6.3–10 A motor protection switch for a swimming pool pump

The 6.3–10 A motor protection switch for swimming pool pumps is designed to protect electric motors installed in swimming pool systems.

Its function is to cut off the power supply when it detects an abnormal current that could cause damage to the motor, the wiring or the components in the electrical panel.

Adjustable range from 6.3 to 10 A

The device allows the protection level to be adjusted within a range of 6.3 and 10 A.

The adjustment must be carried out with reference to the rated current indicated on the motor’s nameplate. It must not be selected or adjusted solely on the basis of the power rating expressed in CV.

Application in swimming pool electrical panels

It can be used as a replacement part in frames designed for monitoring:

• Filter pumps.
• Hydromassage pumps.
• Compatible counter-current pumps.
• Auxiliary equipment with an electric motor.
• Other motors whose rated current falls within the permitted range.

Compatibility must also be checked in terms of voltage, the number of phases, the wiring diagram and the specifications of the motor protector originally fitted.

Pumps up to 2 CV

Trypool states that this model is suitable for pumps up to 2 CV. This specification should be understood as a marketing reference.

Two motors with the same power rating may have different rated currents depending on:

• Manufacturer.
• Performance.
• Voltage.
• Single-phase or three-phase power supply.
• Power factor.
• Operating conditions.

Therefore, the plate current is the criterion that must take precedence.

Professional installation

The motor protection switch must be installed inside a suitable electrical panel with the power supply disconnected.

The professional must check:

1. Rated motor current.
2. Voltage and number of phases.
3. Cable cross-section.
4. Coordination with the contractor.
5. Residual current protection.
6. Line protection.
7. Starting current.
8. Thermal adjustment.
9. Compatibility with the available space.

This work must be carried out by a qualified installer.
