ETA 1-Pole Panel Mount Isolator Switch 100A, IP00, IP40, 480V AC, Quick Connect 8345-B01A-U3M0-DB1B1B-100A

ETA 8345-B01A-U3M0-DB1B1B-100A is a robust 1-pole panel mount isolator switch engineered for demanding electrical isolation requirements in industrial environments. Designed for installation in control panels and automation equipment, it features a magnetic hydraulic trip-free mechanism with toggle actuation, providing reliable performance and safety.

This isolator switch is rated for a switching current of 100A and accepts up to 480V AC or 80V DC, making it suitable for heavy-duty applications such as control equipment, communications systems, transportation (including rail systems), and power supply distribution. The quick connect terminal design speeds up installation and wiring, while the panel mount form factor and compact size (63.5mm length, 19.1mm width, 67.7mm depth) ensure it fits easily in crowded panels.

With ingress protection ratings of IP00 and IP40, this device offers flexible mounting in controlled environments. It can operate from -40°C to 85°C, making it reliable under extreme temperature conditions. The ergonomic black handle ensures positive switching and indicator visibility during operation. Auxiliary contacts are not available for this variant, simplifying its function as a dedicated isolator.

The ETA 8345 series is designed with industry-standard dimensions and insulation resistance exceeding 100MΩ, supporting applications where electrical safety and isolation are critical. It meets international certifications including CCC, IEC, RoHS, UL, and VDE, suitable for global industrial use. User notes clarify that these CBE isolator switches are tailored for system and equipment protection, not large MCBs intended for distribution wiring fault protection.

Its medium delay trip characteristics enable versatility across a variety of industrial and automation control systems. Typical installation scenarios include machinery safety isolation, industrial power distribution panels, control system enclosure integration, and automation platforms requiring rapid electrical isolation.

ETA's reputation for quality is reflected in this product's certifications, build quality, and robust technical specifications. Engineers and technical buyers can depend on the 8345-B01A-U3M0-DB1B1B-100A for demanding projects where dependable electrical isolation is essential.
