NOARK Ex9BN 1P B16 Istič, 16 A, 6 kA, charakteristika B, 1-pólový, DIN lišta

The NOARK Ex9BN 1P B16 stands apart from typical miniature circuit breakers by combining a compact single-pole design with robust 6 kA breaking capacity and precise B-curve tripping. Engineered for residential and commercial distribution boards, it delivers dependable overload and short-circuit protection for lighting and socket circuits where moderate inrush currents are expected.

Highlights

• Rated current 16 A, tripping curve B for standard loads
• Short-circuit breaking capacity Icn = 6 kA per IEC/EN 60898-1
• Single-pole (1P) module, 18 mm width, DIN rail mount
• Screw terminals accept solid or stranded conductors up to 25 mm²
• Energy limiting class 3 for enhanced safety
• Wide operating temperature range from -35 °C to +70 °C
• Mechanical endurance 20,000 cycles, electrical endurance 10,000 cycles

In daily use

Installation is straightforward on a standard 35 mm DIN rail, with clear terminal markings and a 2.5 Nm tightening torque ensuring secure connections. The toggle provides a clear visual indication of ON/OFF status, and the IP20 terminal protection (IP40 with enclosure cover) suits typical distribution board environments. The B-curve characteristic allows the breaker to handle normal switching surges without nuisance tripping, while still reacting quickly to genuine overloads and short circuits.
