Abb Residual current circuit breaker 2P 20A 6kA C A 300mA 2M
The residual current circuit breaker offers dual protection:
-
Magnetothermal, which intervenes in the event of overloads and short circuits up to 6kA
-
Differential, which protects against current leakage above 300mA, preventing the risk of fire due to high leakage
Curve C provides optimal protection for circuits with moderate loads, such as lighting, electrical outlets, and small motors.
Versatility and Applications
Due to its compliance with safety standards and its ability to operate with a rated voltage of 230/440V, it is ideal for:
-
Residential installations (general system protection)
-
Commercial buildings (stores, offices, public places)
-
Industrial sector (switchboards, protection of circuits with high loads)
The 300mA differential protection makes it particularly suitable for preventing electrical fires in environments with older installations or where current leakage could pose a danger.
Compact Design and Simple Installation
The switch features a compact design with a width of 2 DIN modules (35mm), facilitating installation in electrical panels.
The IP20/IP40 degree of protection ensures resistance to dust and external agents, while the wide operating temperature range (-25/+55 degrees ) ensures reliable performance even under harsh conditions.
