MCB Lockout Device – Model LB05
The MCB Lockout Device (Model LB05) is a compact and reliable safety solution designed to secure miniature circuit breakers (MCB) during electrical maintenance and inspection work. As a key component of a Lockout Tagout (LOTO) system, this device prevents accidental re-energization of electrical circuits, ensuring worker safety and regulatory compliance.
Manufactured from high-strength insulated engineering plastic, the LB05 is lightweight yet durable, making it ideal for frequent use in electrical panels and distribution boards. Its adjustable screw-clamp design allows it to firmly lock onto MCB toggle switches, providing a stable and secure fit across common breaker sizes.
The tool-free tightening knob enables quick installation and removal, improving work efficiency during maintenance tasks. A 7mm padlock hole supports standard safety padlocks, allowing authorized personnel to apply personal locks and clearly control energy isolation. The bright red safety color offers immediate visual warning, reinforcing safety awareness in electrical environments.
This MCB lockout is widely used in commercial buildings, factories, control panels, and industrial electrical systems, helping organizations reduce electrical hazards, prevent human error, and meet OSHA and international LOTO standards.
