This circuit breaker provides overcurrent and short-circuit protection for a single-phase-plus-neutral circuit, rated at 16A with a C-curve trip characteristic. The C-curve makes it suitable for circuits with moderate inrush currents, such as those supplying inductive or lightly capacitive loads. Its modular format allows mounting on standard DIN rail within control panels and distribution boards.
