Description
The Onesto 40 A 2P 3 kA Mini Circuit Breaker is a robust and dependable over‑current protection device — ideal for residential, commercial, or light‑industrial installations where enhanced circuit safety is needed. With its double‑pole design, the breaker disconnects both live and neutral conductors (or both phases where applicable), ensuring full isolation and higher safety compared to single‑pole breakers.
Designed for circuits with higher load demands, this breaker delivers 40 A rated current and a short‑circuit breaking capacity of 3 kA, effectively safeguarding wiring and connected equipment against overloads or short‑circuit faults. The thermo‑magnetic (C‑curve) tripping mechanism responds quickly and reliably to fault conditions, while DIN‑rail mounting ensures straightforward installation in standard distribution boards or breaker panels.
-
