ABB S262-D20 Circuit Breaker

ABB S262-D20 is a two‑pole miniature circuit breaker (MCB) from ABB’s S262‑D product family, rated for 20 A in 230/400 V AC distribution systems. Designed for DIN‑rail mounting in panel boards, this 2‑pole device provides overcurrent protection for branch circuits and helps prevent faults from escalating into damage or fire. The D‑type characteristic delivers a trip curve suitable for circuits with moderate inrush loads, making it a versatile choice for protection of motor starters, power supplies, lighting controls, and other common distributed loads in commercial and light industrial panels. Built around a reliable thermal‑magnetic trip mechanism and a compact form factor, the S262‑D20 is intended to integrate smoothly with other DIN‑rail devices in standard low‑voltage distribution architectures, delivering targeted protection for feeders, outlets, and control circuits.
