Spamel SPMO30B+C/4P Type 1+2 Surge Protection Device, 4-Pole

The Spamel SPMO30B+C/4P is a robust 4-pole surge protection device engineered to provide comprehensive safety for electrical installations. By integrating both Type 1 and Type 2 protection classes, this device acts as a primary and secondary defense mechanism against dangerous voltage spikes. It is specifically designed to mitigate the risks associated with atmospheric discharges, such as lightning strikes, as well as switching overvoltages that occur within power grids. Utilizing advanced varistor technology, the unit ensures a rapid response time and high energy absorption capacity, making it an essential component for maintaining the integrity of residential and industrial electrical systems.

Advantages

This surge arrester offers a dual-stage protection approach that significantly reduces the risk of equipment failure caused by transient overvoltages. Its 4-pole configuration allows for seamless integration into three-phase power systems, providing balanced protection across all phases and the neutral line. The device is built for durability and consistent performance, ensuring that sensitive electronic components remain shielded from electrical surges that could otherwise lead to costly repairs or system downtime. Its compact design facilitates easy installation in standard distribution boards, while the high-quality varistor components guarantee long-term operational reliability.

Suitable for

• Residential electrical distribution boards
• Industrial power supply systems
• Protection of sensitive electronic equipment
• Three-phase electrical installations

This device may not be suitable for applications requiring protection against sustained overvoltages or direct lightning strikes on the main power line without additional external lightning protection systems. It is also not intended for use in circuits exceeding its rated voltage capacity or in environments with extreme humidity or corrosive atmospheres that could compromise the internal components.

Key specifications

• Protection class: Type 1+2 (Class B+C)
• Number of poles: 4
• Technology: Varistor-based
• Application: Three-phase power grids

Installation should be performed by a qualified electrician in accordance with local electrical safety regulations. The device is typically mounted on a standard DIN rail within the main distribution panel. Ensure that the connection cables are kept as short as possible to minimize the impedance of the protective path, which enhances the effectiveness of the surge suppression. Proper grounding is essential for the device to function correctly and divert excess energy away from the protected equipment.

What to consider before purchase

• Verify the voltage compatibility with your existing electrical grid
• Ensure there is sufficient space on the DIN rail in your distribution board
• Confirm that the installation environment meets the manufacturer's temperature and humidity requirements
• Check if your system requires additional backup fuses for the surge protection device

For optimal performance, it is recommended to inspect the status indicator of the surge protection device periodically. If the indicator shows that the protection module has reached its end of life, the unit or the replaceable cartridge must be replaced immediately to maintain continuous system safety.
