Dehn 953201 Type 3 Surge Arrester 2P 2kA 0.63kV

The Dehn 953201 is a high-quality Type 3 surge arrester engineered to provide essential protection for sensitive electronic devices within low-voltage electrical systems. This 2-pole device is designed to mitigate the risks associated with transient overvoltages, acting as a final stage of protection in a coordinated surge protection concept. By maintaining a low voltage protection level, it ensures that connected equipment remains safe from electrical spikes that could otherwise lead to premature failure or data loss.

Advantages

This surge arrester offers a compact design that allows for easy integration into existing distribution boards or terminal boxes. Its robust construction ensures reliable performance under standard operating conditions, providing a consistent barrier against voltage fluctuations. The device is specifically optimized for terminal protection, making it an effective solution for safeguarding delicate electronics in both residential and commercial environments.

Suitable for

• Protecting sensitive electronic equipment in residential buildings
• Safeguarding office hardware and communication devices
• Final stage protection in low-voltage electrical installations
• Integration into terminal equipment enclosures

When it may not be suitable

This device is not intended to serve as the primary surge protection for an entire building. It should not be used as a substitute for Type 1 or Type 2 surge arresters, which are required for protection against direct or indirect lightning strikes at the main service entrance.

Key specifications

• Type: Type 3 surge arrester
• Number of poles: 2
• Nominal discharge current: 2 kA
• Voltage protection level: 0.63 kV
• Application: Low-voltage systems

How to use

The Dehn 953201 should be installed by a qualified electrician in accordance with local electrical safety regulations. It is typically mounted on a standard DIN rail as close as possible to the equipment being protected. Ensure that the wiring connections are secure and that the device is integrated into the circuit following the manufacturer's wiring diagram to maintain optimal protection levels.

What to consider before purchase

• Verify that the voltage protection level is compatible with your sensitive equipment
• Ensure the device is used as part of a coordinated surge protection system
• Confirm available space in your distribution board or terminal enclosure
• Check that the installation environment meets the technical requirements for Type 3 devices

Usage recommendations

For maximum effectiveness, ensure that the cable length between the surge arrester and the protected device is kept as short as possible to minimize inductive voltage drops during a surge event.
