Product Details

The Chint NH4 Series 2 Pole 100A Isolator (model NH4-80208) is a reliable electrical isolator switch designed for professional and domestic applications. It provides a clear and secure method to manually disconnect electrical circuits for safe maintenance and servicing. Ideal for use in distribution boards, control panels, and wiring systems where dependable isolation is essential.

Manufactured by Chint, a trusted global brand in electrical components, this isolator is built for durability and long term performance. It is rated at 100 amps and suitable for typical UK supply voltages up to 415V. The two pole design ensures both the live and neutral conductors are disconnected at the same time, helping to reduce the risk of electrical back feed and improving overall site safety.

The compact construction makes this isolator easy to install in electrical panels and consumer units. It is designed for clear visual and physical isolation of circuits, making it ideal for service and maintenance work. Unlike a circuit breaker, this isolator focuses on manual disconnection rather than overload protection, making it a practical choice for dedicated isolation points.

This model is suitable for a wide range of applications including residential, commercial, and light industrial installations. Whether used in a domestic consumer unit or a commercial distribution board, the Chint NH4 isolator delivers consistent and dependable performance.

Installation should always be carried out by a qualified electrician in accordance with UK electrical regulations. With its simple, robust design and trusted brand quality, this isolator offers peace of mind where safe circuit isolation is required.
