The 1492-RCDA4B40S is a four-pole residual current device (RCD) designed to detect earth leakages in electrical circuits. It features a sensitivity of 100 mA and a maximum voltage rating of up to 480Y/277 VAC (max US 400 VAC). The device has a built-in depth of 67 mm, operates at a frequency of 50/60 Hz, and has an IP2X ingress protection rating. With a breaking capacity of 1 kA (residual) and 10 kA (short-circuit) at its maximum voltage, the 1492-RCDA4B40S provides reliable ground fault protection with a Type A tripping characteristic and instantaneous break time. It is suitable for general-purpose applications where ground fault detection is essential.
