## Summary description

ELKO-BIS ESPAC V T12 12.5/275 4+0 surge protector (MPN 10400120080) is a lightning and transient overvoltage protection device rated 12.5/275 and configured 4+0. Designed to protect electrical installations and sensitive equipment from transient voltage spikes, it is suitable for distribution boards and building power systems requiring multi-pole protection.

## Long description

The ELKO-BIS ESPAC V T12 12.5/275 4+0 surge protector is a multi-pole overvoltage protection device designed for installation in electrical distribution boards. Rated for a nominal discharge current characteristic of 12.5/275 and configured in a 4+0 arrangement, it provides transient surge suppression for the supply lines to reduce the risk of damage to wiring and connected equipment in residential and commercial buildings.
Advantages
This surge protector offers multi-pole protection suitable for three-phase systems with a neutral or for installations that require protection across multiple live conductors. The 4+0 configuration delivers coordinated suppression of transient overvoltages to help preserve the operational integrity of sensitive devices. The unit is designed for DIN-rail mounting and integration into standard distribution boards, enabling compact installation and accessibility for maintenance.
Suitable for
 Protection of distribution boards in homes, offices and small commercial buildings
 Safeguarding sensitive equipment such as servers, network devices and control systems
 Use in three-phase electrical installations requiring multi-pole surge suppression
 Installation where DIN-rail mounting and coordinated protection across conductors is needed
When it may not be suitable
This device is intended for transient overvoltage protection and should not be used as the sole means of protection against sustained overcurrent or direct lightning hits; it does not replace proper earthing, lightning rods or primary surge protection systems designed for direct strikes. For installations with special environmental requirements (for example, outdoor enclosures without appropriate IP rating) or systems that require a different protection level, an alternative or additional protection device may be required.
Key specifications
 Protection class: multi-pole 4+0 configuration
 Nominal discharge/voltage characteristic: 12.5/275
 Intended mounting: DIN-rail for electrical distribution boards
 Application: transient surge suppression for building power systems and distribution circuits
How to use
Install the surge protector on a DIN-rail inside the electrical distribution board according to local electrical codes and the manufacturer's installation instructions. Connect the incoming supply and outgoing load conductors to the corresponding terminals, ensuring correct phase and neutral identification for a 4+0 configuration. Verify that the protective earth and bonding are correctly implemented in the installation. After installation, periodically check indicator(s) or test points if provided and include the device in routine electrical maintenance inspections.
What to consider before purchase
 Compatibility with the building's supply system: three-phase vs single-phase and required pole count
 Space and mounting requirements inside the distribution board for DIN-rail installation
 Required level of surge protection for connected equipment and whether primary protection is also needed
 Local regulations and earthing/grounding arrangements
Usage recommendations
For effective protection, combine this transient surge protector with proper earthing and, where necessary, primary lightning protection. Ensure installation and periodic inspection are carried out by a qualified electrician to maintain reliable operation and safety.
