Square D H221DS - 30A, 240V, 2-Pole, Safety Switch

The Square D H221DS Safety Switch is built for industrial and commercial environments where safe electrical isolation is non-negotiable. With a 30A rating at 240V and a 2-pole design, this switch delivers dependable, clear disconnection under load, supporting efficient maintenance and safe operation of powered equipment.

Why the Square D H221DS stands out

• Two-pole isolation seals off both hot lines, ensuring full de-energization and preventing backfeed during servicing.
• 30A at 240V tailored for motor controllers, pumps, conveyors, and other medium-duty equipment common in busy facilities.
• Lockout/Tagout readiness designed to integrate with standard safety procedures, helping crews lock and tag the circuit during maintenance.
• Reliable disconnection under load capable of safely interrupting circuits that may be energized from upstream sources, reducing risk during servicing.
• Durable, industrial-grade construction engineered to endure daily use and the demanding conditions of modern facilities.

Ideal use cases

• Shutting down motors, pumps, fans, and conveyor systems for maintenance or reconfiguration.
• Isolation tasks in control panels and electrical enclosures where accidental energization must be prevented.
• Routine servicing and preventive maintenance that require a clear, verifiable disconnect.
• Equipment upgrades or testing sequences that demand a safe, controlled power-off.

Who benefits

• Electrical contractors and facility maintenance teams seeking dependable safety isolation.
• Plant operators implementing strict lockout/tagout and safety protocols.
• Systems integrators designing reliable power-distribution and equipment control solutions.

Installation is straightforward within standard electrical enclosures used for 240V circuits. For optimal safety, pair the Square D H221DS with proper lockout devices and tagging to reinforce compliance during maintenance and changes in operation.
