Switch with indicator light iSW-L-20-1 20A 1NO A9S61120

Switch with indicator light – reliable installation protection

The iSW-L-20-1 switch is a single-pole circuit breaker with an indicator light, designed to protect electrical circuits with a rated current of 20A. It belongs to the Acti 9 range from Schneider Electric, characterized by high quality and reliability. This device finds application in both home and industrial installations, providing effective protection against overloads and short circuits.

Functionality and construction

The iSW-L-20-1 circuit breaker occupies one module width in the distribution board (18mm), allowing for optimal use of space. It has a normally open contact (1NO) and a built-in red indicator light that indicates the circuit is on. Made of high-quality materials, it ensures long-lasting and trouble-free operation. Forced opening of the contacts in accordance with DIN VDE 0113 standard further increases safety.

• Quick status identification: The indicator light facilitates visual control of the circuit status, which is particularly useful during maintenance and repairs.
• Compact dimensions: A width of 1 module allows for mounting in tight spaces.
• Safety: Forced separation of contacts provides additional protection against electric shock.
• Versatility: Suitable for use in various types of electrical installations – both building and industrial – thanks to compliance with EN/IEC 60 898 and EN/IEC 60 947-2 standards.
• High resistance: Protection class IP20 protects against touching with fingers and against the ingress of solid objects larger than 12.5 mm.

The device is designed to operate at a rated voltage of 250V AC and a minimum rated voltage of 230V. The maximum power of the light source is 1.2W, and the installation depth is 75.5 mm. Thanks to these parameters, the circuit breaker is perfect for protecting lighting, socket outlets and other electrical devices with a power not exceeding 4600W (at 230V). Installation is simple and intuitive, and thanks to the standard module dimensions, the circuit breaker can be easily integrated with existing electrical installations.
