Whether you need moulded case circuit breakers (MCCBs) for a workshop distribution board, miniature circuit breakers (MCBs) for a student lab fit-out, or RCBOs for selective protection, we focus on availability, correct ratings and clear invoicing for South African buyers.

Compatibility guidance and accessory bundles
We include accessory suggestions with every quote: correctly sized DIN-rail adapters, busbar kits, auxiliary contacts for remote trip indication, and gland plates for neat panel entry. For retrofits, send panel photos and we’ll suggest breakers that are widely compatible with existing busbars and enclosures to minimise rework.
