Square D H221N - 30A, 2-Pole, Disconnect Switch

The Square D H221N is a purpose-built 30A, 2-pole disconnect switch designed for rugged industrial and commercial environments where safe electrical isolation is non-negotiable. Engineered to support proper lockout/tagout procedures, this isolator ensures dependable disconnection under load, contributing to safer maintenance and longer equipment life.

Why choose the H221N for your electrical safety and reliability needs

• 20-Ampere-level performance with dual-pole isolation: A 30A rating across two poles provides simultaneous disconnection of both live conductors, reducing the risk of partial energization during service work.
• Lockout/Tagout readiness: Designed to integrate smoothly with standard LOTO practices, helping facilities meet safety protocols and regulatory expectations with confidence.
• Durable, long-term durability: Built to withstand demanding environments, delivering consistent performance and reduced maintenance over time.
• Clear reliability under load: Engineered to disconnect reliably when circuits are energized, supporting safer shutdowns during repairs or inspections.

Ideal use cases

• Motor and equipment circuits in manufacturing floors where quick, safe isolation is required during routine maintenance.
• Service panels and electrical rooms in commercial facilities that demand clear, redundant disconnection points.
• OEM installations where a compact, dependable disconnect switch is needed to meet safety standards and simplify lockout/tagout workflows.

What this means for you

With the Square D H221N, technicians gain a straightforward, trustworthy means of isolating power, reducing downtime and the risk of accidental re-energization. Its two-pole design ensures both hot lines are shut off together, providing a safer working platform for electricians, maintenance crews, and facilities managers alike.
