Base for MC 50-B U VDE limiter 5096839

Electrical installation protection with MC 50-B U VDE surge limiter base

This surge limiter base is a key element of the protection system, ensuring the safety of electrical installations from the effects of current surges and overvoltages. Designed to work with MC 50-B VDE and MCD 50-B limiters, it provides reliable protection for devices and cables. Mounting is done on a standard DIN TH-35 mm mounting rail, which facilitates integration with existing systems.

Application and design features

This base is characterized by high efficiency in discharging surge energy, thanks to its ability to withstand peak currents of up to 50 kA (8/20 µs) and surge currents of 125 kA (10/350 µs). Made of high-quality materials, it ensures durability and reliable operation. Its compact size – only 2 modules – allows for efficient use of space in the switchgear cabinet. The maximum wire cross-section that can be connected is 50 mm², which allows its use in installations with high loads. A protection level of 2 kV further increases the safety of the entire system.

Why choose this surge limiter base?

• Versatility: Compatible with various types of limiters from the MC and MCD series.
• High resistance: Protects against overvoltages with high surge energy values.
• Easy installation: Standard mounting on a DIN TH-35 mm rail speeds up installation.
• Durability: Made of solid materials guaranteeing long-term operation.
• Safety: Provides effective protection against damage caused by overvoltages, protecting devices and electrical infrastructure.
• Ready for signaling: Although there is no built-in operation signaling on the device, the possibility of using additional signaling elements increases control over the protection status.
• Compliance with standards: The product meets the requirements of the VDE standard, which confirms its high quality and safety of use.

Additionally, the set includes plug-in covers that facilitate connection identification and ensure an aesthetic appearance of the installation. The degree of protection IP20 means that the device is protected against touching with a finger and against the ingress of solid bodies larger than 12.5 mm – a standard protection for devices mounted inside electrical switchgear cabinets.
