The DECA terminal blocks of the MA series can be ordered with a 3.5 mm, 5, 7.5 and 10 mm pitch, and can have between 2 and 24 positions. They contain wire-protection clamps, that ensure cost-effectiveness, accurate dimensions, and corresponding use for different wring solutions. The 2&3 pole modular design offers quick connection for higher pole number assemblies, depending on the applications. If requested, they can be delivered with the one-piece housing (mass quantity). The MA series offers screw connections for conductor diameters up to 1.5 mm2. The wire connection fixture is via brass or copper alloy, offering minimal vibrations, tight screw connections, corrosion resistance, and a maintenance-free operation. After turning the clamping screw, Leaf Spring is pushed until a secure location, without making damage to the conductor or conductor stands. MA blocks are UL, CE, and VDE certified.
