## Summary description

Legrand ON300 C is a four-pole surge protector rated for 20 kA (per mode) with a nominal discharge voltage of 1.2 kV. Designed to protect electrical installations and connected equipment from transient overvoltages, it is suitable for residential and light commercial applications. The device mounts in distribution boards to reduce risk of damage from lightning-induced and switching surges.

## Long description

Legrand ON300 C 4P 20 kA 1.2 kV is a four-pole surge protector designed to be installed in electrical distribution boards to protect installations and connected devices from transient overvoltages. The device provides coordinated protection for all phases and neutral, limiting peak voltages generated by lightning strikes or switching events. It is intended for residential and light commercial electrical systems where compact DIN-rail mounting and reliable overvoltage suppression are required.
Advantages
The surge protector offers a 20 kA nominal discharge capability per mode and a nominal discharge voltage of 1.2 kV, providing robust suppression of transient overvoltages. Its four-pole configuration ensures simultaneous protection of phase conductors and neutral, helping to prevent differential and common-mode surges from damaging sensitive equipment. Designed for installation in distribution boards, the unit has a compact form factor and integrates with standard electrical protection schemes. Built-in indicators and replaceable elements support maintenance and help ensure continued protective performance.
Suitable for
Residential electrical panels and home distribution boards
Small offices and light commercial electrical installations
Protection of consumer electronics, IT equipment and HVAC control circuits
Systems requiring coordinated phase-to-neutral and phase-to-phase surge protection
Key specifications
Configuration: four-pole (3 phases + neutral)
Nominal discharge current per mode: 20 kA
Nominal discharge voltage (Voltage protection level): 1.2 kV
Protection type: transient overvoltage/surge suppression for lightning and switching transients
Mounting: DIN-rail installation in distribution boards
Application: residential and light commercial electrical systems
Indicators: status/health indication and replaceable protection modules
How to use
Install the surge protector inside the distribution board on the DIN rail according to local wiring regulations and the manufacturer's installation instructions. Connect the three phase conductors and neutral to the corresponding terminals, and ensure a correct and low-impedance connection to the building earthing system. Verify polarity and phase sequence where required, and coordinate with upstream overcurrent protection devices. After installation, check the built-in indicators to confirm the device is operational and perform periodic visual inspections as part of routine electrical maintenance.
Usage recommendations
Use this surge protector as part of a layered protection strategy combined with upstream main surge arresters and appropriate circuit breakers. Ensure earthing and bonding meet applicable standards to maximize performance. Replace protective modules promptly if indicators show end-of-life or fault conditions to maintain continuous surge protection.
