Description
The CBI 40 A 1P 3 kA Samite Mini Circuit Breaker is a reliable, compact circuit-protection solution — perfect for single-phase circuits that demand higher current capacity. Designed for homes, small commercial installations, or light-industrial setups, this MCB delivers dependable overload and short-circuit protection for heavier-load circuits such as power outlets, sub-circuits, and general-purpose wiring requiring 40 A supply.
With its 40 A rated current and 3 kA breaking capacity, it safeguards wiring and connected devices against dangerous overloads or fault currents — helping to prevent damage and reduce fire risk. The C-curve hydro-magnetic tripping characteristic ensures balanced performance: responsive under fault conditions, yet tolerant of normal surges or startup currents from appliances and equipment, minimizing nuisance trips.
-
