Why choose the Square D DU222RB?

The non-fusible design ensures straightforward, maintenance-friendly electrical isolation without relying on fuse elements that can wear or fail. It provides quick, confident disconnection under load, which minimizes downtime and reduces risk during servicing. The 2-pole configuration isolates both conductors, helping protect personnel and equipment during maintenance, repairs, or system changes.

Key benefits and use cases

• Safe lockout/tagout compatibility: Integrates with standard safety procedures to prevent accidental re-energization during servicing.
• Industrial and commercial readiness: Built to withstand demanding environments where reliable isolation is critical.
• Long-term durability: Designed for repeated operation and extended service life in busy electrical rooms or panel enclosures.
• Immediate disconnection under load: Reduces risk of arcing and improves worker safety during switching.
• Two-pole isolation: Safely disconnects both hot lines for full circuit isolation.

Ideal applications

Any facility needing dependable circuit isolation without fuses—manufacturing floors, distribution panels, utility rooms, or commercial spaces with routine maintenance and energy management needs.

Practical tips

• Pair with established lockout devices and tags to meet OSHA or local safety standards.
• Schedule periodic inspections of the disconnect switch to ensure smooth operation and clear labeling.
• Store spare fuses separately; for non-fusible switches, focus on mechanical reliability and wiring integrity during inspections.

Equip your electrical safety toolkit with the Square D DU222RB to ensure rapid, reliable isolation and safer maintenance cycles.
