Siemens 4/4X - 30A, 3-Pole, Disconnect Switch

Siemens 4/4X 30A 3-Pole Disconnect Switch delivers dependable electrical isolation for industrial and commercial environments where safety and reliability matter. Built to support lockout/tagout procedures, this disconnect switch ensures safe maintenance and predictable disconnection even when circuits are under load.

Designed for robust performance, the 4/4X handles three-phase power with a 30-amp rating, making it a practical choice for motor control, distribution panels, and equipment isolation in factories, warehouses, and large facilities. Its three-pole design ensures all hot conductors are opened simultaneously, reducing the risk of partial energization.

Key advantages and use cases:

• Three-pole, 30A configuration supports standard 3-phase systems and reliable switching for common industrial loads.
• Lockout/tagout compatible supports compliance with safety protocols during maintenance and service outages.
• Reliable under-load disconnection provides a safe, immediate isolation even with energized equipment, helping prevent accidental re-energization.
• Durable, purpose-built design from Siemens for long-term service in demanding environments, reducing maintenance costs and downtime.
• Seamless integration with Siemens electrical panels and switchgear ensures consistent operation across your system.

Who benefits? This disconnect switch is ideal for facilities managers, electricians, and engineers responsible for protecting personnel and equipment during servicing. It’s well-suited for motor starters, panel boards, distribution boards, and other industrial loads that require quick, safe isolation without compromising on reliability.

Installation and care tips: ensure the switch is properly mounted in a suitable enclosure, verify the load current doesn't exceed 30A, and perform routine inspections of connections and operating mechanism to maintain smooth operation. Always follow your facility's lockout/tagout procedures and training when isolating power.
