Square D VH321BGL Heavy Duty Safety Switch 240V 30A 3-Pole NEMA 1 with Viewing Window

Description

Features

• Rated for 30 Amps at 240V AC, this NEMA 1-rated safety switch is engineered for high-performance motor disconnect and branch circuit protection. Designed to handle the rigorous duty cycles of commercial and industrial environments, it provides a reliable, visible-blade disconnect means that ensures your machinery is completely de-energized during maintenance, preventing accidental startups and equipment damage.
• Factory-installed with a dedicated green-screw ground bar, this "BGL" variant eliminates the need for separate grounding kits, saving you time and money on-site. This built-in feature ensures a low-impedance path to ground, which is critical for clearing electrical faults and maintaining strict compliance with National Electrical Code (NEC) safety standards for permanent installations.
• Constructed with a durable, indoor-rated (NEMA 1) galvannealed steel enclosure and finished with a heat-cured polyester powder coat, this switch is built to resist corrosion and impact. The robust housing protects the internal mechanical components from dust and physical debris, ensuring long-term operational life in indoor commercial spaces like garages, machine shops, and utility rooms.
• Featuring Schneider Electric s legendary spring-loaded operating mechanism, the internal contacts snap open and closed with high speed, regardless of how fast the external handle is moved. This rapid action effectively suppresses arcing and significantly extends the life of the copper contacts, providing a safer, more durable switching solution that reduces the risk of thermal failure during heavy-load operations.
