Description
Description
The Onesto 32 A 3P 3 kA Mini Circuit Breaker is a robust and versatile protection device designed for three‑phase or multi‑phase electrical systems. Its triple‑pole configuration ensures that all three live conductors are disconnected simultaneously — offering full circuit isolation and enhanced safety, especially for three‑phase loads or multi‑wire installations.
With a rated current of 32 A per phase and a short‑circuit breaking capacity of 3 kA, this MCB delivers dependable protection against overloads and short‑circuit events — helping prevent damage to wiring, motors, and connected equipment. The thermo‑magnetic (C‑curve) tripping mechanism ensures prompt response under fault conditions while tolerating normal startup inrush currents typical of motors or inductive loads.
-
Type: Miniature Circuit Breaker (MCB), Triple‑Pole (3P)
-
Rated Current (In): 32 Amps — suitable for medium‑load 3‑phase circuits or three‑wire systems needing 32 A per phase.
-
Poles / Configuration: 3‑pole — disconnects all three live conductors, providing full isolation for three‑phase or multi‑phase installations.
-
Breaking Capacity (Icu / Ics): 3 kA — capable of safely interrupting overloads or short‑circuit fault currents up to 3000 A.
-
Rated Operational Voltage (Ue): 415 V AC for 3P (standard three‑phase supply) per Onesto’s documentation of multi‑pole breakers.
-
Tripping Mechanism / Curve: Thermo‑magnetic with typical “C‑curve” characteristic (or as per batch) — provides balanced protection, tolerant of normal inrush current but trips reliably on faults.
-
Mounting / Form Factor: DIN‑rail mount (standard 35 mm rail) — easy installation in distribution boards / breaker panels.
-
Standards & Ratings: Complies with relevant MCB standards (e.g. IEC/IEC60898‑1) and suitable for circuits requiring 240/415 V, 50/60 Hz.
-
Protection Offered: Overload protection & short‑circuit protection — safeguards wiring, appliances, motors or equipment connected to three‑phase circuits.
-
Typical Applications: Industrial, commercial or residential three‑phase installations; small to medium machinery; three‑phase motors; multi‑phase power circuits and sub‑panels requiring 32 A per phase protection.
