Siemens SITOP SEL1400 Selectivity Module DC 24 V 4 Outputs 40 A 6EP4437-7EB00-3DX0

The Siemens SITOP SEL1400 selectivity module ensures reliable selective overload and short-circuit protection for DC 24 V power distribution systems. With four individually adjustable outputs (0.5 A to 10 A each) and a total output current of up to 40 A, it provides precise fault isolation to minimize downtime. Ideal for industrial control cabinets, it features electronic selective protection, collective signaling contacts, and LED status indicators per channel. The module supports remote reset and diagnostic interface for SITOP Manager, enabling efficient monitoring and maintenance.

Advantages

Selective fault isolation prevents total system shutdown; adjustable output currents allow flexible configuration; remote reset and diagnostics reduce manual intervention; compact DIN rail mounting saves space; comprehensive approvals ensure global applicability.
