No. Never perform a Hi-Pot test on an installed SPD. The SP Series contains surge protection components that can be affected by high-voltage testing. Follow the applicable electrical safety procedures and the manufacturer's installation instructions. Recommended Models / Applications: All SP Series models - applicable during installation, commissioning, and electrical system testing.

The SP Series terminals accept #12 AWG (4 mm²) to #2 AWG (35 mm²) solid conductors, or up to #4 AWG (25 mm²) stranded conductors. The recommended terminal tightening torque is 2 Nm. Recommended Models / Applications: All SP Series models - DIN-rail installation in commercial and industrial distribution systems.

Before installation, verify the SPD model, system voltage, wiring configuration, and connection terminals. The electrical supply must be completely switched off and locked out before installation or servicing. The neutral and ground connections must also be reliably connected. Recommended Models / Applications: All SP Series models - installation by qualified electrical personnel in accordance with applicable [...]

The SP Series can be installed at the main distribution board or downstream sub-distribution panels. The SPD is connected in parallel with the electrical system and should be installed as close as practical to the equipment or distribution point being protected. Recommended Models / Applications: SP Series - main distribution boards, sub-distribution panels, commercial buildings, and [...]

The SP Series SPD is designed to protect electrical systems and connected equipment against transient overvoltages caused by direct or indirect lightning and power system switching events. It is suitable for commercial and industrial electrical installations. Recommended Models / Applications: SP Series - suitable for service entrances, point-of-entry applications, and downstream distribution or sub-panels.

SPD installation is a hazardous activity. The following safety rules must be strictly observed: De-energize the Circuit: ALWAYS disconnect and lock out all power sources to the panel before installation or servicing. Never work on live equipment. Qualified Personnel Only: Installation must be performed by a qualified electrician or trained personnel in compliance with all national and local electrical codes. [...]

VPR (Voltage Protection Rating): This is a key performance indicator defined by the UL 1449 standard. A lower VPR value signifies better clamping performance, meaning the SPD can limit the surge voltage to a lower level, providing superior protection for downstream sensitive electronic equipment. For example, for a 120/240V system, a lower L-N VPR (e.g., 600V) is [...]

PTMOV (Protected Thermally MOV) is Prosurge's patented technology—a Metal Oxide Varistor with an integrated thermal protection mechanism and arc extinguish device. Its core advantages are: Superior Safety: Traditional MOVs can overheat and catch fire when subjected to continuous overvoltage or surges exceeding their rating. The PTMOV incorporates an internal thermal disconnector that swiftly and safely disconnects the MOV [...]

"Full Mode Protection" means the SPD provides surge suppression between all possible combinations of conductors in the power system, including: L-N (Line-to-Neutral) L-G (Line-to-Ground) N-G (Neutral-to-Ground) L-L (Line-to-Line, for split-phase or three-phase systems) Implementing full mode protection is a best practice because transient overvoltages can occur between any conductor combination. Most Prosurge panel SPD series (e.g., PSP C, HPSP, PS) offer a [...]

According to the ANSI/UL 1449 5th Edition, the installation location differentiates Type 1 and Type 2 SPDs: Type 1 SPD: Designed for installation between the secondary of the service transformer and the line side of the service equipment overcurrent device. This includes the meter socket or the main breaker's line side. They are intended to be installed without [...]
