Spamel SPMP/1P40 Modular Power Selector Switch 1P 40A

The Spamel SPMP/1P40 is a professional-grade modular power selector switch engineered for single-phase electrical systems. With a rated current capacity of 40A, this device provides a robust solution for managing power distribution by allowing seamless switching between two distinct power sources. Its design is optimized for integration into modern electrical switchboards, offering a reliable mechanism to maintain continuous power supply in both residential and industrial environments.

Advantages

The primary benefit of this modular switch is its space-saving design, which allows for quick and efficient mounting on standard DIN rails. By utilizing high-quality materials, the switch ensures long-term durability and consistent performance under standard operating conditions. Its straightforward operation minimizes the risk of errors during source switching, contributing to a safer electrical installation. Furthermore, the modular construction facilitates easy maintenance and integration with other DIN-rail mounted components within a distribution board.

Suitable for

• Residential power source switching between grid and generator
• Industrial control panels requiring manual source selection
• Single-phase electrical distribution systems
• Emergency power supply management

When it may not be suitable

This device is strictly designed for single-phase electrical systems and cannot be used in three-phase installations. It is not intended for high-voltage industrial applications exceeding its rated current capacity or for environments with extreme moisture or corrosive gases that could compromise the internal contacts.

Key specifications

• Rated current: 40A
• Number of poles: 1P
• Mounting type: DIN rail
• System compatibility: Single-phase

How to use

The switch should be installed by a qualified electrician within a standard distribution board on a 35mm DIN rail. Ensure that the power supply is disconnected before beginning the installation. Connect the incoming power lines to the designated input terminals and the load line to the output terminal. Once securely mounted and wired, the switch can be operated manually using the front-facing toggle to select the desired power source.

What to consider before purchase

• Verify that your electrical system is single-phase
• Ensure the 40A rating is sufficient for your total load requirements
• Check available space on your DIN rail
• Confirm that the installation environment meets standard indoor requirements

Usage recommendations

Regularly inspect the switch for any signs of wear or loose connections during routine maintenance of your electrical panel. Ensure that the switch is operated only within its specified current limits to prevent overheating and ensure a long service life.
