Siemens 3LD2504-0TK53 - 63A, 400V, 3-Pole, Disconnect Switch

< p>Introducing the Siemens 3LD2504-0TK53, a purpose-built disconnect switch engineered for safe, reliable electrical isolation in demanding industrial and commercial environments. With a 63A rating at 400V across three poles, this switch provides dependable disconnection when service or maintenance is required, while supporting essential lockout/tagout procedures to keep teams safe.

Why engineers choose the Siemens 3LD2504-0TK53

• Three-pole isolation ensures all phases are interrupted simultaneously, eliminating partial energization and reducing the risk during maintenance or testing.
• 63A, 400V performance is tailored for standard three‑phase distribution and equipment control tasks, delivering consistent, predictable operation in everyday workflows.
• Safe disconnection under load designed to provide reliable isolation even when circuits are energized, supporting timely maintenance without compromising safety.
• Lockout/Tagout readiness built to integrate with your safety protocols, helping teams verify a de-energized state before work begins and stay compliant with policy requirements.
• Durable, industrial-grade design ready for continuous duty in busy environments, delivering long-term reliability that reduce downtime and replacement costs.

Practical use cases

• Powering down manufacturing lines for preventive maintenance or tool changes without risking residual energy in any phase.
• Isolating equipment in control cabinets, motor control centers, or distribution panels to simplify safe servicing.
• HVAC or process cooling systems where reliable three-phase isolation is required during routine inspections or repairs.

What this means for you

• Enhanced maintenance safety through robust lockout/tagout compatibility, ensuring workers can confidently secure a de-energized system.
• Clear, reliable disconnection across all phases minimizes surprises during servicing and reduces the chance of arc flash or unexpected re-energization.
• A trusted Siemens solution backed by decades of engineering excellence, designed to integrate smoothly into existing electrical infrastructure.

Engineers, technicians, and procurement teams who manage three-phase systems will appreciate the clarity of the 3LD2504-0TK53—a dedicated disconnect switch that prioritizes safety, reliability, and clear operational outcomes in daily electrical isolation tasks.
