ABB 2CSF202199R1250 Interruptor diferencial (RCCB), 2P, 25 A, 30 mA, Tipo A

Protect people and equipment from dangerous earth leakage currents with the ABB 2CSF202199R1250 residual current circuit breaker. This 2-pole RCCB detects AC and pulsating DC residual currents as low as 30 mA and instantly disconnects the circuit, preventing electric shock and reducing fire risk.

Who is it for

Electricians and panel builders who need a reliable, DIN-rail mounted residual current device for residential, commercial, or light industrial installations. It is suitable for circuits with a rated current up to 25 A and a voltage of 230 V AC.

Main features

• Type A residual current protection: trips on AC and pulsating DC fault currents.
• Sensitivity of 30 mA for personal protection against electric shock.
• Rated current of 25 A and rated voltage of 230 V AC.
• 2-pole design for single-phase systems.
• High short-circuit withstand rating of 10 kA.
• DIN rail mounting for quick installation in distribution boards.
• Wide operating temperature range from -25°C to +55°C.
• Screw terminals accept conductors up to 35 mm² rigid or 25 mm² flexible.
