Product Description

The SITOP SEL1400 (6EP4437-7EB00-3CX0) is a 4-channel selectivity module with limiting characteristic for 24 V DC, distributing power to up to four load branches with individually adjustable 2-10 A per channel.

Limiting Characteristic

Unlike conventional switching selectivity modules, the SEL1400 uses a power-limiting design that prevents the 24 V bus from dropping below 20 V during overload or short-circuit faults. This protects sensitive electronic loads such as PLCs, industrial PCs, and network equipment from unexpected reset or damage.
