Surge Protective Device (SPD) Factory

How Do I Choose a Surge Protective Device?

When it comes to selecting a surge protective device, there are several factors to consider:

1. Device Protection Needs: Assess the devices you want to protect. High-value items such as computers, servers, and home entertainment systems require more robust protection than lower-value devices.

2. Type of Surge Protection: There are two main types of SPDs—MOV (Metal Oxide Varistor)-based and spark gap arresters. MOV-based protectors are more common for low to medium voltage surges, while spark gap arresters are designed for high-energy surges.

3. Certifications and Standards: Look for surge protectors that meet industry standards such as UL 1449 for the United States. These certifications ensure the product's effectiveness.

4. Number of Outlets: Depending on your setup, you may need a surge protector with multiple outlets to accommodate all your devices.

5. Circuit Breaker and Reset Buttons: Some surge protectors come with a circuit breaker or reset button for added safety and convenience.

6. Warranty and Customer Support: A good warranty and reliable customer support can provide peace of mind and assistance if issues arise.

By considering these factors, you can make an informed decision when choosing a surge protective device.

What Are Some Commercial Surge Protectors?

Commercial surge protectors are designed to safeguard electrical equipment in offices, factories, data centers, and other large-scale facilities from power surges caused by lightning strikes, switching transients, or grid disturbances. These devices absorb or redirect excess voltage before it reaches sensitive systems. Here are some common types of commercial surge protectors and examples of how they are used:

1. Panel-Mounted Surge Protectors (Surge Protective Devices – SPDs)

These units are installed at the main electrical service panel or distribution boards. They protect the entire building's electrical infrastructure by diverting high-energy surges away from downstream equipment.

Common models: Schneider Electric Easy9 SPD, Siemens TPS3 Series, ABB OVR T2 Surge Arresters, Eaton SPD Series.

Applications: Factories, large offices, and retail facilities where multiple circuits feed sensitive loads.

2. Rack-Mount Surge Protectors

Used primarily in server rooms, data centers, and telecommunication setups, rack-mount protectors integrate into standard 19-inch racks. They often include EMI/RFI noise filtering and multiple power outlets.

Common models: Tripp Lite ISOBAR Rackmount Series, APC SurgeArrest Rackmount, CyberPower Professional Rackmount Surge Protectors.

Applications: Servers, network switches, audio/visual control systems, and communication equipment.

3. DIN-Rail Mounted Surge Protectors

DIN-rail protectors are compact SPDs designed for control panels and industrial automation systems. They fit neatly alongside relays and breakers in distribution enclosures.

Common models: Phoenix Contact VALVETRAB, Schneider A9L Series, OBO Bettermann V20 Series, Legrand DX3 SPD.

Applications: PLCs, motor control centers, HVAC systems, and process control equipment.

4. Plug-In and Point-of-Use Surge Protectors

These are the familiar power strip–type surge suppressors used at the device level. In commercial settings, heavy-duty versions are preferred, featuring high joule ratings and robust casings.

Common models: Belkin Commercial Surge Protector, Tripp Lite ISOBAR Ultra, APC SurgeArrest Performance Series.

Applications: Office computers, printers, POS systems, and laboratory equipment.

5. Coaxial and Data Line Surge Protectors

Not all surges enter through power lines—many come via communication or signal cables. Coaxial and Ethernet surge protectors prevent voltage spikes from damaging network equipment, CCTV cameras, and routers.

Common models: APC PNET1GB for Ethernet, PolyPhaser IS-50 Series for coaxial lines, Transtector Ethernet Surge Protectors.

Applications: Security systems, broadcast facilities, and communication networks.

6. Whole-Building Surge Protection Systems

In large commercial or institutional settings, a tiered protection system is often used—combining main panel SPDs, sub-panel protection, and point-of-use devices. This approach ensures a layered defense against both external and internal surge events.

Manufacturers offering full-system solutions: Schneider Electric, Eaton, ABB, Legrand, and Siemens.

What Do I Need a Universal Surge Protection Device for?

A universal surge protection device is essential for several reasons:

All-In-One Protection: Universal surge protectors can safeguard a wide range of devices, from small appliances to sensitive electronics, providing a comprehensive solution.

Versatility: They are designed to work with different types of power outlets and can be used in various settings, from home to office environments.

Convenience: With multiple outlets and often additional features like USB charging, a universal surge protector can simplify your power management.

Safety: They help prevent damage to your devices from voltage surges, which can be costly to repair or replace.

Peace of Mind: Knowing your valuable electronics are protected from potentially damaging surges can provide reassurance, especially in areas prone to severe weather or unstable power grids.

Investing in a universal surge protection device is a practical step towards safeguarding your electronic assets and ensuring their longevity.

Choosing the right surge protective device involves understanding your protection needs, evaluating different types of SPDs, and considering the features and reliability of commercial options. A universal surge protection device offers convenience, versatility, and peace of mind, making it an essential addition to any home or office setup.
