provides a reliable connection for two conductors (Cu/Al) in high-current power circuits. Ensures electrical continuity and mechanical retention suitable for industrial and commercial electrical panels.

Applications
Ideal for industrial and commercial electrical panels, power cable connections, distribution terminals or electrical equipment requiring a compact and secure installation.
