7PG1753-3BD10-4BE0 SIEMENS

The 7PG1753-3BD10-4BE0 is a sophisticated trip circuit supervision relay from Siemens' XR350 series, designed to continuously monitor the health and availability of trip circuits in electrical power systems. This three-element relay features self-resetting contacts and a self-resetting flag, ensuring reliable operation and clear indication of circuit status. The contact arrangement includes one normally open (1NO) and three normally closed (3NC) contacts, providing versatile signaling options for various control and alarm functions. Rated for 125V DC, this relay is suitable for use in a wide range of DC-powered protection schemes. Housed in a compact E3 case size (4U high), it offers space-saving installation in control panels and switchgear. The relay also incorporates four contacts for enhanced functionality. The alarm voltage rating is also 125V DC, ensuring consistent performance across different operating conditions. This particular model does not include a back EMF suppression diode, requiring external protection in certain applications. It is critical for maintaining the integrity of critical protection circuits.
