Siemens HF361 - 30A, 600V, 3-Pole, Heavy Duty Fused Safety Switch

Siemens HF361 is a purpose-built Heavy Duty Fused Safety Switch engineered for industrial and commercial environments where safe electrical isolation is non-negotiable. With a 30A amperage rating and a 600V capacity, this 3-pole configuration delivers reliable disconnection under load, empowering maintenance teams to lock out and tag out circuits with confidence and speed.

Designed for three-phase systems, the HF361 ensures complete isolation of each phase, reducing the risk of arc flash and equipment damage during servicing. Its robust construction is ready to withstand the harsh realities of busy facilities—vibrations, temperature fluctuations, and the daily wear that comes with heavy use—so you don’t have to worry about unexpected downtime.

What makes the HF361 stand out

• Precise 30A protection for typical industrial load centers and motor circuits, providing targeted overcurrent interruption without unnecessary power loss.
• 600V rated performance suitable for a wide range of commercial and industrial three-phase applications.
• 3-Pole design delivers full three-phase isolation, improving safety and fault containment in complex electrical layouts.
• Built for lockout/tagout readiness to support compliant maintenance procedures and enhanced personnel safety.
• Durable, long-term reliability engineered to endure repetitive switching and demanding environments, reducing maintenance cycles and total cost of ownership.

Ideal for

• Industrial motor control panels and equipment disconnects
• Commercial facilities with three-phase power infrastructure
• Maintenance shutdowns where safe, verifiable isolation is required
• Upgrade projects that demand robust, programmable safety disconnects

Usage scenarios and practical benefits

• During routine maintenance, technicians can lock out power to prevent accidental energization, protecting personnel and equipment.
• In manufacturing lines, the HF361 provides quick, dependable disconnection to minimize downtime while performing inspections or repairs on energized systems.
• In facilities with mixed-load environments, the 3-pole, 600V capability supports safe isolation across multiple three-phase circuits from a single point of control.
