Lodestar CL25
Description
Lodestar CL25 models is a simple solution for fault detection. Optimal factory settings allow CL25 to be used without any configurations in most cases. Just activate the device and place it on a conductor - CL25 will do its job in the best possible way.
CL25 fault indicators operate independently of each other. It means that current and voltage values can be read from each phase separately.
Lodestar CL25 benefits:
• Brightest Light 360° Visibility - 3 ultra bright wide-angle LEDs provide overlapping fields of light;
• Simple installation - using a single hot stick;
• Easy to replace - no additional settings are required;
• Dynamically changing sensitivity based on a load current;
• Minimum fault sensing 25A;
• Auto-Detect Network Frequency — intellectual algorithms allow it to work in networks with frequency of 50 or 60Hz without reconfiguration ;
• Enhanced resistance to interference conditions in the air.
