Hager MBN316 3-Pole 16A B-Curve 6kA Miniature Circuit Breaker, 3 Module Width

With a short-circuit breaking capacity of 6 kA and a B-curve tripping characteristic, the Hager MBN316 delivers reliable protection for cables and equipment in residential and commercial installations.

Overview

The Hager MBN316 is a 3-pole miniature circuit breaker (MCB) rated at 16 A, designed for DIN rail mounting. It operates at 230/400 V AC and 50/60 Hz, making it suitable for a wide range of three-phase circuits. The breaker features screw terminals capable of accepting rigid conductors up to 25 mm² and flexible conductors up to 16 mm², with connection possible from both top and bottom.

What stands out

• 3-pole design for three-phase protection
• B-curve for general purpose circuits with moderate inrush currents
• 6 kA breaking capacity for safe interruption of short-circuit currents
• Compact 3-module width (52.5 mm) saves space on the DIN rail
• High electrical endurance of 10,000 cycles and mechanical endurance of 20,000 cycles
