The CBI 63 A 3 kA Samite Earth-Leakage Device is a high-capacity, high-sensitivity residual-current breaker designed to protect electrical installations from earth-fault leakage, reducing risk of electric shock or fire. With its 63 A current rating, it’s suitable for main supply lines, sub-mains, or high-load circuits, making it ideal for both domestic and light-commercial environments.

Featuring a 30 mA leakage sensitivity, this unit quickly detects even small leakage currents — such as those caused by insulation degradation, moisture ingress, or stray fault currents — and trips the circuit to prevent danger. Its 3 kA breaking capacity ensures that in the event of a fault or short circuit, the device interrupts the current safely, protecting wiring, appliances, and the installation.

• Rated Current (In): 63 Amps — suitable for heavy-duty single-phase supply circuits, sub-mains or main feeds.

• Leakage Sensitivity (IΔn): 30 mA — trips when residual/earth-fault current exceeds 30 mA.

• Breaking / Fault-Current Capacity (Icu / Ics): 3 kA — able to safely interrupt fault or short-circuit currents up to 3000 A.

• Voltage Rating: ~220–240 V AC (single-phase) for 1P+N versions, or 415 V (3P+N) for three-phase variants (depending on model) — suitable for typical residential, commercial or light-industrial installations.

• Poles / Configuration: 1 Pole + Neutral (1P+N) for single-phase; or 3 Pole + Neutral (3P+N) for three-phase versions, depending on model.

• Mounting / Form Factor: Samite / Mini-rail mount (compact width module, typically 26 mm) — designed for standard Samite-rail or mini-rail distribution boards and consumer units.

• Trip Mechanism: Hydraulic-magnetic / residual-current mechanism — detects imbalance between live and neutral (earth / leakage current) and trips within required time.

• Standards / Safety Compliance: Compliant with relevant safety standards for earth-leakage devices (e.g., standard leakage sensitivity 30 mA, meets VC 8035 / IEC/EN 60947-2 requirements for RCDs / ELBs).

• Typical Applications: Residential or commercial circuit protection requiring earth-leakage / residual-current protection — e.g. main incoming supply, sub-mains, heavy-load socket banks, geyser circuits, workshops, or any circuit where protection from earth-fault/leakage and electric shock risk is required.
