Module switch for reliable power switching

This four-pole SPMP/4P40 module switch, manufactured by Spamel, is a key element of electrical installations requiring reliable switching between different power sources. Designed to operate in network-generator (I-0-II / 1-0-2) systems, it ensures safety and continuity of power supply in emergency situations. This switch is ideal for both professional installers and end-users looking for a solid and proven solution.

Features and application

The SPMP/4P40 switch allows easy and safe switching of power between two circuits, which is particularly important in emergency power systems where maintaining continuous operation is a priority. The modular design simplifies mounting on a standard TS35 rail, and the compact dimensions (4 modules wide) allow for optimal use of space in the distribution board. The switch finds application in residential, commercial and industrial buildings where high reliability and power supply safety are required.

Solid construction and parameters:

The switch is characterized by a rated current of 40A, allowing for safe loading up to 40 amps. Its versatility results from the rated voltage of 240/415V, enabling operation in different electrical networks. The four-pole design allows switching of all phases and neutral (depending on the configuration). The IP20 degree of protection provides protection against touching fingers and against the ingress of solid objects larger than 12.5 mm – standard protection for devices mounted inside distribution board enclosures. Mounting on a TS35 rail is simple and quick, does not require the use of additional tools. Mechanical endurance at 8500 cycles guarantees long-term and trouble-free operation of the device. An important aspect is also the recommended tightening torque of the terminals of 1.2 Nm – this ensures a secure connection of the wires without the risk of damage to the terminals; exceeding 2 Nm may cause them to break, which is an additional safety feature.

Thanks to this, the switch not only ensures reliable operation, but also facilitates the installation and maintenance of the electrical system. It is important to remember to tighten the screws in the terminal block correctly – a too loose connection can lead to overheating, and a too tight connection – to damage the terminal.
