## Summary description

Simet SM20C/1-275 is a 1-pole surge arrester designed for protection of low-voltage electrical installations up to a 275 V system. With a rated impulse current capability of 20 kA, it reduces transient overvoltages caused by lightning or switching events. Intended for mounting in distribution boards, it protects sensitive equipment and prolongs service life of electrical devices.

## Long description

Simet SM20C/1-275 is a one-pole surge arrester designed for use in low-voltage electrical installations up to a 275 V system. It provides transient overvoltage protection by diverting surge energy away from connected equipment during lightning strikes or switching events. The device is intended for mounting in distribution boards and is suitable for protecting sensitive electronics, control devices and household or industrial electrical loads.
Advantages
The surge arrester offers a rated impulse current capability of 20 kA, ensuring controlled discharge of high-energy transients. Its single-pole design simplifies installation in single-phase circuits and saves space inside distribution panels. The unit reduces the risk of equipment failure and can contribute to longer service life of downstream devices without requiring complex configuration or maintenance.
Suitable for
 Protection of single-phase distribution boards in residential or commercial installations
 Safeguarding household appliances and consumer electronics
 Protection of control and automation equipment in light industrial applications
 Use in electrical panels where surge protection up to 275 V is required
Key specifications
 Number of poles: 1-pole
 System nominal voltage: up to 275 V
 Rated impulse current (Iimp): 20 kA
 Intended mounting: distribution board / DIN-rail compatible
 Primary function: transient overvoltage diversion and protection of connected loads
How to use
Mount the surge arrester inside the distribution board in accordance with local electrical codes and the manufacturer's mounting instructions. Connect the device to the phase conductor and to the appropriate grounding/earthing conductor to ensure that surge currents are safely diverted to ground. Verify that the system voltage does not exceed the specified 275 V rating and that the wiring and protective devices are suitable for the expected load. After installation, routinely inspect the arrester and connections for signs of damage or degradation following any major transient events.
Usage recommendations
Ensure correct earthing of the installation for optimal performance and safety. Use the surge arrester as part of a coordinated protection scheme together with upstream and downstream overcurrent and overvoltage protective devices. Replace the arrester if it shows visible signs of damage or if it has operated under extreme surge conditions.
