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

The Spamel SPMO30B+C/1P is a high-performance single-pole surge protection device engineered to provide comprehensive Type 1 and Type 2 (Class B+C) protection for low-voltage electrical installations. By effectively diverting transient overvoltages resulting from atmospheric discharges or sudden switching operations, this device serves as a critical barrier against electrical surges that could otherwise damage sensitive equipment. Its robust design ensures consistent performance in both residential and industrial power systems, contributing to the overall stability and safety of the electrical infrastructure.

Advantages

This surge protection device offers a dual-stage defense mechanism by combining the high energy discharge capacity of Type 1 protection with the precise voltage limitation of Type 2 protection. The single-pole configuration allows for flexible installation in various distribution board setups, ensuring that critical circuits remain shielded from harmful voltage spikes. Its durable construction is built to withstand repeated surge events, providing long-term reliability and reducing the risk of costly equipment downtime or permanent damage to connected appliances and machinery.

Suitable for

• Residential electrical distribution boards
• Industrial power supply systems
• Protection of low-voltage installations against lightning-induced surges
• Safeguarding equipment from switching-related transient overvoltages

When it may not be suitable

This device is designed specifically for single-pole applications and may not be sufficient for complex multi-phase systems without additional compatible modules. It is not intended for use in high-voltage transmission lines or environments where surge requirements exceed the specified discharge capacity of the unit.

Key specifications

• Protection class: Type 1+2 (Class B+C)
• Configuration: Single-pole
• Application: Low-voltage power systems
• Function: Transient overvoltage protection

How to use

The device should be installed by a qualified electrician within the main distribution board or at the point of entry for the electrical installation. It must be connected in parallel with the power supply lines, ensuring that the grounding connection is secure and follows local electrical safety regulations. Proper wiring ensures that the device can effectively divert excess energy to the ground, protecting the downstream electrical components.

What to consider before purchase

• Verify the voltage rating of your electrical system
• Ensure there is sufficient space in the distribution board for a single-pole module
• Confirm that the grounding system is properly installed and functional

Usage recommendations

Regularly inspect the status indicator of the surge protection device to ensure it remains operational. If the indicator shows that the protection module has reached the end of its service life, it must be replaced immediately to maintain system safety.
