Overload relay DA2 1250-1600AF AC380-450V 004671136

Overload and short-circuit protection in electrical installations

The DA2 current rise release is a protective element designed to work with ETI Breaker EB2 series circuit breakers with a rated current of 1250-1600A. Its function is to detect current increases and disconnect the circuit in case of overload or short circuit, thus protecting devices and the electrical installation from damage. This ensures not only safety but also minimizes the risk of downtime.

Characteristics and application

The DA2 release is based on a control voltage of AC in the range of 380-450V, making it compatible with most standard power grids. It is designed for mounting in circuit breakers, where it acts as an additional protection function. Screw connection ensures a secure and durable electrical connection. This release finds application in electrical switchboards, control cabinets and all kinds of industrial and commercial installations requiring reliable protection against the effects of overloads and short circuits. This is particularly important in applications with motors with high starting current - the characteristics of the release allow it to react with a delay to short-term current surges, avoiding unnecessary circuit disconnection.

Installation and compatibility

The DA2 release is designed to work with ETI Breaker EB2 series circuit breakers with a current range of 1250-1600A. Installation is done by simple screw connection, which facilitates installation and servicing. Compatibility with cam connectors further increases the flexibility of using this element. It is important to select the correct release for a specific circuit breaker and the operating conditions of the installation.
