DESCRIPTION

The 4SH4401Y is an AC-operated industrial relay from Fuji Electric's SH Series, featuring 4 normally open (NO) auxiliary contacts configured as a 4-pole relay. This relay incorporates bifurcated contacts that provide high contact reliability with a minimum operational voltage and current of 5V and 3mA DC, enabling direct input to electronic control circuits. The relay conforms to international standards including IEC, NEMA, BS, and VDE, with UL, CSA, BV, and Lloyd approvals. It features a continuous current rating of 10A at 120V AC (60A make, 6A break), with additional ratings at 240V and 480V AC. The relay is compatible with conventional mounting on IEC or DIN Standard 35mm rails and supports optional auxiliary contact blocks and function units for field flexibility. Common applications include industrial automation, electronic device control, and expandable control systems where high contact reliability and international compliance are essential.
