Miniature switch Promet MP0-3 telescopic 1P 1Z 10A 400V IP40

Promet MP0-3 telescopic miniature switch is a compact single-pole, single-throw control component rated for 10 A at 400 V with IP40 protection. Designed for installation in confined electrical assemblies, this switch provides a straightforward on/off function in indoor environments. Its telescopic actuator allows for operation where mounting depth is limited while maintaining clear mechanical action for control panels and small machinery.

Advantages

The telescopic design reduces required mounting depth without compromising contact reliability. With a 10 A, 400 V rating the switch supports typical control and signalling circuits in industrial and commercial equipment. IP40 protection offers basic ingress resistance appropriate for indoor use, while the single-pole single-throw configuration simplifies wiring and integration into existing control schemes.

Suitable for

• Control panels and switchboards in indoor installations
• Small machinery and automation devices requiring simple on/off control
• Appliances and equipment with limited mounting depth
• Maintenance and retrofit projects where compact switching elements are needed

Key specifications

• Switch type: miniature telescopic single-pole, single-throw
• Rated current: 10 A
• Rated voltage: 400 V
• Protection class: IP40 (indoor use)
• Actuator: telescopic (low profile for constrained mounting depth)
• Contact configuration: 1P 1Z (single-pole, single-throw)

How to use

Install the switch into the control panel or equipment according to the manufacturer’s mounting instructions, ensuring the panel cut-out and mounting depth accommodate the telescopic actuator. Connect supply and load conductors to the designated terminals, observing polarity and live conductor safety practices. Verify that the connected circuit does not exceed the 10 A, 400 V ratings and that the installation environment is consistent with IP40 protection. After wiring, operate the actuator to confirm reliable mechanical movement and correct electrical switching before placing the equipment into regular service.

Usage recommendations

Use the switch only in dry, indoor locations consistent with IP40 protection. For circuits approaching the rated current or voltage, consider verifying thermal limits and use appropriate overcurrent protection. Avoid exposure to dust accumulation or direct water spray; regularly inspect contacts and mounting integrity during preventive maintenance.
