Weidmüller 9102003500 Supplementary Circuit Breaker

Weidmüller 9102003500 is a DIN-rail mounted thermal-magnetic supplementary circuit breaker designed to protect PLC systems and automation panels from overloads and short circuits, combining a compact form factor with reliable industrial protection. This 1-pole device is rated at 15 A, offers a 400 A interrupt capacity, operates on 250 VAC or 65 VDC, and uses a screw-terminal connection with a push-button reset for straightforward wiring and reset after fault conditions. Common applications include PLC cabinets, OEM machinery, packaging lines, and process control systems, where it serves as a dedicated branch circuit and control circuit protector that enhances electrical safety, reduces downtime, and supports easy maintenance access within factory automation environments. Its DIN-rail mounting, compact footprint, and design support quick retrofits and reliable performance in factory settings, while the device's protective function targets overloads and short circuits to safeguard PLCs, power supplies, and industrial controllers. For compatibility within automation ecosystems, the Weidmüller 9102003500 is commonly replaced by similar thermal-magnetic supplementary breakers from Phoenix Contact, Siemens, and Allen-Bradley.
