Undervoltage release NA2 800-1600AF AC220-240V 004672300

Undervoltage release – reliable installation protection

This NA2 undervoltage release, designed to work with ETI circuit breakers, provides effective protection against voltage drops in the network. It is a key element protecting sensitive devices from damage caused by unstable power supply. The device is dedicated to circuit breakers with a rated current of 800-1600A, making it an ideal solution for both industrial and commercial installations.

Functionality and application

The NA2 release reacts to a voltage drop by disconnecting the circuit and protecting the connected devices. Its operation is based on monitoring the AC 220-240V control voltage. Since it has no delay (delayed: false), it provides a quick response in the event of power supply problems. Screw connection facilitates mounting and integration with existing electrical infrastructure. Compatibility with cam switches expands the scope of application of this component.

Key features and benefits

• Fast response: Lack of delay in operation guarantees immediate protection against the effects of voltage drops.
• Versatility: Designed for circuit breakers with a rated current of 800-1600A, which increases its usefulness in various applications.
• Easy installation: Screw connection ensures simple and quick installation in existing installations.
• Compatibility: Works with both circuit breakers and cam switches, offering flexibility in configuration selection.
• Reliability: A product of the ETI POLAM brand is a guarantee of high quality workmanship and durability.
• Protection against damage: Protects connected devices from failures caused by unstable supply voltage.

Technical data
