Overview

The WLB Modular Distribution Blocks provide compact, safe and tidy power distribution with an insulated back plate and a transparent protective front cover. They can be mounted on DIN rail or fixed by two screws, and every busbar can be labelled using 3TM. These blocks comply with EN 60947-1 and withstand an ICC peak of 20 kA. Wiring is supported with or without ferrules, covering common conductor cross-sections in industrial panels.

Materials: brass busbars with zinc-plated hardware, PC clear cover, insulated back plate. Ratings include 125 A models (2-bar & 4-bar) and a heavy-duty 160 A model.

Key Features

Connection with or without ferrules; per-bar insulation protection.
Two mounting methods: DIN-rail clip or plate fixing with 2 screws.
Transparent PC front cover; insulated back plate; self-extinguishing design.
Each bar individually labelable (3TM) for quick circuit identification.

EN 60947-1 compliant; ICC 20 kA peak withstand.
Seven models: 2-bar (WLB-207/211/215), 4-bar (WLB-407/411/415), and 3-bar heavy-duty (WLB-413).
Compact footprints from 65×42×50 mm up to 168×138×73 mm.
Clean, professional wiring layouts for multi-circuit distribution.

FAQ

Q1: What standards do WLB modular distribution blocks meet?
A: They conform to EN 60947-1 and can withstand ICC 20 kA peak.

Q2: How can I mount them?
A: Either on DIN-rail or by fixing to a plate with two screws.

Q3: Can I wire without ferrules?
A: Yes. The table lists cross-sections for both ferruled and non-ferruled conductors.

Q4: What is the difference between 2-bar, 4-bar models?
A: 2-bar models are compact for single-source branching; 4-bar models suit 3P+N layouts;
