Overcurrent Release Acti9 MX – Protection and Reliability of Installations

The Acti9 MX-230/400 overcurrent release is an element designed to protect electrical installations, intended for use with miniature circuit breakers (MCB). Its task is to respond to sudden current surges, protecting the circuit from overloads and damage. Mounted on a DIN rail, it is an integral part of the protection system, ensuring its proper functioning.

Functionality and Application

This release is an auxiliary element that expands the capabilities of a standard circuit breaker. Thanks to it, the installation is better prepared for shock loads, such as starting electric motors or powering devices with high power consumption. The control circuit voltage can range from 100V to 415V AC (50/60Hz) or from 110V to 130V DC, ensuring wide compatibility with various power systems. The device is only 18 mm wide – one module – which allows for optimal use of space in the distribution board.

Advantages and Benefits

• Protection against overloads: The release effectively protects the circuit from the effects of sudden current surges, minimizing the risk of damage to equipment and wires.
• Versatility: The ability to be powered by both AC and DC voltage makes the device universal and can be used in various applications.
• Compact dimensions: A width of one module makes installation easier and allows for efficient use of space in the switchboard.
• Compatibility: Designed to work with Acti9 circuit breakers, creating a coherent and reliable protection system.
• Up to 4 main contacts: The ability to connect up to four main contacts with a maximum current of 125A increases the flexibility of application.
• Solid construction: Ensures long-lasting and trouble-free operation in various environmental conditions.

Technical Parameters in Practice

The MX-230/400 release is characterized by high precision and reliability. The rated voltage of 415V and the ability to operate in both AC and DC systems make it an ideal solution for a wide range of industrial and commercial applications. The lack of signaling contacts does not affect its functionality – the device operates discreetly, providing protection without unnecessary interference. The use of an overcurrent release allows for the safe starting of devices requiring high starting current, such as motors or transformers.
