Product information

Description

Miniature Circuit Breaker HiSmart NV821464 1P 40A Class C is a single-pole protection device rated for 40 A with a C tripping characteristic. It is designed to protect residential and light commercial circuits from overloads and short circuits, and is intended for DIN-rail (35 mm EN 60715) installation in distribution boards.

Advantages

The device provides overload and short-circuit protection with a rated breaking capacity of 6 kA and complies with IEC/EN 60898-1 standards. Its flame-retardant housing offers high temperature resistance and impact resistance. An anti-mistake contact terminal block reduces wiring errors, and the contact position indicator shows closed (red) and opened (green) states for quick visual verification.

Suitable for

  • Protection of single-phase circuits in residential distribution boards
  • Light commercial and small industrial circuits requiring selective C-characteristic tripping
  • Motor-fed or general-purpose circuits where 40 A protection is required

How to use

Mount the HiSmart NV821464 on a 35 mm DIN rail using the fast clip device. Connect incoming and outgoing conductors to the top and bottom terminals respectively, ensuring conductor cross-sections do not exceed 25 mm² or 18-3 AWG for busbars. Verify correct polarity and secure terminals to prevent loose connections. Use the red/green contact position indicator to confirm the switch state before applying load. Do not exceed the rated current or use outside the specified temperature range.

Usage recommendations

For reliable operation, perform installation and maintenance according to applicable electrical codes and standards. Ensure the breaker is sized appropriately for the protected circuit and coordinate with upstream protective devices when necessary. Inspect connections periodically and replace the breaker if mechanical or electrical life limits are reached.
