Siemens SITOP SEL1200 Selectivity Module DC 24V 8x2-10A (6EP4438-7FB00-3DX0)

The Siemens SITOP SEL1200 selectivity module (6EP4438-7FB00-3DX0) provides selective overload and short-circuit protection for up to eight 24 V DC output circuits. Designed for DIN rail mounting, it ensures high system availability by isolating faulty channels without affecting the rest of the system.

Advantages

Electronic protection with adjustable current limits per channel (2 A to 10 A) enables precise coordination with downstream loads. Group alarm contact and LED status indicators per channel simplify diagnostics and reduce downtime.

Suitable for

• Industrial control cabinets requiring selective 24 V DC distribution
