Learn more by watching our SICAME MCB3/4HAE | Mains Box Three Phase video.
The Sicame MCB3/4HAE is a three-phase mains connection box designed for consumer mains protection and service cable termination. It accommodates 6 to 35mm² cable and contains four HSC (House Service Connector) units providing fully sealed bi-metallic connections. The MCB3/4HAE is Queensland-approved and complies with standard electrical installation practices for domestic and commercial properties requiring three-phase supply.
Three-phase mains connection requires reliable, weatherproof termination at the consumer end. The MCB3/4HAE addresses this by combining fully insulated construction with a metal-to-metal sealing system (bi-metallic connection between copper consumer mains and aluminium or copper service cables). The base accommodates rear entry of consumer mains, eliminating exposure of PVC sheathing to UV degradation. Licensed electricians performing three-phase service connections value the MCB3/4HAE for its build quality and proven reliability on domestic upgrades and new multi-phase installations.
The MCB3/4HAE incorporates design features that support fast, repeatable installation. All connections use 13mm across-flats hexagon sockets for standardised bolt tightening. The plug-in HSC connector system allows simple removal and replacement of individual service connections without disturbing the box assembly. The cover design permits easy exit of bonding tail cable (HSC435/1 series), a requirement in modern installations. Heavy-duty UV-stabilised polyamide construction and IP66 rating keep the internal connection point protected from weather and salt spray in exposed environments.
The MCB3/4HAE is not suitable for single-phase installations. It is designed exclusively for three-phase (3P+N) supply and should not be used on single-phase consumer mains (1P+N). Installation must be performed by a licensed electrician in accordance with the Electrical Safety Act and AS/NZS 3000 standards.
