Most Common Tripping Characteristics in Miniature Circuit Breakers Explained

Understanding the tripping characteristics of MCBs is crucial for selecting the appropriate MCB type based on the anticipated load and protection requirements of electrical circuits, ensuring efficient and reliable electrical protection. The tripping characteristic, also known as the I-t curve, determines how quickly an MCB cuts off current during overloads or short circuits. The three most commonly used tripping characteristics are B, C, and D. We explain the differences between them and their use cases.

Smart City in Graz: A Model for Sustainable Urban Living

The concept of a "smart city" in Graz represents a forward-thinking approach to urban development, focusing on energy efficiency, resource conservation, and low emissions, all while ensuring the highest quality of life for its residents. This initiative is more than just a blueprint; it's a living, breathing example of how modern cities can adapt to the challenges of the 21st century.

Charger fuse for protection of highpower DC EV chargers

Safety is our top priority when it comes to DC (Mode 4) charging systems. That's why our Charger fuse plays a vital role in safeguarding DC circuits, capable of handling voltages up to 1000V DC and rated currents up to 600A. These specially designed fuses feature unique dimensions and connection contacts tailored to meet the specific requirements of each charging application.

The electrical protection of DC EV charging stations is of utmost importance in ensuring a safe and secure charging environment. Charger fuse boasts impressive characteristics, including a 1000V DC voltage rating, rated currents ranging from 50A to 600A, a breaking capacity of 30 kA, and compliance with standards IEC 60269-4 and IEC 60269-6. With a tested time constant of 3 mS, it proves suitable for a wide range of DC applications. Available in aR and gPV characteristic, which further enhances its performance and reliability, the Charger fuse is ideal for public fast (high power) charging stations, where the need for efficient and robust electrical protection is paramount.

Photovoltaic String Protection: Keeping the Current Flowing Safely

Photovoltaic 1500V d.c. systems

With the PV String protection, we have in mind the protection of PV modules against reverse currents. It is used in combination with central inverters where PV strings are usually combined in d.c. combiner boxes. Inside d.c. combiner boxes, PV strings are protected with cylindrical fuse‑links inserted in cylindrical fuse holders.

Frequency and voltage monitoring relay HRN-100

Multifunction voltage and frequency monitoring relay with LCD display for protection of devices connected to 3 phase network.

 Advantages:

• 3-wire or 4-wire connection (with or without neutral)
• Monitoring of upper and lower voltage & frequency in 3-phase circuits, phase sequence, failure and asymmetry incl. neutral fail (only in 4-wire connection).
• The device is supplied from monitored voltage.
• Both output contacts can be set individually.
• Measures real effective value of AC voltage (True RMS).
• Optional response delay of the output contact to the measured fault state or transition from the fault state to the OK state incl. delayed response of output contacts after connecting the power supply
• Optional closing or opening of the output contact when measuring a fault state (Fail Safe / Non Fail Safe).
