The CATU MV-137 Class 2 Insulating Boots provide reliable electrical protection for applications up to 17 kV, tested at 20 kV. These boots resist over 35 kV at the sole for 3 minutes and 20 kV over the entire boot for up to 8 hours. Designed for safe operation on live circuits, they also protect against step voltage while offering comfort and ergonomic use.
