Understanding Your Company’s Carbon Footprint

What is a carbon footprint?

A carbon footprint is the total amount of carbon dioxide (CO₂) and other greenhouse gases (GHGs) emitted by an activity, product, event, person, or organization. It is measured in tonnes of CO₂ equivalent (tCO₂e).

KZS-1MS: Compact, Voltage-Independent Protection in One Module

The KZS-1MS is one of the first electromechanical (voltage-independent) residual current circuit breakers with overcurrent protection (RCBO) on the EN/IEC market available in only one modular width.

RCBOs combine residual current detection, short-circuit, and overload protection in a single device, providing both electric-shock protection and line protection. This all-in-one solution enhances reliability, improves system availability, and simplifies installation planning.

KZS-1M-UNI: Compact Protection for Modern Electrical Installations

KZS-1M-UNI is a versatile solution for modern electrical installations. With the option to connect the electrical supply from either the top or the bottom, it provides greater flexibility and simplifies installation in various setups.

In the 1990s, a new type of protective device began appearing in electrical distribution boards in Slovenia – the so-called combined protective device (KZS), a commercial name introduced to the market by ETI Izlake.

There are two main types of residual current protective devices (RCDs):

• RCCB (Residual Current Circuit Breaker), which provides protection against residual current, and

• RCBO (Residual Current Circuit Breaker with Overcurrent protection), which in Slovenia is referred to as KZS (as our house name has been widely adopted).

In this article, we will focus on the RCBO version, i.e. the one that also includes overcurrent protection. Over the last 30 years, KZS devices have evolved significantly: from two-pole and four-pole versions with electromechanical tripping mechanisms to today’s compact electronic models.

National GZS Innovation Awards Presented at Innovation Day 2025

As part of Innovation Day 2025, held at Brdo pri Kranju, the Chamber of Commerce and Industry of Slovenia presented national awards to the most successful innovators in Slovenia. The event brought together companies, research institutions and individuals whose solutions significantly contribute to technological progress and the competitiveness of the Slovenian economy.

A total of 245 innovations were submitted this year, involving more than 1,300 innovators. Ten gold, 27 silver and 15 bronze awards were presented, along with one special award for a breakthrough invention. Innovators from the Zasavje region were also among the national award recipients, once again confirming the region’s strong innovation potential.

Product Carbon Footprint (CFP): Measuring the Environmental Impact of Products

The Product Carbon Footprint (CFP) represents the total greenhouse gas emissions associated with a product throughout its life cycle—from raw material extraction to production, use, and end-of-life. This comprehensive measure is expressed in CO₂ equivalents (CO₂e), providing a clear picture of a product’s environmental impact.

When Should You Use an F-Type RCCB Instead of an A-Type?

In recent years, the question “When should I use a Type F residual current circuit breaker (RCCB) instead of a Type A?” has become increasingly relevant. As electrical installations become more complex, incorporating frequency-controlled drives, modern appliances, and sensitive electronics, the line between appropriate and insufficient protection can be blurred.

This post aims to demystify the decision-making process between Type A and Type F RCCBs by exploring their capabilities, limitations, and ideal application environments. Whether you're designing a residential, commercial, or light-industrial installation, understanding when to step up from Type A to Type F could mean the difference between safe, stable operation and frustrating, or even hazardous, outcomes.

Aluminium: The Lightweight Metal Driving a Heavyweight Transition

Aluminium is all around us – in cans, cars, cables and construction. But behind its low weight lies a high-impact industry. As global efforts accelerate towards net-zero targets, aluminium’s unique properties are making it increasingly essential – and raising critical questions about how sustainably we can meet future demand.

Life Cycle Assessment (LCA): A Key to Sustainable Product Development

Life Cycle Assessment, or LCA, is a scientific methodology used to evaluate the environmental impact of a product, process, or service throughout its entire life cycle. By conducting an LCA, businesses gain vital insights into how their operations affect the environment—from greenhouse gas emissions and ozone layer depletion to energy and material consumption.

Silver’s Dual Role: Essential for Green Tech, Prized for Value

Silver is no longer just a shiny precious metal—it’s a vital component in the global energy transition. Its unique combination of high electrical conductivity, reflectivity, and antibacterial properties makes it indispensable in solar panels, semiconductors, and medical devices. But as demand from clean energy and high-tech sectors surges, supply is struggling to keep pace.

RCCB Overheating: Causes, Consequences, and Prevention Strategies

Residual Current Circuit Breakers (RCCBs) are essential safety devices designed to protect against electrical shock and fire hazards by detecting earth leakage currents. However, these critical safety components are themselves vulnerable to overheating, which can lead to catastrophic failure, fires, and loss of electrical protection. This whitepaper provides a comprehensive analysis of RCCB overheating phenomena, examining the fundamental causes, serious consequences, and effective prevention strategies based on current industry standards and research findings.

Zinc: The Industrial Shield with Growing Green Relevance

Zinc has been known for millennia, primarily as a component in brass, but isolating it in pure form took time. It wasn't until the 12th or 13th century in India that zinc was produced in significant quantities. In Europe, large-scale production only began centuries later. The industrial revolution propelled zinc into mainstream use, particularly in galvanization — coating iron and steel to prevent rust and extend product life.
