CBI 15A 1P 3kA Circuit Breaker

The CBI 15 A 1P 3 kA Samite Mini Circuit Breaker is a compact, reliable circuit protection device — designed for safe, everyday electrical circuits in homes and small-scale commercial installations. Its single-pole configuration is ideal for lighting circuits, small socket outlets, and other low- load applications needing dependable over-current protection.

With a 15 A rated current and 3 kA breaking capacity, this breaker effectively protects wiring and connected devices from overloads and short-circuit faults, reducing the risk of damage or fire. The hydraulic-magnetic C-curve trip characteristic ensures responsive protection while tolerating normal surges or startup currents (for example from appliances or lighting loads), minimizing nuisance trips under normal use.

• Model / Series: QA-1(13) Mini-Rail / Samite-mount 1-pole breaker

• Type: Miniature Circuit Breaker (MCB), Single-Pole (1P)

• Rated Current (In): 15 Amps — suitable for low- to moderate-load circuits (lighting, small socket circuits, small appliances)

• Breaking Capacity (Icu / Ics): 3 kA — safely interrupts overloads or short-circuit fault currents up to 3000 A

• Voltage Rating: 240 V AC (single-phase domestic / commercial supply) — standard for residential and light-commercial installations.

• Tripping Mechanism / Characteristic: Hydraulic-magnetic with “C-curve” (standard) — provides overload and short-circuit protection while tolerating normal inrush/start-up currents from devices.

• Mounting / Form Factor: Samite / Mini-rail — 13 mm module width; ultra-compact, designed to fit in standard Samite / mini-rail distribution boards / consumer units.

• Poles / Configuration: Single-pole (1P) — protects one live conductor; suitable for single-phase circuits (lighting, sockets, small power circuits).

• Protection Provided: Overload protection & short-circuit protection — safeguards wiring and connected devices from electrical faults, surges or overloads.

• Physical Dimensions / Build: Compact plastic housing, 13 mm width module — minimal space consumption; typical Mini-Rail mounting height/width as per CBI specification.

• Standards / Compliance: Compliant with relevant standards applicable to low-voltage MCBs (IEC/SANS / manufacturer spec for Samite-rail breakers)

• Typical Applications: Domestic homes, apartments, small offices — lighting circuits, socket circuits, small-appliance power circuits, sub-circuits requiring 15 A protection; ideal for retrofit or new install in Samite-rail boards.
