WMS-WP6 Boiler Low Level Water Alarm- Mechanical 42300

 This mechanical boiler water low level alarm with float for sealed heating systems according to DIN EN 12828 consists of a cast brass body with DN 20 welding socket and a float mechanism, an electrical switch, test and manual re-set buttons.

TÜV-tested as a water level switch for a maximum operating pressure of 10 bar and a maximum operating temperature of 120°C. 
Designed for heating systems according to DIN EN 12828. If the water level in the boiler drops below a minimum  level, a float activates a switch which interrupts the power supply to the burner. A locking mechanism prevents the burner from restarting automatically. 
The test button allows the float to be lowered to simulate a low water alarm condition

WMS-WP6, brass (without locking mechanism)
Low water level alarm switch similar to WMS-WP6, but without reset.
For use in systems where a remote control panel re-set facility is provided
