P1RC4P25AC300 – RES.CURRENT DEV.4P 25A IDN 300MA TYPE AC
Designed for dependable earth fault protection, the Lovato residual current operated circuit breaker P1RC4P25AC300 provides four-pole, type AC protection with a 25 A rating and 300 mA I∆n.
Why Choose the P1RC4P25AC300?
Designed for dependable earth fault protection, the Lovato residual current operated circuit breaker P1RC4P25AC300 provides four‑pole, type AC protection with a 25 A rating and 300 mA I∆n. This 4‑module RCCB installs on DIN rail to protect three‑phase and neutral circuits, supporting safe disconnection of residual currents in accordance with recognised IEC requirements for distribution and control panels.
Engineered to perform in demanding conditions, it offers Ui 400 V and Uimp 4 kV, with frontal IP20 protection and pollution degree 2. A wide operating temperature of -35 to +70 °C and max altitude 2000 m ensure versatility, while terminals tighten to 1.8–2 Nm for secure connections. Compact 4‑module design and 326 g weight simplify panel layout and service.
