Residual current circuit breaker, 1P+N, B characteristic, 16A, 6kA, 10mA, Type A, instantaneous DS201 B16 A10 2CSR255180R0165

Residual Current Circuit Breaker (RCCB) DS201 B16 A10 is a reliable protection for electrical installations, combining the functions of an overcurrent circuit breaker and a residual current device. The device is designed to protect single-phase circuits against the effects of overloads, short circuits, and leakage currents. It is characterized by high efficiency and a quick response to hazards, ensuring user safety.

Protection and Application

This 1P+N circuit breaker with characteristic B is perfect for use in home installations and public buildings. Characteristic B means that the circuit breaker reacts quickly to short-term overloads, but is less sensitive to short current surges during the starting of devices with motors – which is particularly important when protecting lighting circuits or power outlets for household appliances. The differential capability of 10mA (sensitivity A) provides protection against electric shock, and the high short-circuit breaking capacity of 6kA guarantees effective disconnection of the circuit in the event of a failure.

Construction and Installation

The DS201 B16 A10 circuit breaker has a width of 2 modules, which makes it easy to install in a distribution board. The cross-section of the connected multi-core cable up to 16mm² provides flexibility when choosing cables. The device operates at temperatures from -25°C to 55°C, allowing it to be used in various environmental conditions. Additionally, simultaneous disconnection of the N pole increases safety in the event of a short circuit or leakage current. The degree of protection IP20 provides protection against accidental contact, but does not protect against the effects of water – therefore, the device should be installed in dry rooms.
