EATON SPD series surge protector

EATON SPD series surge protector

Product Overview

The Eaton SPD series surge protection device is the latest generation of advanced surge protection devices certified by UL 1449 5th edition. This series of products adopts thermal protection metal oxide varistor (MOV) technology and can be integrated into various types of Eaton distribution equipment, including distribution panels, switchgear, motor control centers, medium voltage switchgear, automatic transfer switches, and busbar junction boxes. In addition, the SPD series also offers a side mounted version that can be installed outside of electrical equipment.

The SPD series covers multiple surge current capacity levels from 50kA to 400kA, supports all common voltages and configurations, and offers four functional package options. Its rich features, options, and configurations ensure that users can choose the most suitable protection unit for various electrical applications, including inlet ports, distribution cabinets, distribution panels, and terminal equipment.

Core technical features

1. Thermal protection MOV technology

The SPD series uses metal oxide varistors as the core protective component and integrates thermal protection function. When MOV generates excessive heat due to abnormal overvoltage, the thermal protection device will isolate it from the circuit to ensure equipment safety and avoid the risk of thermal runaway.

2. UL 1449 5th edition certification

As the latest UL 1449 certified product, the SPD series has undergone rigorous testing, including:

Nominal discharge current (In) test: 20kA

Voltage Protection Rating (VPR) Test

Fault mode testing

Thermal stability test

3. High short-circuit current tolerance

The SPD series has a short-circuit current rating (SCCR) of 200kA, which can withstand the maximum fault current that may occur in the power system without damage.

4. Multiple surge capacity levels

Provide 9 surge current capacity levels, including 50kA, 80kA, 100kA, 120kA, 160kA, 200kA, 250kA, 300kA, and 400kA, to meet the protection needs of different risk levels.

5. Electromagnetic interference filtering

The standard type, standard type with counter, and Power Xpert SPD all have built-in EMI/RFI filters that can provide up to 50dB noise attenuation in the frequency range of 10kHz to 100MHz, improving power quality.

6. Network security authentication

The Power Xpert SPD model has passed UL 2900-1 network security standard testing, ensuring that networked devices have the necessary network security to prevent malicious attacks.

Feature Pack Options

The SPD series offers four functional packages, which users can choose according to their application needs:

1. Basic type

Remote display options

The SPD series supports remote installation of display panels, suitable for situations where devices are installed internally but require external viewing of status.

Remote display unit selection

SPD units with directory numbers ending in "B" (see directory number configuration on page 8) are suitable for remote display applications. This type of unit includes SPD host and remote display panel, and remote display cables need to be purchased separately.

Performance data and voltage protection level

ANSI/UL 1449 5th edition Voltage Protection Rating (VPR)

The SPD series provides VPR data for two installation methods:

Direct busbar installation (catalog number ending in A): Only applicable to Eaton PRL1a, 2a, 3a, and 3e distribution panels

Connected through circuit breakers (catalog numbers ending in B, C, or J): suitable for switchgear, distribution panels, switchboards, motor control centers, etc
