Transfer switch network-aggregate I-O-II 25A 4-pole SSQ 425 002421444

Modular switch for reliable power source switching

This four-pole modular switch SSQ 425 with a rated current of 25A is a reliable solution for switching between power sources, especially in emergency situations such as power outages. Its design allows for mounting on TH35 rails in standard modular distribution boards. The switch is widely used in both home and industrial installations where high power availability is required.

Functionality and safety

The SSQ 425 switch offers three operating positions: I (mains), 0 (off), and II (generator), allowing for easy and safe switching between different energy sources. The ability to secure the selected position with a seal (I or II) prevents accidental changes to the settings and ensures continuous power supply. The distance between contacts in the off position exceeds 3 mm, guaranteeing complete circuit isolation. The switch is designed in accordance with PN-IEC 60947-3 standard and has a certificate from Biuro Badawcze DS. Jakości (BBJ), confirming its high quality and compliance with applicable standards.

Installation and compatibility

The switch is easy and intuitive to install thanks to the standard mounting method on the TH-35 rail. It accepts stranded wires with a cross-section of 1.5 - 10 mm² and solid wires with a cross-section of 1.5 - 16 mm², providing flexibility in wire selection. The IP20 degree of protection protects against touching live parts and the ingress of solid objects larger than 12.5 mm. The ability to mount in any position further facilitates installation in various distribution board configurations.
