Product information

Description

The ABB S203-C16 is a robust 3-pole miniature circuit breaker engineered to provide reliable protection for electrical circuits. Designed for high performance, this device effectively safeguards industrial and residential installations by monitoring current flow and interrupting power in the event of an overload or short circuit. With a rated current of 16A and an operating voltage of 440V, it ensures consistent operational stability and safety for your electrical infrastructure.

Advantages

This circuit breaker utilizes advanced current-limiting technology to minimize the energy let-through during fault conditions, which helps protect downstream equipment from damage. It features a dual-tripping mechanism that combines a delayed thermal element for overload protection with an electromechanical element for rapid short-circuit response. The compact design allows for efficient space utilization within distribution boards, and the ability to mount bottom-fitting auxiliary contacts further optimizes installation space by up to 50 percent.

Suitable for

Residential electrical distribution systems
Commercial building power management
Industrial machinery and control panels
Protection of lighting and heating circuits

This device may not be suitable for applications requiring a different tripping characteristic, such as B, D, K, or Z, which are designed for specific load types like high-inrush current motors or sensitive electronic equipment. It is also not intended for use in circuits exceeding its rated current capacity of 16A or voltage limits.

Key specifications

Number of poles: 3
Rated current: 16A
Rated voltage: 440V AC
Tripping characteristic: C
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-C16 is designed for DIN-rail mounting within a standard electrical distribution enclosure. Installation should be performed by a qualified electrician in accordance with local electrical codes. Ensure that the supply power is disconnected before mounting the device. Once securely snapped onto the rail, connect the incoming supply cables to the top terminals and the outgoing load cables to the bottom terminals, ensuring all connections are tightened to the manufacturer's specified torque settings.

What to consider before purchase

Verify that the 16A rating matches your circuit load requirements.
Ensure the 3-pole configuration is appropriate for your three-phase electrical system.
Check that the C-type tripping characteristic is suitable for your specific application.
Confirm that the enclosure has sufficient space for the device and potential auxiliary contacts.

Usage recommendations: Regularly inspect the circuit breaker for signs of wear or thermal damage. Test the device periodically to ensure the mechanical tripping mechanism remains functional. Do not attempt to repair or modify the internal components of the circuit breaker, as this will void the warranty and compromise safety.
