## Long description

SIMTEC SM20C/4-275 C is a four-pole surge protector by Simet designed to limit transient overvoltages in low-voltage power systems. With a nominal discharge current rating of 20 kA and Type C protection at a 275 V reference, this unit is intended to reduce the risk of damage to downstream electrical and electronic equipment. The device features a compact form factor for DIN-rail mounting and a visual fail-safe indication to show protection status and simplify maintenance.
Advantages
The SM20C/4-275 C provides coordinated overvoltage suppression across all four poles, ensuring balanced protection for three-phase systems with neutral. Its 20 kA nominal discharge capacity addresses a wide range of transient events while maintaining a compact footprint for installation in distribution boards. The built-in visual indication enables quick verification of the protector’s condition without additional testing equipment. DIN-rail mounting and standard dimensions allow straightforward integration into typical low-voltage panels.
Suitable for
Residential distribution boards and main service entrances
Commercial electrical panels in offices, retail and hospitality
Light-industrial installations and small manufacturing units
Protection of sensitive downstream equipment such as control units, PLCs and communication devices
Key specifications
Number of poles: 4 (three phases + neutral)
Protection type: Type C overvoltage protection
Nominal discharge current (In): 20 kA
Reference voltage: 275 V
Mounting: DIN-rail compatible
Indication: Fail-safe visual status indicator
How to use
Install the SM20C/4-275 C on a standard DIN rail inside the distribution board according to the electrical wiring diagram and applicable installation rules. Connect the three phase conductors and neutral to the corresponding terminals, and ensure proper earth/grounding of the installation per local regulations. Verify the device’s visual status indicator after energizing the system and incorporate the protector into routine panel inspections to confirm ongoing operation.
Usage recommendations
Position the surge protector as close as practical to the incoming supply or main distribution bus to minimize lead length and achieve optimal protection performance. Regularly inspect the visual indication and replace the unit if it shows a failed status or after a major surge event. Ensure coordination with upstream and downstream protective devices and consult applicable standards and a qualified electrician for correct selection and installation.
