Square D 9422TFCF33 - Fused Disconnect Switch

Engineered for industrial and commercial environments, the Square D 9422TFCF33 is a fused disconnect switch that delivers safe, reliable electrical isolation when service or configuration work is needed. Designed to support proper lockout/tagout procedures and to perform a solid disconnection under load, this device stands up to long-term use in demanding settings.

With the trusted Square D lineage, the 9422TFCF33 combines fuse-based overcurrent protection with a robust disconnect mechanism, helping protect personnel and equipment while keeping downtime to a minimum.

Key features and benefits

• Fused isolation for overcurrent protection ensures the circuit is safely isolated and protected from faults, arc energy is contained, and maintenance personnel can work with confidence.
• Lockout/tagout compatibility supports standard safety protocols to prevent accidental re-energizing during service or installation.
• Reliable disconnection under load means current-carrying devices can be safely disengaged without unexpected arcing or damage.
• Rugged, durable construction designed for harsh industrial environments, with components built to endure vibration, dust, and temperature variations.
• Easy integration into existing electrical systems and enclosures, with a compact form factor and familiar Square D interface for quick replacements or upgrades.

Ideal applications

• Maintenance shutdowns for motors, conveyors, pumps, and HVAC equipment in factories and warehouses.
• Service disconnects for panel upgrades or reconfigurations in commercial facilities.
• Emergency isolation at a distribution point to protect workers during electrical work.

Why this fused disconnect stands apart

Unlike non-fused switches, the Square D 9422TFCF33 adds integrated overcurrent protection, reducing the risk of equipment damage during faults and helping ensure a clean, controlled shutdown. The fused design minimizes fault energy and provides a clear path for safe de-energization, which is especially valuable in environments with high inrush or fault currents.

Practical tips for selection and use

• Match the device to your system’s requirements by confirming compatibility with your panel, enclosure, and wiring method.
• Plan for lockout/tagout workflows by pairing the 9422TFCF33 with compatible lockout devices and tags.
• Prepare for maintenance readiness by labeling circuits clearly and maintaining spare fuses or protective elements for quick service.
