Product information for EPA 50275390:
The EPA PECON+ (manufacturer's part number 50275390) is a protective earth conductor monitoring device for single-phase and three-phase TN systems with neutral conductor. It provides continuous monitoring of the leakage current in the protective earth conductor (PE) and disconnects via an integrated alarm relay if the threshold is exceeded. The device is specifically designed for installations with frequency converters and other electronic equipment, where the protective earth conductor plays a critical role in electrical safety.
Applications
The device is installed directly at the power supply point of a machine or system to ensure the integrity of the protective earth conductor. It is designed for 1- and 3-phase TN networks (TN-S systems), where the protective earth conductor runs alongside the neutral conductor (N) and phase conductors (L). Monitoring is based on leakage current, which increases in the event of a break or degradation of the protective earth conductor. The device is particularly suitable for industrial environments with electronic controls, drives, or frequency converters, where a break in the PE conductor could lead to hazards.
Functions and Features in Detail
The PECON+ monitors the leakage current in the protective earth conductor and responds if the threshold of more than 3.5 mA AC is exceeded. The tripping threshold is below 1000 Ω, ensuring high sensitivity to faults in the protective earth conductor. Upon detecting a fault, the integrated alarm relay switches off within less than 0.4 seconds. The status is indicated by an LED showing three states: OK, Phase Fault, and Alarm. A test button allows manual verification of the device’s functionality. The device is suitable for use in installations with frequency converters and other electronic equipment, where the protective earth conductor plays a critical role.
Technology Explained Simply
The device operates with a supply voltage of 200 to 230 VAC (±10 %) at a frequency of 50/60 Hz (±5 %). The power consumption is 5 VA, which represents a low load on the network. The protection rating is IP20 at the terminals and IP20 on the enclosure, protecting against finger contact and solid objects, as well as splashing water, but not against dust or water ingress. The operating ambient temperature ranges from −15 °C to +40 °C, while storage is possible up to +70 °C. Mounting is done on a TS35 DIN rail in accordance with DIN EN 50022, enabling standardized installation in enclosures.
Compatibility and Accessories
The device is designed for 1- and 3-phase TN networks (L/N/PE, L1/L2/L3/PE, L1/L2/L3/N/PE). The alarm contact is potential-free and can switch loads up to 250 VAC/5 A or 30 VDC/2 A. The terminal cross-sections are limited to a maximum of 4.0 mm² solid and 2.5 mm² flexible with a sleeve. No special accessories are required, as the device is designed as a standalone monitoring unit. Certifications include CE, and standards comply with DIN EN 50178/VDE 0160 and DIN EN 61800-5-1.
Installation and Mounting
Mounting is done on a DIN rail TS35 (DIN EN 50022). The device has a width of 45 mm and dimensions of 75 × 45 × 125 mm. The terminals are designed for the specified cross-sections, with flexible conductors requiring a sleeve. Installation is performed directly at the machine’s power supply point, ensuring correct connection of phases, neutral conductor, and protective earth conductor. The test button allows for quick functional testing after installation.
Operational Advantages
The PECON+ provides reliable, continuous monitoring of the protective earth conductor, enabling early detection of potential hazards caused by breaks. The short response time of less than 0.4 seconds ensures rapid reaction. The LED indicator allows visual monitoring of the operating status. Compatibility with frequency converters and electronic equipment makes it an ideal solution for modern industrial installations. DIN rail mounting and low power consumption facilitate integration into existing control panels.
Scope of Delivery
The delivery includes the protective earth conductor monitoring device PECON+ for TN networks. No additional components such as batteries, cables, or mounting materials are included.
