LED surge protector type ÜSM-10-230I2P+PE 5092426

Surge protection for electrical installations

This type 2+3 surge protector, catalog number 5092426, is a key element in protecting electrical installations and electronic devices from the effects of sudden voltage spikes. Designed in accordance with DIN EN 61643-11, it is perfect for 230/400 V networks, offering comprehensive protection. It is particularly recommended for protecting sensitive receivers, such as LED drivers, where stable power supply is critical for proper operation.

Functionality and application

This surge protector combines the features of type 2 and 3 arresters, which means it provides both initial protection against strong surges and accurate damping of residual transient voltages. Its compact size allows for easy installation in various places – in connection boxes, lighting fixtures, cable ducts or underfloor systems. Optical indication of the device status informs about its operation and any failure, and the power circuit disconnection function in case of damage further increases safety.

Key features and benefits

• Versatile application: Ideal for protecting 2-phase lamps (with power reduction) and devices equipped with a PE connector.
• High efficiency: Ensures voltage reduction below 1300 V (protection level), minimizing the risk of damage to connected devices.
• Status indication: Optical indication of operation facilitates diagnostics and quick response in case of failure.
• Safety: Power circuit disconnection function in case of arrester damage protects against further problems.
• Compact dimensions: Allow installation in hard-to-reach places, such as mast connection boxes or inside lighting fixtures.
• Discharge current resistance: The protective circuit withstands a discharge current of up to 10kA, providing effective protection even during strong surges.
• Compliance with standards: Meets the requirements of DIN EN 61643-11, guaranteeing high quality and reliability.

The surge protector is characterized by a protection level of 1.3 kV for both L-N and overall. The maximum wire cross-section that can be connected is 1.52 mm². The device indicates operation optically and has a protection degree of IP20 and the highest permanent operating AC voltage at 255 V. The mounting type is "Other", which means flexibility in choosing the installation method to suit specific conditions.
