Shipping

The 3/4 - Disconnect Switch, model 4-Mar, is engineered for safe electrical isolation in the most demanding industrial and commercial environments. It delivers dependable disconnection under load while supporting robust lockout/tagout procedures, helping teams maintain safety and uptime across operations.

Designed for safety and reliability

  • Lockout/Tagout readiness: compatible with standard lockout/tagout practices to prevent accidental energization during maintenance.
  • Under-load disconnection: reliable switching even when circuits are live, reducing risk and downtime.
  • Long-term durability: built to endure frequent operation and challenging facility conditions, preserving performance over years of service.
  • Industrial and commercial readiness: specifically designed to meet the needs of plant floors, service panels, and facility operations.

What makes 4-Mar unique

Ideal for

  • Maintenance teams performing routine or emergency electrical servicing

  • Electrical contractors installing or upgrading control systems

Practical use cases

Use the 3/4 - Disconnect Switch during panel maintenance, equipment servicing, or any task that requires safe, intentional isolation of a live circuit. It provides a clear, unambiguous means to disconnect power and verify isolation with appropriate testing equipment before work resumes.

Maintenance and care

Keep your system operating safely with regular visual inspections for signs of wear, ensuring lockout devices and tags remain intact, and performing periodic functional checks to verify clean engagement under load.
