Residual current circuit breaker, 1P+N, B characteristic, 16A, 6kA, 30mA, Type A, instantaneous DS201 B16 A30 2CSR255180R1165

Safety and Reliability in Your Electrical Installation

This 1P+N residual current circuit breaker (RCCB) is a key element in protecting electrical installations in residential, commercial, and industrial buildings. It provides comprehensive protection against the effects of overloads, short circuits, and dangerous leakage currents. Its design, based on proven ABB technology, guarantees long-lasting and trouble-free operation.

Characteristics and Application

The DS201 B16 A30 circuit breaker with characteristic B is an ideal solution for circuits with devices with moderate inrush current. Characteristic B allows it to react more slowly to short current surges, so it tolerates the starting of devices with a motor – pumps, fans or air conditioning. The residual current protection with a sensitivity of 30mA (type A) effectively protects users from electric shock in the event of insulation failure.

• Overload protection: Protects the circuit from overload – like most circuit breakers in this class.
• Short-circuit protection: Quickly disconnects the circuit in the event of a short circuit, minimizing the risk of damage to equipment and fire.
• Electric shock protection: Detects and disconnects the circuit in the event of a leakage current, protecting users from electric shock.
• Versatile application: It will work in lighting circuits, socket circuits and powering household appliances.

Construction and Installation

The circuit breaker is designed for easy mounting on a DIN rail (2 module width). Its compact dimensions (depth 69 mm) allow installation even in limited space of the distribution board. The solid construction ensures durability and resistance to mechanical damage. The cross-section of the connected multi-wire cable is from 0.75 to 16 mm², which provides great flexibility in cable selection. The rated short-circuit breaking capacity is 6kA, and the impulse withstand voltage Uimp is 4kV – these parameters guarantee safe operation in various operating conditions.

The circuit breaker is designed to operate in ambient temperature from -25°C to +55°C and has a protection degree of IP20 – which means protection against touching with a finger and solid objects larger than 12.5 mm. It meets the requirements of EN 61009-1 and IEC 60947-2 standards, which confirms its compliance with the highest safety standards.
