Electric release with 30 sec time delay - 12/24V

Electric field sensor automatically detects water level and activates bilge pumps. The trigger activates when the water level reaches 51 mm and switches off when the level falls below 13 mm. Suitable for use with 12 and 24 V Whale bilge pumps.

Features a 30-second delay for optimum pumping. Prevents reactivation when installed in a small sump and allows pumping at levels below 13 mm. Easy installation: two cable colors and bottom or side mounting to suit your installation.
