P1RC4P25A030 – RES.CURRENT DEV.4P 25A IDN 30MA TYPE A
Lovato’s residual current operated circuit breaker P1RC4P25A030 delivers reliable earth leakage protection in compact form.
Why Choose the P1RC4P25A030?
Lovato’s residual current operated circuit breaker P1RC4P25A030 delivers reliable earth leakage protection in compact form. This 4-module, 4-pole, Type A device is rated 25 A with 30 mA sensitivity for fast disconnection. It conforms to IEC/EN/BS 61008-1 and provides robust electrical ratings, including 400 V rated insulation (Ui) and 4 kV impulse withstand (Uimp), making it a dependable choice for modern distribution boards and control panels.
Engineered for tough environments, this RCD operates from -35 to +70 °C and up to 2000 m altitude, with IP20 frontal protection and pollution degree 2. Low power dissipation (0.5 W per pole) and a secure terminal torque of 1.8 to 2 Nm aid efficient, safe installation. At just 326 g and four DIN modules wide, it simplifies panel layouts without compromising protection.
