Growth trigger Z-LHASA/230 248442

Surge trigger – protection and functionality in one

The surge trigger Z-LHASA/230 is a component used to expand the functionality of overcurrent circuit breakers, providing additional protection for the electrical installation. This device, manufactured by Eaton, is designed for mounting in protective circuit breakers with a maximum current of 125A and reacts to sudden current surges that can occur during the starting of motors or other high-power devices. This prevents overloads and damage to the installation.

Characteristics and application

This surge trigger is dedicated to working with overcurrent circuit breakers (MCB), expanding their capabilities. Its main task is to detect and respond to momentary current spikes caused by certain devices – such as motors – with high inrush currents. This protects the circuit from unwanted tripping caused by these short-term overloads. Installation is simple and takes place after the main circuit breaker has been installed, making it an ideal solution for both professional installers and end-users looking for additional protection.

Key features and benefits

• Wide voltage range: The trigger works with installations with a voltage of AC 110-415V, ensuring its versatility.
• Compact dimensions: A width of 1.5 modules (27mm) allows for easy installation even in tight switchboards.
• Suitable for late installation: Possibility of connection after installation of the overcurrent circuit breaker facilitates the modernization of existing installations.
• Overload protection: Protects the circuit from damage caused by sudden current surges, especially during the starting of motor-driven devices.
• Compliance with standards: The device meets appropriate safety standards, guaranteeing reliable operation.
• Terminal cross-section: Allows connection of wires with a cross-section from 1 to 25 mm², providing flexibility in wire selection.
• Current consumption: Maximum current consumption at switch-on at voltage Un is 2A – a parameter important when selecting appropriate protection.

It is worth remembering that the surge trigger does not have fault signaling contacts or switching contacts, focusing solely on the function of protecting against current surges. This is a dedicated solution for those who want to increase the reliability of their electrical installations without the need for more complex monitoring systems.
