ETI Prostik Unveils High-Quality Photovoltaic DC Combiner Boxes with Advanced Surge Protection

ETI Prostik,'s DC combiner boxes are designed to streamline the integration of solar panels into a single output, significantly simplifying the installation process of PV systems. What sets these combiner boxes apart is the integrated surge protection feature, which safeguards the solar panels and other electrical components from potential damage caused by voltage spikes and surges

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.

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).

SSQ Modular changeover switch

Modular changeover switches SSQ I-0-II (network - generator) enable simple and trouble-free switching of power supply sources in case of emergency (e.g. mains voltage failure). They are designed for installation in switchgear equipped with TH35 rails adapted for mounting modular devices. Switches can be sealed for the selected positions: I or II.

Advantages:

• the family of SSQ changeover switches expands the EVE modular system range,
• all changeover switches are made in modular form - module width 18 mm,
• the distance between the changeover switch contacts in the open state is larger than 3 mm per one pair of contacts, (two pair of contacts in the current path of changeover switch)
• the changeover switches are equipped with terminals enabling connection of conductors of cross-section : 16 mm2 for a “wire” type wire; 10 mm2 for a “ stranded wire” type cable.
