Surge arrester 24V type MDP-4 D-24-T 5098431

Surge protection barrier for signaling systems – protection and reliability

This is a compact surge protection barrier designed to protect sensitive devices in signaling and control systems. Designed for mounting on a TH-35 mm DIN rail, it is a key element in protecting against the effects of overvoltages and atmospheric discharges. Its versatility makes it suitable for many installations, both in commercial and industrial buildings.

Construction and application

The MDP-4 D-24-T barrier is a series device that directly grounds the shield, minimizing the risk of damage caused by induced overvoltages. It is designed to operate with DC voltage up to 28V and AC voltage up to 20V. This makes it perfect for protecting data lines, automation systems and other devices sensitive to interference. It is worth noting that the design allows testing of the protective circuit using the Life Control function, which allows for regular verification of the device's efficiency.

Advantages and benefits

• Compact dimensions: A width of only 8.7 mm saves space in the switchgear cabinet.
• Direct shield grounding: Provides effective protection against electromagnetic interference.
• Screwless connection terminals: Facilitate and speed up mounting and connection of wires.
• Wide frequency range: Operates in the range from 0 to 100 MHz, which guarantees protection for a wide spectrum of signals.
• Life Control testing function: Allows regular control of the protective circuit's efficiency.
• UL (4DG1) compliance: Confirms the high quality and safety of the device.
• Rated current 0.58 A: Suitable for most standard applications in signaling systems.
• Wire/ground protection level 800 V: Provides a high degree of protection against differential overvoltages.

The MDP-4 D-24-T barrier is not only a protective element – it is an investment in the reliability and long-term functioning of electrical and electronic installations. Its solid construction and advanced functions make it an ideal choice for both professional installers and end-users looking for effective protection of their devices.
