CLAMP CIRCUIT LOCK
• Full Shield Clamp Circuit Breaker Lock is suitable for a variety of medium-sized built-i
Product Overview
The Full Shield Clamp Circuit Breaker Lock is a robust Lockout/Tagout (LOTO) device engineered for medium-sized built-in tripping molded case circuit breakers (MCCBs). Manufactured from high-grade polypropylene (PP) and high-strength modified nylon (PA), it delivers lasting durability in demanding industrial environments. Its innovative blade design and shaped-screw fixing system provide a secure, rattle-free lockout that safeguards personnel during maintenance and servicing operations.
Key Features
- Compatible with a wide range of medium-sized built-in tripping MCCBs
- Accommodates both single-pole and internal-stroke multi-pole circuit breakers
- Optional snap and clamp locking mechanisms for flexible installation
- Constructed from strong polypropylene (PP) and high-strength modified nylon (PA)
- New blade design requires minimal force on profiled screws while maintaining a tight heel bond
- Shaped screws secure the lock body to the switch handle; cover fastens over screws to prevent loosening
- Removable splint included to further expand the range of compatible breakers
- Base clamps to the bottom of the lock body quickly and easily
- Long sliding splint ensures a positive, secure lockout of the circuit breaker
- Accepts padlocks with a maximum shackle diameter of 7 mm

Product Benefits
The adjustable clamp design and included removable splint allow the lock to fit a wide variety of medium-sized MCCBs—both single-pole and multi-pole—reducing the need to stock multiple lockout devices and lowering overall safety inventory costs.
Profiled screws anchor the lock body firmly to the circuit breaker handle, and the snap-on cover prevents the screws from backing out. This double-retention system ensures the device cannot be inadvertently dislodged during busy maintenance activities.
Polypropylene and high-strength modified nylon are resistant to impact, chemicals, and UV exposure, making this lock reliable in the harsh ambient conditions typical of Saudi Arabian industrial sites, including high temperatures and dusty atmospheres.
The new blade geometry reduces the torque needed on profiled screws without compromising grip, allowing technicians to install and remove the lock quickly—minimising downtime while maintaining full safety compliance.
Acceptance of padlocks up to 7 mm shackle diameter means multiple tradespeople can each attach their own personal padlock during group lockout procedures, fully satisfying LOTO best-practice requirements.
