Interruttore automatico magnetotermico modulare HiSmart NV821495 bipolare 16A curva C

Miniature circuit breaker HiSmart NV821495 is a 2-pole protective device rated at 16 A with a type C tripping characteristic. It provides automatic disconnection for overload and short-circuit conditions and is suitable for residential and light commercial electrical circuits. The compact breaker mounts on a standard 35 mm DIN rail and supports top and bottom connections for cables or pin-type busbars.

Advantages

The HiSmart NV821495 offers overload and short-circuit protection with a C curve characteristic for general-purpose circuits. It features an anti-mistake contact terminal block, flame-retardant and impact-resistant construction, and a visual contact position indicator (red = closed, green = open). The device complies with IEC 60898-1 / EN 60898-1 standards and provides a rated breaking capacity of 6 kA.

How to use

Install the HiSmart NV821495 on a standard 35 mm DIN rail using the fast clip device. Connect incoming and outgoing conductors to the top and bottom terminals, ensuring correct conductor cross-section up to 25 mm² or compatible busbar pins. Use the contact position indicator to verify the switch state (red = closed, green = open). The breaker will trip automatically under overload or short-circuit conditions and can be manually reset when the fault is cleared.

Recommendations

Verify that the selected 16 A C-curve breaker matches the circuit load and coordination requirements. Ensure installation and maintenance are performed by a qualified electrician and comply with local electrical codes. Do not expose the device to temperatures or conditions outside the specified ranges.
