Single-pole double-throw switch iSSW-20-1 20A 1CO A9E18070

Modular switch for reliable circuit control

This linear switch from the Acti9 series by Schneider Electric is a robust solution for manually switching electrical circuits on and off. Designed for both professional installers and end-users, it offers ease of use and reliable operation. The iSSW-20-1 switch is ideal for applications in residential, commercial and light industrial buildings.

Design and functionality

The switch features 2-position operation (on/off) and a single switching contact (1CO), providing flexibility in circuit configuration. Its compact dimensions – 1 module wide (18 mm) – allow for efficient use of space in the distribution board. The IP40 degree of protection guarantees protection against touch and protects against the ingress of solid objects larger than 1 mm. A durability of 30,000 switching cycles indicates the long service life of the device, and compliance with IEC 60669-1 and IEC 60947-5-1 standards confirms its safety and reliability.

Mounting and connection

The switch is designed for mounting on a DIN rail. It allows connection of copper wires with a cross-section from 0.5 mm² to 2.5 mm² (rigid or with a ferrule). Offset terminals facilitate wire connection, reducing installation time. Forced separation according to DIN VDE 0113 provides additional safety.

Operating parameters

The switch operates at a rated voltage of AC 250V and a rated current of 20A. This makes it suitable for circuits with medium loads. A wide operating temperature range (-20°C to +50°C) allows it to be used in various environmental conditions.
