1SDA116225R1

ABB 1SDA116225R1 Formula DSP P1B 160 TMD 125-1250 4P F F is a 4-pole fixed Moulded Case Circuit Breaker (MCCB) designed for reliable protection and switching in low-voltage electrical distribution systems.

This MCCB is equipped with a thermomagnetic (TMD) release for protection against overload and short-circuit conditions. It features front terminals and a fully rated neutral (InN=100%), making it suitable for electrical distribution panels where reliable protection of all four poles, including the neutral, is required.

The P1B 160 frame has a 160 A rated uninterrupted current, while this specific version has a 125 A rated current and a 87.5–125 A setting range. It is rated for 500 V AC, with 750 V insulation voltage and 8 kV impulse withstand voltage. ABB specifies 25 kA service short-circuit breaking capacity at 240 V AC for this model.
