4-channel 24 VDC breaker with adjustable 2–10 A per channel, remote control, IP20 housing, DIN-rail mount.
4-channel electronic circuit breaker for 24 VDC distribution, with adjustable per-channel output current from 2 to 10 A, remote reset/control, and communication signaling. The device accepts 18 to 30 VDC input, provides 4 x 24 VDC outputs, includes selectable trip behavior from 16 ms to 100 s, and is DIN-rail mounted in a compact 45 mm x 90 mm housing. The official datasheet lists IP20 protection, Class III insulation, 0.5 kV isolation between connectors and housing, and a 170 g mass.

Protects multiple downstream 24 VDC branches in one compact DIN-rail module while maintaining per-channel adjustability for mixed load sizes.
Prevents a single faulted branch from collapsing the entire 24 VDC supply bus.
Fits control panels feeding solenoids, relays, and small DC actuators because each channel can be set independently from 2 to 10 A with load-dependent trip timing.
Matches protection to varying inrush and operating currents across different loads.
Supports remotely resettable 24 VDC auxiliary power segments using the S1 input and active status outputs for PLC diagnostics.
Enables fast fault recovery and centralized monitoring without opening the panel.
