Disconnect switch DL 4P 100A FR/100A/4P NEO 87.125

Isolator switch – reliable circuit disconnection

The DL 4P 100A FR NEO isolator switch is an element used for safe and reliable disconnection of electrical circuits. Designed for both home and industrial installations, it provides effective isolation and protection during maintenance or repairs. Its construction allows for visual verification of the circuit status – open/closed, which increases work safety.

Construction and application

This isolator switch, with a rated current of 100A, is four-pole (4P), which means it disconnects all phase and neutral wires simultaneously. This allows for complete isolation of the load from the power supply. Mounting is done on a standard TH35 (DIN) rail, which facilitates integration with existing NEO modular apparatus. This is particularly important during installation modernization or the construction of new facilities.

• Safety: Provides complete circuit isolation on the supply and receiver side.
• Convenience: Allows for easy and quick disconnection of the load for maintenance or repair work.
• Versatility: Suitable for use in various types of electrical installations – both single-phase and three-phase.
• Mounting: Standard mounting on a TH35 rail facilitates integration with other NEO apparatus elements.

Characteristics and benefits

The construction of the DL 4P 100A FR NEO isolator switch has been designed with durability and reliability in mind. The materials used ensure resistance to environmental conditions and long device life. It is worth emphasizing that this isolator switch is not a circuit breaker – its task is only to disconnect the circuit, and not to protect against overloads or short circuits (circuit breakers MCB are used for this purpose). Thanks to this, it can be used in places where a certain and reliable isolation of the load is required without the need to interfere with the protection system.
