Why it matters

When maintenance or repair work is required, you need a switch you can trust to isolate circuits reliably, even under load. The HF221NR delivers deliberate, dependable disconnection, reducing the risk of unexpected energization and facilitating safe lockout/tagout procedures.

Key benefits

• Durable, industrial-grade construction: Built to endure the demands of busy facilities and harsh environments, with long-term durability that minimizes replacement and downtime.
• Secure, two-pole isolation: The two-pole design ensures both conductors are isolated simultaneously for complete circuit de-energization.
• 30A capacity for common loads: Suitable for many motor feeders and control circuits without oversizing equipment.
• Safe maintenance with LOTO compatibility: Designed to support proper lockout/tagout workflows, helping meet safety standards during servicing.
• Reliable disconnection under load: Engineered to interrupt power cleanly even when circuits are energized, reducing fault conditions.

Ideal use cases

• Motor control circuits and feeder lines in manufacturing, packaging, and processing facilities
• Service disconnects in commercial buildings, workshops, and industrial spaces
• Temporary isolation points during installation, testing, or repair tasks
