A main switch circuit breaker is an electrical safety device, installed by an electrical contractor on your electrical switchboard (or meter box), to protect your electrical installation and the connection to Western Power’s network.
The circuit breaker trips off cutting the power when it detects a short circuit or overload, helping to ensure safety by preventing electric shocks, damage to electrical appliances and equipment and possibly resulting power outages. It ensures safe, reliable and equitable access to power for you and your neighbours.
Timelec’s main switch is of high quality and widely used in residual building, pv system and commmercial electricity distribution system.
