ABB DS201 Series RCBO, 20A Current Rating, 30mA Trip Sensitivity - 2CSR255180R1204 DS201 C20 A30

This RCBO is designed to offer effective protection for single-phase circuits against overloads and short circuits, making it a critical component for safety in electrical installations. The device is compact, with dimensions of 69mm x 35mm, and is intended for DIN rail mounting, providing a clean, organised solution for electrical distribution boards. Its robust features ensure reliable performance within a rated AC voltage of 240V.

Features & Benefits

• Provides short circuit protection to enhance safety

• Designed with 30 mA trip sensitivity for effective fault detection

• Features Type C tripping characteristics suited for inductive loads

• Installs easily on DIN rail for straightforward integration

• Boasts a breaking capacity of 10 kA for reliable fault interruption

• Equipped with a toggle switch for simple manual reset

Applications

• Used for protecting individual circuits in residential installations

• Suitable for commercial requiring circuit overload protection

• Ideal for use in areas where direct contact safety is essential

• Employed in electrical panels to safeguard sensitive equipment

• Utilised in environments subject to earth fault conditions

What is the significance of the 30 mA trip sensitivity in this device?

The 30 mA trip sensitivity is crucial as it helps to detect earth faults promptly, ensuring user safety by disconnecting the circuit before a potentially dangerous situation develops.

How does the breaking capacity of 10 kA benefit installations?

A breaking capacity of 10 kA means the device can handle high fault currents without sustaining damage, ensuring consistent operation during fault conditions while protecting downstream equipment.

What types of loads are suitable for a Type C tripping characteristic?

Type C tripping characteristics are suitable for circuits with inductive loads, such as motors and transformers, as they prevent nuisance tripping while offering reliable protection against overloads.

Can this device be used in harsh environmental conditions?

It is designed to operate effectively in environments with temperatures ranging from -25°C to +55°C, allowing it to function reliably across a variety of conditions.

What is the practical advantage of using DIN rail mounting for this product?

DIN rail mounting provides a secure and efficient installation method, allowing for easy assembly and disassembly in electrical cabinets, thus saving valuable time during maintenance or upgrades.
