Description
The Onesto 40A 1P 3kA Mini Circuit Breaker is designed to provide reliable protection for your electrical circuits against overloads and short circuits. Ideal for residential, light commercial, and higher-load applications, this single-pole breaker is perfect for heavier socket circuits, larger appliances, lighting, and general-purpose power circuits.
With a rated current of 40 A and a breaking capacity of 3 kA, it safely interrupts overloads and short-circuit events, protecting wiring and connected devices from damage. Its DIN-rail mounting allows for quick and secure installation in standard distribution boards, and the manual reset feature makes restoring power simple after a trip. Built to meet international safety standards, the Onesto 40A MCB ensures consistent performance and peace of mind.
-
Type: Miniature Circuit Breaker (MCB), Single‑Pole (1P)
-
Rated Current (In): 40 Amps — suitable for medium‑to‑higher‑load single‑phase circuits (e.g. heavier power sockets, larger appliances, light‑industrial circuits).
-
Breaking Capacity (Icu / Ics): 3 kA — designed to safely interrupt overload or short‑circuit current up to 3000 A.
-
Rated Operational Voltage (Ue): 240 V / 415 V AC (single‑phase supply) — compatible with standard domestic and commercial supply systems.
-
Tripping Mechanism: Thermo‑magnetic (overload + short‑circuit protection)
-
Tripping Curve / Characteristic: Typically “C‑curve” (or B/C depending on stock) for general‑purpose circuits — giving a balance between sensitivity and ability to handle inrush currents.
-
Mounting / Form Factor: DIN‑rail (standard 35 mm) — easy installation in standard distribution boards / breaker panels.
-
Protection Provided: Overload protection & short‑circuit protection — safeguards wiring and connected appliances/devices from faults.
-
Applications: Residential wiring (heavy socket circuits, larger appliances), light‑commercial installations, general power circuits requiring 40 A protection.
