Undervoltage release (IZMX-UVR230AD-1) 184162

Undervoltage release – reliable protection of installations

The IZMX-UVR230AD-1 undervoltage release is a key element ensuring safety and continuity of operation in electrical circuits. The device is designed to work with Eaton IZMX and INX series circuit breakers, as well as overload relays and motor starters. Its task is to disconnect the power supply when the voltage drops below the set threshold, protecting connected devices from damage caused by too low voltage.

Functionality and application

This undervoltage release is designed for mounting in ACB air circuit breakers, providing an additional layer of protection. Thanks to a wide range of control voltages (208…240 V AC 50/60 Hz and 220…250 V DC) it is compatible with various power systems. The possibility of connection via a flat plug-in connection simplifies installation and replacement. The device finds application in:

• Circuit breakers (IZMX and INX series)
• Overload relays
• Motor starters
• Motor safety disconnectors
• Load disconnect switches

Characteristics and benefits

The Eaton IZMX-UVR230AD-1 undervoltage release is not only a protective element, but also an investment in system reliability. Its design ensures a quick response to voltage drop, minimizing the risk of damage to sensitive equipment. Additional advantages include:

• Universal voltage: Possibility of powering with both alternating current (AC) and direct current (DC).
• Compatibility: Designed to work with popular Eaton IZMX and INX series circuit breakers.
• Easy installation: Flat plug-in connection simplifies installation and servicing.
• Wide voltage range: Support for 208-240V AC and 220-250V DC voltages provides application flexibility.
• Low power consumption: Power consumption at 5 VA/W AC/DC minimizes the impact on system energy efficiency.
• High resistance to external conditions: Operation at temperatures from -25°C to 70°C guarantees reliability even in harsh industrial conditions.

The energy consumption during attraction is a maximum of 910 VA/W with a switching time of 35 ms, which ensures a quick response to voltage changes. The device has no normally open, normally closed or changeover contacts, which simplifies its integration with existing control systems. The maximum number of operations per minute is 3, which provides an appropriate operating frequency in typical industrial applications.
