MCB Lockout Device
BD-D02
BD-D02 is a push-button MCB lockout device for instant, tool-free LOTO compliance. It secures most European and Asian miniature circuit breakers in the OFF position with one press, preventing accidental re-energization during maintenance.
- Simply press the button to extend the pins, insert into the circuit breaker, release and lock. Done in seconds without any additional tools.
- Engineered to fit the vast majority of miniature circuit breakers used across Europe and Asia, supporting pin hole spacing ≤ 12mm.
- Features a Ø 7.0mm lock hole, compatible with standard industrial insulated safety padlocks (shackle diameter ≤ 7mm), ensuring a verified lockout state.
- Pin-out design with corrosion-resistant 304 stainless steel pins ensures long-term durability in demanding industrial environments.
- Dimensions: 41mm × 24mm × 24mm. The black-and-red color combination provides immediate visual identification of a locked-out breaker.
- Impact-resistant, electrically insulating PA nylon body withstands workshop conditions while maintaining dielectric safety.

FAQs
1What is the BD-D02 MCB Lockout Device used for?
The BD-D02 is a LOTO (Lockout-Tagout) device used to lock miniature circuit breakers (MCBs) in the OFF position during maintenance or repair, preventing accidental re-energization. It is used in electrical panel servicing, machine maintenance, and energy isolation procedures..
2How does the pin-in design work?
The BD-D02 uses inward-facing 304 stainless steel pins. When the button is pressed, the pins extend and insert into the MCB's locking holes (pitch ≤ 12mm), securing the device firmly to the breaker without any tools.
3What is the write-on warning tag for?
The built-in warning label allows the technician to write their name, contact number, date, and work order reference directly on the device. This provides on-device personnel identification required by OSHA 29 CFR 1910.147 and EN ISO 50110 LOTO standards — no separate tag needed.
4What padlock is compatible with the BD-D02?
Any professional industrial insulated safety padlock with a shackle diameter ≤ 7mm. The BD-D02's lock hole diameter is 7.0mm.
5Which circuit breakers does the BD-D02 fit?
It fits most European and Asian miniature circuit breakers (MCBs) with a pin hole spacing ≤ 12mm, including standard single-pole and multi-pole breakers.
6How is BD-D02 different from BD-D01?
The BD-D02 has inward-facing pins (Pin-In) versus BD-D01's outward-facing pins (Pin-Out), and adds a built-in write-on warning tag for LOTO documentation. Both share the same dimensions, materials, and compatibility range.
