## Summary description

QOLTEC 52588 is an AC surge protector with 4 poles, rated for 420 V and classified as Type 2 (T2). It protects electrical installations and connected equipment from transient overvoltages. Suitable for distribution boards and commercial or residential electrical systems, it reduces risk of damage from lightning-induced surges and switching events and simplifies installation in multi-phase circuits.

## Long description

QOLTEC 52588 AC 4P 420V T2 C is a 4-pole Type 2 surge arrester designed to limit transient overvoltages in AC distribution systems. Intended for installation on distribution boards, the device provides coordinated protection for multi-phase circuits and helps safeguard electrical installations and connected equipment from lightning-induced surges and switching transients. The compact form factor and standard mounting options make integration into commercial and residential panels straightforward.
Advantages
The surge protector offers four-pole protection at a nominal voltage suitable for common three-phase systems with neutral, enabling simultaneous protection of all live conductors and neutral. As a Type 2 device, it is engineered to handle switching surges and residual lightning energy downstream of the main earthing and primary protection. Its design simplifies wiring in multi-phase installations and reduces the risk of equipment failure or insulation breakdown caused by transient overvoltages.
Suitable for
 Distribution boards in residential buildings
 Commercial electrical panels and small industrial installations
 Protection of motors, control equipment and electronic devices connected to three-phase systems
 Retrofit projects where coordinated Type 2 protection is required
Key specifications
 Configuration: 4-pole surge arrester (three phases plus neutral)
 Nominal system voltage: compatible with 420 V class AC systems
 Protection class: Type 2 (designed for transient overvoltages downstream of main protection)
 Intended mounting: distribution board / DIN-rail compatible form factor
 Primary function: reduce transient overvoltages from lightning-induced surges and switching events
How to use
Install the surge arrester on the distribution board close to the incoming supply and as near as practical to sensitive equipment to minimize lead length. Connect the three phase conductors and neutral to the designated terminals, and ensure a low-impedance equipotential bonding to the grounding/earthing system. Verify that upstream protection devices and earthing arrangements are coordinated with Type 2 protection before commissioning. Periodically inspect the unit and associated connections as part of routine electrical maintenance.
Usage recommendations
Use this Type 2 surge arrester as part of a layered protection scheme: combine it with upstream main protection and proper earthing to achieve effective transient suppression. Avoid installing the device without verified grounding and ensure any replacement follows the original device’s electrical characteristics and mounting requirements.
