Hager SBN316 SBN Load Break Switch 3P 16 A DIN Rail

The Hager SBN316 is a 3-pole load break switch rated at 16 A and 400 V AC for DIN rail installation in modular distribution systems. It provides simultaneous disconnection across all three poles via three make contacts and occupies just 2 DIN modules (35 mm wide). With an impulse withstand voltage of 4 kV and insulation voltage of 440 V, it meets IEC 60947-3 requirements for reliable circuit isolation.
