A Type 2 Surge Protection Device (SPD), also known as a Class II surge protective device or Type 2 surge arrester, is designed to provide secondary-stage protection. It is typically installed at distribution boards or sub-panels to safeguard electrical systems from transient overvoltages caused by indirect lightning strikes and switching surges. As a reliable AC power surge protector Type 2, it works in coordination with Type 1 SPDs to ensure comprehensive protection.
Choose a Type 2 SPD lightning arrester to secure your distribution board and electrical infrastructure with trusted, tested overvoltage protection.

For in-depth guidance on selecting the right device, check out our detailed how to select Type 2 surge protective device resource.
This standard compliance and robust design make the DIN rail surge protection device a trusted solution across different network types and installation setups.
Type 2 SPDs are ideal for protecting commercial building distribution boards, ensuring sensitive equipment stays safe from sudden power spikes. In industrial facilities and machinery panels, these devices guard critical machinery from damaging surges, helping avoid costly downtime. For residential homes, Type 2 surge arresters provide reliable protection against everyday power surges, enhancing appliance lifespan and safety.
Server rooms and telecom equipment also benefit greatly from Class II surge protective devices, where maintaining uninterrupted operation is crucial. When used alongside Type 1 SPDs, which handle direct lightning strikes, Type 2 SPDs offer a layered, coordinated defense for comprehensive indirect lightning protection.
For tailored surge protection solutions suited to distribution boards and sub-panels, check out GANDIAN’s Type 2 surge protection device range.
A Type 2 SPD primarily relies on its Metal Oxide Varistor (MOV) core to divert surge currents safely away from your electrical system. When a voltage spike occurs—often due to indirect lightning strikes or switching surges—the MOV quickly changes its resistance, channeling the excess energy to ground and keeping your equipment safe.
For higher energy surges, many Type 2 surge arresters include an optional Gas Discharge Tube (GDT). This component activates under extreme surge conditions, handling large pulses without damage, extending the device’s lifespan and reliability.
The surge current enters the SPD through the input terminals and follows the protection path created by the MOV (and GDT if installed). This pathway reduces the voltage to a safe level (Voltage Protection Level, Up) before passing the current through thermal disconnects or short-circuit protection to eliminate threats to downstream devices.
This layered protection mechanism makes the Class II surge protective device effective for secondary-stage protection in your distribution boards, providing a robust barrier against overvoltage events without downtime or damage.
For more details on coordinated surge protection, pairing your Type 2 SPD with GANDIAN Type 1 SPDs offers full-spectrum voltage safeguard for both primary and secondary defense stages.
Proper installation of your Type 2 surge protection device (SPD) is key to ensuring reliable secondary surge protection for your distribution boards or sub-panels. Here’s a straightforward guide to get it right.
Install the Type 2 SPD as close as possible to the main distribution board or sub-panel where surge protection is required. This location minimizes cable length and reduces the risk of transient overvoltages reaching sensitive equipment.
For detailed wiring diagrams aligned with your system’s configuration, consult the manufacturer’s installation manual or related DIN rail mounting products such as DC MCCB solutions for reference on panel setups.
To protect both your Type 2 SPD and the electrical system, install fuses or circuit breakers upstream as required. These devices should match the SPD’s rated current capacity to prevent damage from short circuits or overloads. For guidance on fuse ratings and backup protection, you can refer to our fuse ratings explained guide.
By following these steps, you’ll ensure your Type 2 surge arrester performs optimally, providing lasting protection against surge events in your installation.

| Question | Answer |
|---|---|
| What’s the difference between Type 1 and Type 2 SPDs? | Type 1 SPDs handle direct lightning strikes and are installed at the main incoming board. Type 2 SPDs are for secondary stage protection, typically in distribution boards or sub-panels, protecting against residual surges and switching surges. |
| Can a Type 2 SPD handle a direct lightning strike? | No, Type 2 surge arresters are designed for indirect lightning protection and high-energy surges but not direct strikes. For direct strikes, a Type 1 SPD is required. |
| How do I select the right Imax for my Type 2 SPD? | Choose the Imax value based on the expected surge current in your area and system size. Higher Imax (e.g., 40kA surge protector) means better capacity to handle large surges. Balance with cost and space. |
| What does the status indicator on a Type 2 SPD show? | The visual status indicator signals whether the SPD is active and functioning correctly. A green or normal color means good status; red or off usually means replacement is needed. |
| Is remote signaling available on Type 2 SPDs? | Yes, many Type 2 SPDs include optional remote alarm contacts to alert facility managers of device failure, enabling proactive maintenance. |
