Siemens SITOP SEL1400 Selectivity Module DC 24 V/8 x 2.1 A (6EP4438-7EB00-3DX0)

The Siemens SITOP SEL1400 selectivity module is a high-performance electronic protection device designed for selective overload and short-circuit protection in DC 24 V systems. It features 8 individually adjustable output channels, each capable of delivering up to 3 A, with a total output current of 24 A. This module ensures reliable power distribution and fault isolation in industrial control cabinets, preventing total system shutdowns.

Advantages

Selective fault isolation: Only the affected channel is switched off, leaving other loads operational. Adjustable current per channel from 0.5 A to 3 A allows precise protection. LED signaling per channel for quick diagnostics. Compact DIN rail mounting saves space. Wide operating temperature range from -25 °C to +70 °C ensures reliability in harsh environments.

Suitable for

• Industrial automation systems
• Machine building
• Process control
• Building infrastructure
• Any application requiring selective DC 24 V power distribution
