Square D H224N - 200A, 240V, 2-Pole, Fused Disconnect Switch

The Square D H224N fused disconnect switch delivers dependable electrical isolation for demanding industrial and commercial environments. Rated for 200 A at 240 V and configured as a 2-pole device, it provides a decisive, lockable break in the circuit when service, maintenance, or an emergency shutdown is required. Built to endure long-term use under load, this disconnect switch offers durable protection that helps safeguard personnel and equipment.

Key benefits that set the H224N apart

• Robust fused protection – Fuses provide rapid fault isolation, helping prevent damage to downstream equipment and reducing the risk of arc flash during maintenance.
• Two-pole isolation – With two hot legs completely disconnected, the load is safely isolated from power sources on both lines.
• Lockout/Tagout readiness – Designed to integrate with standard lockout/tagout procedures, supporting safe and compliant maintenance practices.
• High durability – Constructed for steady performance in demanding environments, delivering reliable operation over time even in busy electrical rooms.
• Service-friendly design – Replaceable fuses and straightforward disconnection make maintenance downtime predictable and manageable.

Ideal applications and use cases

• Large motor feeders and conveyor systems in manufacturing and industrial facilities
• HVAC power distribution and mechanical equipment control where safe isolation is critical
• Electrical panels, switchboards, and service entrances that require reliable on/off with fuse protection
• Maintenance shutdowns and routine servicing where equipment must be safely de-energized
