Description

All-in-one measurement solution integrated under the molded circuit breaker, the MAD range offers unique advantages in terms of installation simplicity, reduction of components, and maintenance risks: - Measurements: The unit allows complete analysis of electrical circuits in three-phase or four-phase: - ➞ Instantaneous measurements: Single and compound voltages, current per phase and neutral, active, reactive, apparent power, frequency, power factor - ➞ Energy measurements: Active and reactive (positive and negative), apparent, reactive 4 quadrants - ➞ Quality: Voltage and current imbalance, distortion rates and harmonic content up to the 31st order - Accuracy: Active energy measurement class 0.5 - Electrical: Auxiliary power supply 80 … 270 VAC - Integration: The unit connects directly to the output terminals of the 3 phases of the molded circuit breaker. It acts as an extension of the breaker. The housing dimensions ensure perfect compatibility with the main manufacturers' circuit breakers, rated 400A and 630A. - Communication: Modbus RTU via RS485 port - Inputs and outputs: The measurement unit is equipped with 2 digital inputs and 1 programmable relay output - Circuit control and alarms: The relay is programmable for minimum or maximum threshold of current, voltage, power, phase imbalance, etc., allowing: - ➞ Protection of electrical circuits - ➞ Alarm functions in case of fault or inappropriate signal - ➞ Automatic load shedding in case of overload - Status feedback of electrical circuits: The 2 digital inputs allow monitoring the status of auxiliary circuits or devices and alert in case of failure or circuit break - Data logging: Energy and power indexes are recorded at a programmable frequency (from 1 minute). Data can be viewed via software and exported in .csv format - Supervision: Remote monitoring of measurements via Modbus, with third-party software or the free provided software. For local monitoring, optional embedded displays for cabinet doors are available in two formats, connected to the units via a single RJ12 cable - Cost reduction: - ➞ Component savings: Compared to a traditional installation, an integrated MAD measurement unit eliminates the need for: - External current transformers - Circuit breakers or fuse holders for voltage taps - Connection cables - ➞ Time saving: Faster installation due to fewer components - Maintenance reduction: The "all-in-one" design avoids failure risks on auxiliary components, connection cables, and connection points - Compliance: CE, RoHS, REACh - Applicable standards: IEC61557-12, GB/T 22264.7, IEC61326-1, IEC61010-1 - Associated products: - MAD-D72: 72×72 mm display - MAD-D96: 96×96 mm display - RJ12 cables to connect the display to the measurement unit - Technical specifications: - Measurement: Three-phase/four-phase, voltages, currents, power, frequency, power factor, energy, harmonics up to 31st order - Accuracy: Class 0.5 for active energy - Auxiliary supply: 80–270 VAC - Inputs/outputs: 2 digital inputs, 1 programmable relay output - Communication: Modbus RTU (RS485) - Compliance: CE, RoHS, REACh - Standards: IEC61557-12, GB/T 22264.7, IEC61326-1, IEC61010-1 - Compatible breaker ratings: 400A, 630A
