Why Choose the Chint NH4-80108 100 A Single-Pole Isolator?
The Chint NH4-80108 is a 100 A single-pole switch disconnector designed for manual switching and isolation of one electrical circuit conductor. Part of the Chint NH4 series, it provides an isolating function in the open position within an appropriately designed electrical installation.
Its modular DIN rail construction supports installation inside suitable distribution and control enclosures. The NH4 range is designed to match Chint NB series MCBs and RCBOs, helping panel builders arrange switching and protective devices within a coordinated assembly.
With an 18 mm module width, the NH4-80108 provides a compact manual switching point. Its single-pole configuration disconnects one conductor, so the complete isolation arrangement must reflect the circuit design and the conductors that need to be disconnected.
Key Advantages
- 100 A rated current for appropriately designed circuits.
- Single-pole operation provides a dedicated switching point for one conductor.
- Provides an isolating function in the open position.
- 18 mm modular width helps conserve enclosure space.
- DIN rail mounting suits modular electrical assemblies.
- Designed to complement Chint NB series protective devices.
Key Features
- Chint NH4 switch disconnector series.
- 100 A rated current.
- Single-pole configuration.
- Manual ON/OFF operation.
- AC-22A utilisation category.
- IP20 device protection rating.
- Cable and compatible busbar connection options.
- Specified to IEC/EN 60947-3.
Manual Switching and Isolation for Electrical Assemblies
A switch disconnector combines manual switching with an isolating function. Opening the NH4-80108 disconnects the conductor passing through its single pole; other conductors and independent supplies remain unaffected.
The device does not provide automatic overload or short-circuit protection. Suitable protective devices must therefore form part of the installation, with the switching arrangement selected for the connected load and the required isolation function.
Typical Applications
- Manual switching within suitable distribution assemblies.
- Single-pole isolation points where permitted by the circuit design.
- Modular electrical control panels.
- Equipment supply circuits with separate overcurrent protection.
- Replacement of matching isolators during panel maintenance.
- OEM electrical assemblies requiring manual disconnection.
