METTA twin sewage pump starting panels - Main materials CHINT

METTA electrical panels for sewage pumps are designed for the proper operation and protection of the twin pump assembly, while providing the possibility of full autonomy in control through start-stop float switches.

START-UP PANEL FOR TWIN 230V SEWAGE PUMPS WITH DOL START-UP CD2D1___

Plastic watertight enclosure, protection class IP54
General bipolar load switch
Automatic fuse depending on the current drawn by the pump to protect against overcurrent, short circuit
Power starter, one for each pump, for direct starting of the pump
Thermal relay to protect the pump from overload
Capacitors can be connected if required (not included)
I-0-II selector switch for manual or automatic operation, either by means of a self-locking starting float switch and a separate float switch for stopping, or by means of a start-stop float switch
Manual operation with start-up independent of the level
Automatic operation by alternating the starting sequence of the pumps at each new operating cycle, and both operating in parallel at rising levels
Indicator lights for operation, failure of each pump
Visual and audible overflow alarm with possibility of deactivation
Connection terminal block accompanied by a wiring diagram

Asymmetry, sequence and out-of-phase monitor
Thermomagnetic switch, one for each pump sized according to its current consumption for protection against overload, overcurrent, short-circuit, with frontal auxiliary contact
power starter, one for each pump, for direct starting of the pump
Connection terminals for internal heat pumps in series with the control circuit
I-0-II selector switch for manual or automatic operation, either by means of a self-locking starting float switch and a separate float switch for stopping, or by means of a start-stop float switch
manual operation with start-up independent of the level
Automatic operation by alternating the starting sequence of the pumps at each new operating cycle, and both operating in parallel at rising levels
Indicator lights for operation, failure of each pump
Visual and audible overflow alarm with possibility of deactivation
Connection terminal block accompanied by a wiring diagram

WASTEWATER PUMP START-UP PANEL 400V WITH WATER/SEWAGE PUMP START-UP CD2Y3___

Metal watertight enclosure, protection class IP54
General load switch
Asymmetry, sequence and out-of-phase monitor
Automatic “D” curve fuses in combination with thermal relay, suitable for motor protection against overcurrent, short circuit and overload or alternatively, thermomagnetic circuit breaker
a VSD starter, one for each pump, sized according to the pump capacity
Internal thermal pump connection terminals in series with the control circuit
I-0-II selector switch for manual or automatic operation, either by means of a self-locking starting float switch and a separate float switch for stopping, or by means of a start-stop float switch
manual operation with start-up independent of the level
Automatic operation by alternating the starting sequence of the pumps at each new operating cycle, and both operating in parallel at rising levels
Voltage, operation and fault indicators for each pump
Visual and audible overflow alarm with possibility of deactivation
Connection terminal block accompanied by a wiring diagram

CODE	ADDITIONS
F	Free voltage contacts for operation, fault and “AUTO” status indication for each pump, as well as for overflow indication (for panels AD2D1___)
F	Free voltage contacts for operation, fault and “AUTO” status indication for each pump, as well as for voltage and overflow fault indication (for AD2D3___ and AD2Y3___ panels)
M	3-display instrument with voltage transformers
Η	Permanent visual notification of a parallel operation error. In the event of an undetectable failure of a pump, and to avoid the phenomenon of only one pump operating without fault indication, a visual warning of simultaneous malfunction is activated for both pumps
P	Protection against dry operation via drilling power factor (cosφ) without Autoreset
A	12VDC power supply with battery connection for self-activation of the overflow alarm
C	Battery for overflow alarm autonomy 12VDC/3.2Ah
Χ	Reinforced universal socket
Ε	LED interior lighting

Control and automation panels for starting a wide range of rainwater/wastewater pumps.
Start-up of a twin pump assembly.
Protection against dry running of pumps by means of a float switch in the event of drainage of the pumping tank.
Start-up of the pumps by means of point level or adjustable differential level float switches with counterweight.
Visual and audible alarm of overflow of the pumping tank
