SP240 Series DIN Rail Surge Protection Device for Single-Phase Power Lines
The SP240 Series DIN Rail Surge Protection Device (SPD) is designed for 240V single-phase power lines, with seven models offering maximum discharge current ratings from 10kA to 120kA.
The SP240 Series provides surge protection for single-phase AC power distribution systems. The devices are connected in parallel with the protected loads to suppress and discharge transient overvoltage and surge currents.
The original technical brochure lists Type D, Type C and Type B protection classifications for 240V AC power systems. Available models range from SP240-10KA/2 to SP240-120KA/2.
The series uses a modular design with a visual status indicator, thermal breaker and built-in overcurrent fuse protection. The indicator displays green under normal operating conditions and red when deterioration is detected.

TECHNICAL DETAILS
SP240 Series Discharge Current Specifications
Nominal discharge current (In) and maximum discharge current (Imax) are specified separately, both using an 8/20µs surge current waveform.
| Model | In (8/20µs) | Imax (8/20µs) | Up |
|---|---|---|---|
| SP240-10KA/2 | 5kA | 10kA | ≤1.0kV |
| SP240-20KA/2 | 10kA | 20kA | ≤1.2kV |
| SP240-40KA/2 | 20kA | 40kA | ≤1.5kV |
| SP240-60KA/2 | 30kA | 60kA | ≤2.0kV |
| SP240-80KA/2 | 40kA | 80kA | ≤2.2kV |
| SP240-100KA/2 | 50kA | 100kA | ≤2.5kV |
| SP240-120KA/2 | 60kA | 120kA | ≤2.5kV |
In = Nominal Discharge Current; Imax = Maximum Discharge Current; Up = Voltage Protection Level. All values are from the original manufacturer specification.

INSTALLATION INFORMATION
DIN Rail Mounting and Status Checking
The original installation instructions specify mounting the unit on a 35mm DIN rail and connecting it in parallel with the incoming power lines in a distribution board.
The incoming power source must be isolated before electrical connections are made. Live, neutral and protective earth connections must follow the terminal markings and original installation diagram.
The manufacturer recommends regular status checks. A green indicator denotes normal condition, while a red indicator means the device has deteriorated and requires replacement.
