Manufacturer part number: S 304 D20 TX
A circuit breaker is both a circuit-breaking device that can make, withstand and break currents whose intensity is at most equal to its rated current (In), and a protection device that can automatically break overcurrents which generally occur following faults in installations. The choice of a circuit breaker and its characteristics depends on the size of the installation.
Legrand combines innovation with user-friendly functionality, making it a top choice for professional electricians and panel builders. Legrand products are known for high performance, reliability, and modern design. Legrand offers a wide range of modular devices, circuit breakers, RCDs, industrial switches, and electrical enclosures-suitable for residential, commercial, and industrial applications.
