Brownout trigger with auxiliary power and iMNx-230 220240 VAC A9A26969

iMNx-230 undervoltage release from the Acti 9 series

The iMNx-230 undervoltage release belongs to the Acti 9 family and is designed to work with iC60 miniature circuit breakers, iID residual current circuit breakers, iDPN Vigi residual current breakers with overvoltage protection, and iSW-NA isolators. The device operates independently of the supply voltage.

A drop in the supply voltage does not cause the automatic tripping of the release. A red mechanical indicator on the front face of the product signals the "tripped" status of the associated device.

Design and compatibility

The compact housing with a width of 18 mm (1 module) allows for mounting on a standard DIN rail using a "clip-on" system. The release is compatible with a wide range of Schneider Electric devices: iC60 miniature circuit breakers, iID residual current circuit breakers, iDPN Vigi residual current breakers with overvoltage protection, iSW-NA isolators, and the two-terminal versions of these devices.

The connection system based on spring terminals supports wire cross-sections from 2.1 mm² to 11 mm², both single-core and multi-core (with ferrules). A tightening torque of 1 N·m guarantees a secure electrical connection while maintaining ease of installation.

Operating parameters and safety

A rated control voltage of 220÷240 V AC at a frequency of 50/60 Hz ensures universal application in European power grids. The device maintains full functionality in extreme temperature conditions—the operating temperature ranges from -35°C to +70°C, and the storage temperature from -40°C to +85°C.

The device weight is only 87.83 g, which minimizes the load on the mounting rail while maintaining a robust mechanical construction. A relative humidity of up to 95% at 55°C confirms resistance to harsh environmental conditions typical for electrical switchboards.

Compliance and standards

The release meets the requirements of the international standard IEC/EN 60947-5-1, which defines the safety of low-voltage control devices. The product features class 2 tropicalization, confirming its suitability for operation in high humidity and temperature environments characteristic of tropical climates.
