FEMA SDBAM | Steam and Hot-Water Pressure Limiters | Internal interlock, -20 to 70 °C, SIL 2
FEMA SDBAM pressure limiters provide maximum-pressure limiting with an internal interlock for steam and hot-water systems to TRBS, DIN EN 12828, DIN EN 12952-11 and DIN EN 12953-9. The special-construction switch uses a self-monitoring sensor built to PED 2014/68/EU and has a TÜV-verified bursting pressure of at least 100 bar. Ambient rating is -20 to 70 °C.
Key features
- Internal interlock after maximum-pressure cut-out
- Calibrated so switching occurs at the set point under rising pressure
- SPDT microswitch, 5 A inductive / 8 A resistive
- G1/4 internal / G1/2 external connection
- TÜV approval and SIL 2 to IEC 61508-2
