Sulzer ABS CA 462 Temperature and Leakage Relay
The Sulzer ABS CA 462 is designed to detect leakage and temperature in pumps and mixers. The amplifier is housed in a standard enclosure for DIN-rail mounting and is available in two versions: 110–230 VAC or 24 VDC supply.
To minimise the risk of false alarms, a leakage fault must be present for about 10 seconds before it is signalled. The unit has separate alarm outputs for temperature and leakage, plus a main contactor relay output that is energised depending on the alarms, with a manual reset option. Plug-in connectors make installation simple, and a Xylem MiniCas adaptor is included in the kit.
Main features
- Leakage monitoring with approx. 10 s alarm delay against false alarms
- Wide resistance range for leakage detection, 0–100 kΩ
- Temperature monitoring with PTC or Klixon sensors
- Separate alarm relays for temperature and leakage
- Pump blocking (main contactor) relay with manual reset option
- Plug-in connectors; DIN-rail mounting (35 mm)
- Xylem MiniCas adaptor included
Applications
- Protection of submersible wastewater pumps
- Protection of submersible mixers
- Pumping station control panels
