The 1409-N1 by Allen Bradley is an arcing ground fault sensor engineered for precise fault detection. This unit is capable of withstanding an insulation voltage of 1500 volts. The sensor operates effectively at a rated voltage of 600 VAC, making it suitable for various industrial applications.

With a relay contact configuration of SPDT (Single Pole Double Throw), this device has a contact rating of 10 A when operating with 240 VAC circuits. It provides quick detection of fault currents, identifying minimum levels as low as 5 A and maximum thresholds of up to 200 A.

Designed for versatility, the 1409-N1 is mountable in NEMA 1 and NEMA 2 enclosures, ensuring compatibility with standard installations. The control circuit frequency is set at 50/60 Hz, with an operational voltage of 120 VAC. The sensor is fitted with a window diameter of 1-9/16 inches (40 mm) for optimal functionality. Furthermore, the response time from detection to action is remarkably short, measuring under 25 milliseconds, which enhances safety in any electrical setup.
