The 1012300000 is a Fused Terminal Block with screw connection, 6mm² wire cross section area and fuse isolator with LED for screwable cross section. M3.5 clamping screw and 12mm stripping length. Dark beige color, TS 35 rail mount and snap-on mounting. The WSI 6/LD 60-150 DC/AC terminal block accepts 20AWG minimum to 8AWG maximum wire size. Hardened steel for mechanical strength and high-quality tinned copper for optimum conductivity. All materials have been tested to current environment guidelines. The W-Series offers solutions for all standard electrical functions. It brings considerable time savings compared to all other screw terminals on the market. Thanks to the patented design of Weidmüller's W-series screw connection technology it is possible for two conductors with the same cross-section to be connected in one and the same clamping yoke without difficulty.
