Residual Current Circuit Breaker – Protection and Safety of Installations

This single-pole residual current circuit breaker, with C characteristic and a rated current of 25A, is a key element in protecting the electrical installation. It provides protection against the effects of overloads and short circuits, and also protects users from electric shock. Its compact size (2 module width) makes it easy to install in distribution boards. The device is designed to operate in AC networks with a voltage of 240V.

Functionality and technical parameters

The DS201 C25 A30 circuit breaker combines the functions of an overcurrent and residual current device, providing comprehensive protection. The C characteristic means that the circuit breaker reacts with a slight delay to short-term current surges, which is particularly important when connecting devices with electric motors or other inductive loads – it will not switch off with every device start-up. The rated short-circuit breaking capacity of 6kA guarantees effective disconnection of the circuit in the event of a serious failure. In addition, sensitivity A (30mA) ensures a quick response to leakage currents, minimizing the risk of electric shock.

• Overload protection: Protects wires and devices from damage caused by excessive current draw.
• Short-circuit protection: Quickly disconnects the circuit in the event of a short circuit, preventing fires and equipment damage.
• Electric shock protection: Detects leakage currents to earth and disconnects the circuit, protecting users from electric shock.
• Versatility: Suitable for protecting various circuits in residential and commercial buildings.
• Compact dimensions: Allow easy installation even in tight distribution boards (installation depth 69mm).
• Compliance with standards: Meets the requirements of EN 61009 and IEC 60947-2 standards, guaranteeing safety and reliability.

Installation and application

The DS201 C25 A30 circuit breaker is designed for mounting on a TH35 rail (standard mounting rail in distribution boards). The cross-section of multi-wire conductors should be in the range of 0.75 mm² to 16 mm². The device is used in electrical installations of residential, commercial and industrial buildings, where effective protection against overloads, short circuits and electric shock is required. Thanks to its versatility, it can be used to protect lighting, socket outlets and other electrical receivers. The degree of protection IP20 means protection against touching with a finger and solid objects larger than 12.5 mm – the device is intended for use in dry indoor environments.
