Reliable Breaker Protection
The MCB Universal Lockout transforms safety procedures by offering a truly versatile solution for isolating circuit breakers. Its universal fit and durable design ensure that maintenance teams can work confidently, knowing each breaker remains securely de-energised.
With a compact, user-friendly form factor, it minimises downtime and streamlines every lockout process. Plus, sourcing from The Workplace Depot means you benefit from the lowest prices and fastest delivery, keeping budgets in check and projects on schedule.
Universal Compatibility
Its design accommodates both single- and multi-pole miniature circuit breakers from all leading manufacturers, eliminating the need for multiple specialised lockouts. This broad compatibility reduces inventory complexity and ensures the right tool is always at hand.
By fitting handles up to 7.9 mm wide, it slips into virtually any panel layout without modification. Whether you’re servicing an office distribution board or a heavy-duty warehouse switchgear, one device covers every scenario.


Tool-Lock Mechanism
A simple set-screw action with a standard screwdriver secures the device in seconds, so teams spend less time preparing and more time servicing. There’s no reliance on bespoke tools or adapters, making every lockdown straightforward and hassle-free.
This streamlined approach cuts installation time and helps maintain smooth workflows, particularly in high-volume maintenance schedules. The familiar screwdriver interface also reduces training needs for new staff.

Padlock Ready
A built-in aperture accepts safety padlocks with up to an 8 mm shackle, giving clear visual confirmation that a breaker is locked out. This single-padlock capacity simplifies procedures and ensures each isolation point is unmistakably secured.
By standardising on one padlock per lockout device, teams avoid confusion over multiple lock types and maintain consistency across sites. The result is a safer environment and a more efficient maintenance routine.


Reinforced Nylon Construction
Its reinforced nylon PA construction delivers exceptional resistance to wear, impact and harsh chemicals, ensuring the device withstands repeated use in demanding environments. This robust build maintains its integrity under heavy handling, minimising the need for replacements and repairs.
By combining high-strength materials with precise moulding, the Lockout Equipment retains strength without adding bulk. Maintenance teams benefit from consistent performance, even when subjected to industrial cleaning agents or mechanical knocks.
Complete Electrical Isolation
The fully non-conductive design provides reliable electrical isolation, safeguarding personnel during installation and routine maintenance. Technicians can work confidently, knowing that the risk of accidental contact with live circuits is greatly reduced.
Integrating this feature into the MCB Universal Lockout streamlines safety procedures, eliminating the need for additional insulating barriers. Clear separation from live components enhances peace of mind across every lockout operation.


Slim Panel Fit
With a low-bulk profile measuring just 25 (H) x 45 (W) x 10 (D) mm, it slots neatly into crowded breaker panels without obstructing neighbouring components. This space-saving form factor ensures tight panel layouts remain accessible and organised.
The compact dimensions also simplify storage and transport, so teams can carry multiple units without added weight. Whether servicing dense industrial switchboards or compact office distribution boards, it adapts to any configuration.
High-Visibility Finish
The bright safety yellow finish offers instant visual confirmation of a secured breaker, reducing the chance of accidental reactivation. This vivid colour also aids quick identification during routine inspections and emergency shutdowns.
By applying a consistent, attention-grabbing hue to each lockout device, maintenance workflows become more intuitive. Teams can scan panels at a glance, ensuring that every isolated circuit remains clearly flagged until work is complete.
