Core Features & Market Positioning

The ABB S201-B16 stands out due to its combination of reliable performance and ease of installation. Its current limiting design quickly interrupts fault currents, minimizing damage to downstream equipment. The device features a patented connection terminal with a pressure plate, allowing for easy and secure wiring with conductors up to 35 mm². Its compact design, with a width of only one module (17.5mm), saves valuable space in electrical panels. The S201-B16 is suitable for use with or without additional accessories such as auxiliary switches.

Key Application Scenarios

This ABB 16A circuit breaker is commonly used for protecting lighting circuits and socket outlets in residential buildings. It is also suitable for protecting individual appliances with moderate starting currents, such as refrigerators or washing machines. In commercial settings, the S201-B16 can be used for protecting branch circuits supplying office equipment and lighting. Industrial applications include protection of control circuits and small machinery.

Practical System Integration Guidance

The ABB S201-B16 is designed for easy installation on standard DIN rails. It can be fed from either direction. The optimized quick fastening allows easy removal and insertion of the devices when combined with the System pro M compact busbar system. The connection opening for conductors is located above the connection opening for the busbar to improve visibility during wiring. The S201-B16 can be combined with auxiliary contacts, shunt trips, and undervoltage releases for enhanced functionality.

Operation and Risk Mitigation

The S201-B16 provides reliable protection against overloads and short circuits. In case of an overload, the thermal tripping mechanism will activate, disconnecting the circuit after a certain time. In the event of a short circuit, the electromechanical tripping mechanism will immediately interrupt the circuit. The red ON / green OFF indicator provides a clear visual indication of the switch position. The device has an IP20 degree of protection, protecting against contact with live parts and solid objects larger than 12mm.

Concluding Section (FAQs)

Q1: What is the breaking capacity of the ABB S201-B16?

The S201-B16 has a breaking capacity of 6 kA according to IEC/EN 60898-1. This refers to its ability to safely interrupt a short-circuit current. It also has a 10kA breaking capacity according to IEC/EN 60947-2.
