WGL Series Industrial Load Break Disconnect Switches

Introduction
In today’s diverse industrial and commercial electrical environments, no single switch can meet all isolation requirements. The WGL Series Industrial Load Break Disconnect Switches addresses this challenge with a comprehensive, scalable product family designed to provide safe, reliable manual isolation across the full spectrum of power distribution applications. From compact 125A branch circuit isolators to heavy-duty 1600A main distribution switches, the WGL Series offers engineered solutions that balance performance, safety, and value for system designers, panel builders, and facility managers worldwide.

Series-Wide Engineering Excellence

1. Scalable Performance Across the Range
Feature: The series spans current ratings from 125A to 1600A, with each model optimized for its specific duty. Lower-current models emphasize compactness and cost-effectiveness, while higher-current units focus on robust construction and maximum safety features.
Benefit: Provides a single-source solution for all isolation needs within a facility, simplifying procurement, installation, and maintenance while ensuring consistent quality and performance across all protection points.

2. Configurable for Any System Architecture
Feature: Available in both 3-pole (L1-L2-L3) and 4-pole (L1-L2-L3-N) configurations. The 4-pole versions provide complete isolation including the neutral conductor, essential for systems with sensitive electronics or where full circuit separation is required for safety.
Benefit: Offers precise application matching, allowing engineers to select exactly the right switch for each specific circuit requirement, whether it’s a simple motor disconnect or a critical main power isolator in a three-phase four-wire system.

3. Consistent Safety Philosophy
Feature: Every model in the WGL Series incorporates the fundamental safety principle of visible contact separation. All switches provide clear “ON” and “OFF” indication, with a definitive air gap visible when in the open position. Standard padlock provisions enable secure Lockout/Tagout (LOTO) procedures.
Benefit: Ensures uniform safety compliance across all isolation points in your facility, protecting maintenance personnel and meeting international electrical safety standards consistently.

4. Engineered for Reliability and Ease of Use
Feature: The series employs a graduated design approach where construction materials and mechanisms are optimized for each current rating. Lower amperage models feature efficient cage-clamp terminals, while higher ratings utilize heavy-duty busbar connections. All models offer intuitive operation and clear status indication.
Benefit: Delivers appropriate performance at every level—avoiding over-engineering in smaller applications while providing uncompromising durability where it matters most in high-current scenarios.

Technical Range Overview

Application Spectrum

• Light Commercial & HVAC: Smaller models (125A-250A) for branch circuits, HVAC units, and commercial equipment isolation.
