Kopp Circuit Breakers

Reliable circuit protection is fundamental to any electrical installation, and Kopp breakers and DIN modular devices represent a complete system designed for safety, durability, and ease of integration. Built according to IEC 60898 and EN 61009 standards, Kopp’s modular range includes circuit breakers, residual current devices (RCDs), surge protection units, and complementary DIN rail accessories — providing end-to-end protection for both residential and industrial power networks.

Complete Range of Kopp Modular Protection Components

The Kopp modular protection components portfolio ensures comprehensive system coverage — from basic overload protection to advanced fault monitoring and transient surge suppression. This makes them suitable for new builds, retrofits, and energy management upgrades.
The range includes:

• Kopp circuit breakers – thermal-magnetic protection for overloads and short circuits.
• Kopp residual current devices (RCDs) – life-saving protection against earth leakage currents.
• Kopp surge protection devices (SPD) – transient voltage suppression for sensitive electronics.
• Kopp DIN rail accessories – marking, wiring, and mounting aids for optimized installation.
• Kopp distribution panel devices – compact and modular for reliable control panel integration.

Each component is designed to fit seamlessly within Kopp enclosures and standard DIN rail systems (35 mm), ensuring compatibility across various panel architectures

Kopp Circuit Breakers

Kopp circuit breakers form the core of low-voltage protection systems. They combine thermal and magnetic tripping mechanisms to protect cables, devices, and circuits from both overloads and short circuits.
Available in single- to four-pole versions with current ratings from 1 A to 63 A, Kopp breakers cover a broad spectrum of applications — from lighting circuits to industrial motor protection.

Key features:

• Curve types B, C, and D for different load characteristics
• High mechanical endurance (up to 20,000 operations)
• Rated breaking capacity up to 10 kA
• Contact position indicator for quick diagnostics

Practical insight: Installers often favor Kopp MCBs for their stable torque screw terminals and consistent calibration across batches, which reduces error margins during bulk installation.

Kopp Residual Current Devices (RCDs)

Kopp residual current devices detect earth leakage faults and disconnect circuits within milliseconds to prevent electric shock or fire.
Available in Type AC, A, F, and B variants, they are tailored to both residential and industrial environments, including systems with variable frequency drives or EV charging infrastructure.

Technical benefits:

• Sensitivity options: 10 mA, 30 mA, 100 mA, 300 mA
• Dual terminal configuration for easier wiring
• Test button and visual fault indication
• Conformity with EN 61008/61009 standards

Expert note: In modern installations with multiple RCDs, selectivity coordination (time-delayed S-type) ensures that only the affected line disconnects, preserving continuity on other circuits — a key advantage in data centers and industrial sites

Kopp Surge Protection Devices

Transient overvoltages caused by lightning strikes or grid switching events can destroy sensitive equipment. Kopp surge protection devices (SPDs) are designed to limit these voltage spikes and divert the energy safely to earth.
Kopp offers both Type 1 and Type 2 surge arresters for coordinated protection at different installation levels.

Typical parameters:

• Nominal discharge current: 5–20 kA
• Maximum discharge current: 40–80 kA (depending on class)
• Replaceable modules for simplified maintenance
• Visual and remote indication contacts

Professional insight: Combining Kopp SPDs with proper equipotential bonding and grounding dramatically increases system lifespan — a common best practice in telecom towers, commercial buildings, and photovoltaic systems.

Kopp DIN Rail Accessories

A complete modular setup requires not only breakers but also reliable Kopp DIN rail accessories. These include:

• Terminal markers and numbering strips
• Phase busbars and combs for simplified wiring
• Blank covers and separators for unused slots
• DIN end stops and grounding terminals

These small yet critical components reduce wiring time, minimize connection errors, and ensure compliance with panel design standards like IEC 61439.

Kopp Distribution Panel Devices

The Kopp distribution panel devices category integrates circuit breakers, RCDs, SPDs, and control modules into a cohesive panel system. Compact form factors and standardized module widths make Kopp products ideal for dense installations, such as apartment switchboards or industrial automation cabinets.

Expert tip: When designing multi-row distribution boards, balancing heat dissipation and circuit layout is essential. Kopp’s modular housing is designed with optimized airflow slots and uniform terminal spacing, improving both safety and serviceability.

Technical Compatibility and Integration

All Kopp breakers and DIN modular devices are designed for 230/400 V AC systems and are compatible with copper or aluminum conductors. The use of silver-alloy contacts ensures stable switching performance even under high inrush currents.
Their uniform modular design allows easy integration with smart monitoring relays, energy meters, and remote-controlled modules for future-ready installations.

Compliance standards:

• IEC 60898 (MCB)
• IEC 61008/61009 (RCD)
• IEC 61643-11 (SPD)
• RoHS / REACH conformity
