Electrical Circuit Breaker Lockout (CBL16)
This device is a critical component of any Lockout/Tagout (LOTO) program, designed to secure an Electrical Circuit Breaker in the OFF position during maintenance to prevent accidental re-energization.
General Characteristics and Features
- Part Number: CBL16 (Electrical Circuit Breaker Lockout CBL16)
- Core Function: Provides a physical barrier to prevent an electrical circuit breaker switch (toggle) from being moved to the ON position.
- “Lazy Screw” Mechanism: Features a large, ergonomic thumbscrew that allows for quick, tool-free installation. The screw is tightened by hand, making the setup efficient.
- Construction Material: Made from rugged, impact-modified plastic, typically a blend of polypropylene (PP) and nylon (PA).
- Electrical Safety: The non-conductive, dielectric material ensures superior safety by isolating the user from electrical current.
- Padlock Security: Includes a locking hole (typically compatible with 6mm-8mm shackle diameters) to accept a personal safety padlock and LOTO tag, securing the device in place.
- High Visibility: The standard color is bright red, ensuring the lockout device is clearly visible as a warning sign.
- LOTO Compliance: Designed to help organizations meet OSHA 1910.147 and other international safety standards for energy control.
Specific Specification (CBL16)
- Operation: Can be easily operated without any tools (the key benefit of the “Lazy Screw”).
- Temperature Resistance: Capable of withstanding temperatures generally in the range of to .
- Application Focus: Specifically dedicated to certain manufacturer models for a secure fit, often tailored for Schneider circuit breakers EZD below 100A.
- Locking Capacity: Accepts one safety padlock for personal security control.
How to Use (Installation Steps)
- Preparation: Follow the established LOTO procedure, notifying all personnel about the necessary isolation and maintenance work.
- De-energize: Ensure the Electrical Circuit Breaker is switched to the OFF (safe) position.
- Position the CBL16: Place the lockout device over the circuit breaker toggle.
- Secure the Device: Manually turn the “Lazy Screw” clockwise until the device is firmly clamped and secured onto the breaker handle.
- Lockout/Tagout: Insert a unique safety padlock through the designated hole on the device. Attach a corresponding safety tag with the required information (who, when, why).
- Verification: Attempt to move the circuit breaker handle to confirm the device is locked out and the energy source is fully isolated before commencing work.
