Description
The Onesto 20A 3P 3kA Mini Circuit Breaker is a reliable and compact solution designed to provide robust three‑phase circuit protection. With a 3‑pole configuration, it disconnects all live conductors simultaneously — ensuring full circuit isolation for safety and compliance in multi‑phase wiring systems.
Rated for 20 A per pole and a short‑circuit breaking capacity of 3 kA, this breaker effectively protects wiring, motors, and connected equipment from overloads or short‑circuit events. The thermo‑magnetic (C‑curve) tripping mechanism delivers a dependable response to fault conditions while tolerating normal inrush currents — ideal for motors or inductive loads.
-
Type: Miniature Circuit Breaker (MCB), 3‑Pole (3P)
-
Rated Current (In): 20 Amps
-
Number of Poles / Configuration: 3‑pole — disconnects all three live conductors (for three‑phase circuits) or three‑wire systems.
-
Breaking Capacity (Icu / Ics): 3 kA — safely interrupts short‑circuit or overload fault currents up to 3000 A.
-
Rated Operational Voltage (Ue): 240/415 V AC (for 3‑phase supply / multi‑wire systems)
-
Tripping Mechanism / Curve: Thermo‑magnetic, typically “C‑curve” — good for general-purpose circuits and allows some inrush-current tolerance (e.g. motors, inductive loads).
-
Mounting / Form Factor: DIN‑rail mount (standard 35 mm rail) — straightforward installation in distribution boards or 3‑phase panels.
-
Protection Provided: Overload protection & short‑circuit protection — safeguards wiring and equipment against overcurrent and faults.
-
Typical Applications: Three‑phase or multi‑wire circuits in residential, commercial or light‑industrial environments; small 3‑phase motors, light machinery, three‑phase sub‑circuits, or any load requiring 20 A per phase.
