Panduit PSL-CBNT Universal Breaker Lockout Device

Panduit PSL-CBNT Universal Circuit Breaker Lockout Device

The Panduit PSL-CBNT delivers tool-free circuit breaker lockout for OSHA 1910.147 energy control compliance. This universal snap-on device secures single-pole and multi-pole breakers in the off position without screwdrivers or adapters, fitting handle heights from 0.30" to 0.60" and thicknesses from 0.16" to 0.35". Built from corrosion-resistant nylon with stainless steel reinforcement, the compact 2.05" × 0.75" form factor handles industrial environments where maintenance crews need reliable lockout on 120V, 277V, and multi-phase breaker panels.

Key Features

• Tool-free snap-on installation — no screwdrivers or allen keys required for lockout engagement
• Universal compatibility — fits single-handle, double-handle, and triple-handle circuit breakers across manufacturers
• Accepts breaker handles 0.30"–0.60" high (7.62–15.24mm) and 0.16"–0.35" thick (4.06–8.89mm)
• Corrosion-resistant nylon body with stainless steel components for harsh industrial and outdoor panel environments
• High-visibility red color meets OSHA standards for immediate lockout identification
• Compact 2.05" × 0.75" footprint fits tight panel spacing without interfering with adjacent breakers
• Accepts standard lockout padlock shackles and hasps for personal energy control locks
• Single-piece construction eliminates loose parts and simplifies field deployment

The PSL-CBNT's snap-fit mechanism grips breaker handles across a wide dimensional range, eliminating the need for brand-specific lockout kits. The device clamps over the breaker handle in the off position, with a rigid nylon body preventing toggle movement. Handle compatibility spans 0.30" to 0.60" in height and 0.16" to 0.35" in thickness, covering square D, cutler-hammer, siemens, GE, and most din-rail breakers found in commercial electrical panels. The lock-accepting slot accommodates shackle diameters up to 7mm, compatible with standard Brady, Master Lock, and American Lock LOTO padlocks. Nylon material provides chemical resistance to oils, solvents, and cleaning agents common in industrial maintenance areas, while stainless steel reinforcement at stress points prevents shackle-area cracking under torque. The injection-molded construction maintains grip integrity across temperature ranges from -40°F to 180°F, suitable for outdoor panels in cold storage facilities and rooftop HVAC disconnects.

Facility maintenance teams deploy the PSL-CBNT during electrical work on lighting circuits, HVAC equipment, conveyor systems, and process machinery supplied through breaker-protected branch circuits. The tool-free installation takes under five seconds per breaker — maintenance techs snap the device over the off-position handle, insert a personal padlock, and proceed with de-energization verification. The universal fit eliminates the inventory complexity of brand-specific lockouts; a single SKU covers the majority of single-pole 120V lighting breakers, two-pole 240V HVAC disconnects, and three-pole 480V motor starters in commercial buildings, warehouses, and light industrial plants. Multi-handle compatibility matters when locking out multi-pole breakers governing three-phase equipment — one PSL-CBNT device can span handles on older breakers with individual toggles per phase. High-visibility red color provides instant recognition during safety audits and allows supervisors to visually confirm lockout status across large panel banks from several feet away. The compact width prevents interference with adjacent breakers in crowded panels, a common issue with oversized lockout devices that block access to neighboring circuits during routine troubleshooting.

Compliance with OSHA 1910.147 — The Control of Hazardous Energy standard — requires positive lockout of energy-isolating devices during servicing and maintenance. The PSL-CBNT meets this requirement for circuit breakers used as disconnect means on 120V and 277V branch circuits, common in commercial lighting and single-phase equipment installations. While the NEC generally prohibits breakers as the sole disconnect for fixed equipment, they're widely used for branch-circuit isolation during lamp ballast replacement, receptacle maintenance, and control wiring work. Red nylon construction resists UV degradation in outdoor-rated panels and maintains structural integrity when exposed to hydraulic fluids, cutting oils, and alkaline cleaners in manufacturing environments — a durability advantage over injection-molded ABS alternatives that crack under solvent exposure or impact in active maintenance areas.
