| Handle Lock | Prevents accidental operation | Eaton BR breakers | Metal | Industrial systems |
What is a Breaker Handle Tie?
A breaker handle tie is a safety accessory that connects the handles of two circuit breakers. This ensures that both breakers operate together, which is particularly important in multi-phase systems. When one breaker trips, the handle tie causes the other breaker to trip as well, preventing potential overloads and enhancing safety.
Types of Breaker Handle Ties
Handle Ties
Handle ties are primarily designed for single-pole breakers. They are easy to install and can be used to connect two breakers, ensuring they trip together. These ties are commonly used in residential circuits where dual breakers are employed, such as in 120V circuits.
Common Trip Ties
Common trip ties are specifically designed for two-pole breakers, often used in 240V circuits. When one breaker trips, the common trip tie ensures that the second breaker also trips, providing an additional safety net. This is crucial in commercial applications where equipment may draw significant power.
Mini Circuit Breaker Accessories
Mini circuit breaker accessories, like the HOM1HT, offer versatility in smaller residential settings. These accessories allow for customization while still maintaining safety standards. They are generally used in Homeline breakers and are ideal for compact installations.
Handle Locks
Handle locks are designed to prevent the accidental operation of breakers. They are widely used in industrial settings where equipment must remain operational unless intentionally shut down. The handle lock provides a physical barrier, ensuring that the breaker cannot be reset without authorization.
Applications of Breaker Handle Ties
Breaker handle ties find applications across various sectors—residential, commercial, and industrial.
Residential Use
In residential settings, handle ties are commonly used to ensure safety during electrical overloads. They help prevent potential hazards by ensuring that circuits operate in unison, particularly in setups where multiple breakers are needed.
Commercial Use
In commercial applications, common trip ties play a crucial role in managing larger electrical loads. They ensure that if one circuit experiences issues, the entire system is safeguarded from overloading, which could lead to equipment failure or fire hazards.
Industrial Use
For industrial systems, handle locks provide an additional layer of security. These locks ensure that only authorized personnel can operate or reset breakers, thereby reducing the risk of accidents and maintaining operational efficiency.
