A 250A 3-Pole device is commonly used in electrical installations as a switching or protection unit—such as a circuit breaker, isolator, or changeover switch—designed for three-phase power systems.
Configuration:
“3-pole” indicates it controls three live conductors (phases) at the same time. It is mainly used in 3-phase electrical systems, common in industries and large buildings.
•Function:
.Circuit breaker: Protects against overload and short circuit
.Isolator: Safely disconnects power for maintenance
•Changeover switch: Transfers power between sources (e.g., NEPA and generator)
Voltage Rating:
Typically used in systems around 415V (3-phase) in Nigeria.
Build Material:
Made with high-quality copper contacts, strong insulating casing, and arc-extinguishing components for safety.
