Siemens HF221N - 30A, 240V, 2-Pole, Safety Switch

Siemens HF221N stands as a rugged, high-performance safety switch engineered for industrial and commercial environments that demand safe, reliable electrical isolation. With a 30A amperage rating and 240V operation across 2 poles, this device delivers clean, dependable disconnection when service is required, even under load. Built to support proper lockout/tagout procedures, the HF221N helps teams maintain control of energized equipment and protect workers during maintenance and inspections.

Two-pole design ensures both hot conductors are isolated, providing full discharge of power and reducing the risk of accidental re-energization. This is especially valuable in motor control centers, conveyors, and other machinery where safe shutdown is non-negotiable.

Why choose the HF221N? It’s engineered for long-term durability in demanding settings, balancing solid mechanical performance with consistent electrical isolation. The result is fewer surprises during servicing, less downtime, and a safer work environment for operators and maintenance staff alike.
