Product information

Description

The ABB S203-B16 is a professional-grade 3-pole miniature circuit breaker engineered to provide robust protection for electrical circuits. Designed for both residential and industrial environments, this device effectively safeguards systems against overcurrent and short-circuit damage. It utilizes a dual-tripping mechanism, combining thermal protection for overloads and electromechanical protection for short circuits, ensuring consistent operational stability and safety in power distribution networks.

Advantages

This circuit breaker stands out for its high reliability and current-limiting capabilities, which help minimize the impact of electrical faults on downstream equipment. Its compact design allows for efficient use of space within distribution boards, and the ability to mount bottom-fitting auxiliary contacts further optimizes installation space by up to 50 percent. The device is built to meet rigorous international standards, ensuring long-term durability and performance in diverse electrical applications.

Suitable for

Residential electrical installations
Commercial power distribution systems
Industrial machinery and equipment protection
General electrical circuit safety management

When it may not be suitable

This device is not intended for use in DC circuits unless specifically rated for such applications, as it is designed for AC power distribution. It may also not be suitable for systems requiring higher breaking capacities than those specified for this model.

Rated current: 16A
Rated voltage: 230/400V AC
Tripping characteristic: B
Frequency: 50/60 Hz

Compliance: IEC/EN 60898-1, IEC/EN 60947-2, UL1077, CSA 22.2 No. 235

How to use

The ABB S203-B16 should be installed by a qualified electrician into a standard DIN-rail distribution board. Ensure that the power supply is disconnected before beginning the installation. The device is snapped onto the rail, and the input and output cables are securely connected to the terminals. Once installed, the breaker can be switched on to energize the circuit. Regular visual inspections are recommended to ensure the terminals remain tight and the device is free from physical damage.

What to consider before purchase

Verify that the 16A rated current matches your circuit requirements.
Ensure the 3-pole configuration is appropriate for your specific electrical load.
Check that the available space in your distribution board accommodates the dimensions of the unit.
Confirm compatibility with existing DIN-rail mounting systems.

Usage recommendations

Always ensure that the total load on the circuit does not exceed the 16A rating to prevent nuisance tripping. If the breaker trips, investigate the cause of the overload or short circuit before resetting the switch.
