HD323SN - 100A, 240V, Fused Disconnect Switch

The HD323SN is a high-performance fused disconnect switch designed for reliable electrical isolation in demanding industrial and commercial environments. With a 100A rating at 240V, this switch delivers a decisive disconnect under load, enabling safe maintenance and quick, intentional power-downs. Its integrated fuse protection adds an essential layer of circuit safety, while compatibility with lockout/tagout procedures helps keep personnel safe during servicing and commissioning.

Why choose the HD323SN?

• Clear, lockout-ready disconnect point: Establishes a clearly identifiable isolation location for servicing, reducing the risk of accidental re-energization.
• 100A at 240V with fused protection: Combines reliable current handling with built-in protection to guard circuits and assist fault isolation.
• Durable, industrial-ready design: Built to perform consistently in demanding environments, supporting long-term reliability.
• Supports lockout/tagout procedures: Facilitates safe work practices and compliance during maintenance and testing.

Ideal applications

Use the HD323SN to create safe isolation points in electrical service panels, equipment enclosures, and large electrical assemblies. It’s well-suited for manufacturing lines, HVAC and pump stations, electrical rooms, and other setups where a reliable, under-load disconnection is essential for safety and uptime.

Safety and uptime benefits

• Fast, under-load disconnection minimizes arc energy and equipment damage during maintenance or emergency shutdowns.
• Simple integration with existing infrastructure thanks to a standard 240V operation and 100A capacity.
• Long-term reliability reduces downtime and replacement costs, supporting consistent performance over years of service.
