Din rail modular devices

DIN is an acronym for Deutsches Institut fur Normung, which translates into English as ‘German Institute for Standardization’. Din rails are long metal strips that are used to mount and securely attach electrical and industrial control products. Explore our wide range din rail modular devices such as enclosures, miniature circuit breakers - MCB, residual current devices – RCD, surge protection devices – SPD, arc fault detection devices – AFDD, as well as smart solutions of auxiliaries, contactors, relays, meters and communication interfaces. From the primary to the most advanced protection needs, the din rail device 9 series of Schneider Electric offer the final level of compliance, performance, and reliability. These Acti 9 products comes with various specifications and different ranges.
What is a Miniature Circuit Breaker (MCB)?

A Miniature Circuit Breaker (MCB) is a safety device that protects electrical circuits from overloads and short circuits. Schneider Electric’s range, including Acti9 C120 and Acti9 xC60, offers high reliability for safer homes and industrial setups.

We offer:
  • High breaking capacity
  • Quick trip response
  • Easy DIN rail mounting
How a Miniature Circuit Breaker Operates

Do you wonder how an MCB works? An MCB (Miniature Circuit Breaker) works by automatically switching off the electrical circuit when it detects an overload or short circuit. It operates through a thermal or magnetic trip mechanism, protecting appliances from damage. When the current exceeds a safe level, the MCB disconnects power. This ensures safety and prevents electrical hazards.

What are the functions of a Miniature Circuit Breaker (MCB)?

Schneider Electric’s Miniature Circuit Breakers (MCBs) are designed to deliver reliable circuit protection across homes and industries. Their core functions include:

  • Interrupting current during overloads and short circuits
  • Preventing damage to connected devices
  • Enhancing safety with quick fault detection
  • Supporting long-term, maintenance-free use

Acti-9 RCD is an easy-to-install and efficient range of devices, suitable for both commercial and residential buildings to provide optimum protection against electrocution, fire, and earth fault. Our skilled team of professional experts has designed an enigmatic range of Residual Current Devices like Vigi for Acti 9 C120, Vigi for Acti 9 NG 125, IDPN Vigi, etc. that provides service continuity and efficiency in most electrical applications installed in homes and industries.

Residual Current Devices (RCDs) enhance electrical safety by detecting imbalanced current, or leakage, and instantly disconnecting power to prevent electric shock. This vital technology protects people from fatal electrical accidents. Types include fixed, portable, and socket-outlet RCDs, offering protection across various applications. Schneider Electric's RCDs, a part of its comprehensive electrical safety portfolio, are a preferred choice for protecting people and equipment in residential, commercial, and industrial environments.

What is a Surge Protector?

A surge protector is an electronic device used to protect the connected equipment from voltage inconsistencies. It helps in rerouting any unsafe current and ensures a consistent power flow to all connected components. Most electronic devices are shipped with voltage-sensitive components that can be easily damaged in situations of a sudden voltage spike. A surge protector detects any form of voltage inconsistency in the circuit and protects the connected devices from both over and under-voltage.

Why do we need Surge Protector?

To save the system from different magnitudes of surge voltages, the capacity or magnitude of the arrestor varies. The amplitude can range from a few millivolts to some ten thousand volts. Schneider Electric Singapore comes with a series of surge protection devices that can be installed in the system to ensure protection from over or under voltage. To use this, install a plug-in, point-of-use electrical surge protector. The device can be plugged into a grounded electrical outlet or can be directly connected into the appliance. Lightning protective devices are developed, tested, and classified according to their international series of product standards, and they have defined surge protection functions and performance parameters to make them suitable for use with similar protection concepts.

Hence, it is imperative to have a surge protection device to safeguard your house, family, colleagues and friends from any harm. Every year, many electronic devices get damaged due to transient voltages. This major mishap is protected by surge protection devices. Surge protectors are also used in electrical installation systems for protecting them.

Schneider Electric offers a wide variety of surge protectors that help in keeping your loved ones safe. Their Acti 9 range of surge protectors have been in demand since its inception and is preferred by almost every household and construction projects. You can know more about this product here.

Power Sockets are essential for reliable electrical systems and modern technology. Faulty or outdated outlets cause loose connections, wasted energy, shocks, equipment damage, and serious fire hazards, creating constant safety concerns for customers. They complete the circuit and supply stable power to appliances, so work and daily life remain uninterrupted. Upgrading them prevents dust buildup, supports flexible placement, and restores worn enclosures that expose risks over time.


Our Power Sockets improve protection, deliver long-lasting durability, and support modern wiring needs. With robust enclosures, flexible installation options, and advanced designs, our sockets support smart homes and commercial spaces, reducing downtime and enhancing convenience. Choosing us means trusted innovation, better compliance, and a safer environment built for future technology.
