Low-water cut-out switchgear kit for domestic water systems

Low-water cut-out switchgear kit for domestic water systems

low-water cut-out switchgear kit WMS G 1¼

4204510

The kit detects low water using pressure measurement and is adjusted to the increase in pressure and pressure maintenance of non-potable water. The kit is used exclusively for single-phase products.

For horizontal pumps, the connection is established for 1" or 1"1/4 using a reduction nipple M/M 1"1/4-1". For vertical pumps, the oval shape 1"1/4 connection is possible using an oval counter flange with an O-ring.

The switch-on and switch-off pressure for needs-based operation and pressure range of the pump is configured on the reverse pressure switch. The pressure measurement is carried out using a single-phase low pressure switch. If the pressure decreases and reaches 0.1 bar, the pump is stopped. The pump starts again when the pressure rises and reaches 0.5 bar. These starting and stopping pressure values are factory settings and can be changed. You can use the pressure gauge to define the values.

Scope of delivery

The kit is supplied with the following, unmounted components:

• Single-phase low-pressure switch
• T-connector 1/4’’ M/F/F
• Pressure gauge 0-6 bar
• M/M reduction nipple 3/8’’ – 1/4’’

PTC thermistor tripping unit

509275993

PTC thermistor triggering relay for switch cabinet installation (1 device per motor required). The thermistor overload relays monitor motors which are equipped with PTC thermistor temperature sensors. The temperature sensors are installed in the windings of the motors and measure the heating up of the motor directly. This enables direct monitoring and evaluation of various operating conditions. A collective fault signal (SSM) is possible with corresponding wiring in the switch cabinet.
