Suitable for
Residential electrical distribution boards
Commercial building electrical systems
Protection of three-phase circuits
Small industrial machinery and equipment
Lighting and power outlet circuits
When it may not be suitable
This device is not intended for use in high-voltage industrial power distribution networks that exceed its rated breaking capacity. It is also not suitable for environments requiring specialized protection features such as residual current detection or specific DC-only applications unless otherwise specified by the manufacturer.
Key specifications
Rated current: 16A
Number of poles: 3
Breaking capacity: 6kA
Tripping characteristic: B
Mounting type: DIN rail
How to use
The ABB SZ203-B16 should be installed by a qualified electrician in accordance with local electrical regulations. The device is designed for mounting onto a standard 35mm DIN rail within an electrical enclosure. Ensure that the supply cables are securely connected to the input terminals and the load cables to the output terminals, maintaining proper torque settings as specified. Once installed, the toggle switch can be used to manually energize or de-energize the circuit.
What to consider before purchase
Verify that the 16A rated current matches your circuit load requirements.
Ensure the 6kA breaking capacity is sufficient for the prospective short-circuit current at the installation point.
Confirm that the B-type tripping characteristic is appropriate for your specific load type.
Check the available space in your distribution board for a 3-pole device.
Usage recommendations
Regularly inspect the circuit breaker for any signs of physical damage or overheating. It is recommended to perform periodic functional checks to ensure the device remains in optimal working condition.
