Suggested pairing: The multifunctional circuit breaker locking device should be used with insulated padlocks and safety signage to achieve energy isolation, equipment locking, and prevention of misoperation. Tool locking: Fastening screws allow manual locking without tools, making operation more convenient. The screw mouth diameter is larger than before, providing an easier and more laborsaving tightening experience. Safety lock for small circuit breakers: Designed for safety and security, this lockout has a robust construction that resists deformation, offering a reliable electrical safety solution for workers. Material and durability: The lock body is made of reinforced nylon PA with erosion resistance, electrical insulation, and a wide operating temperature range of 50 C to +177 C. It remains resistant to deformation and uses copper screws, suitable for a variety of operating environments. Applications and use scenarios: Industrial maintenance: Lock out small circuit breakers during machine servicing in manufacturing facilities to ensure energy is isolated and operations are prevented from reenergizing accidentally. Building management and electrical servicing: Use in commercial or facility electrical panels to comply with lockouttagout procedures and protect maintenance personnel. Renewable energy and automation systems: Secure lockout for circuit breakers in solar, wind, or process automation installations where reliable electrical safety is required in diverse environments.
