1. EHD High Voltage DC Disconnector
Product Benefits
Wiring: Switch is non-polarized, all types of wiring and connections are possible.
Easy access without tools, and auxiliary contacts can be integrated without tools.
The mechanical device can be centered to meet the installation requirements.
Reliable position indicator through visible contacts.
The opening and closing of the switch is fully independent from the
speed of operation, ensuring safe operation under all conditions.
High temperature withstand: no derating up to 55 C(131F),functional
from -40 to+122F(-40 to +50°C).
Easy to install
Safe reliable operation
Designed for harsh environments
Vibration testing (from 13.2 to 100 Hz at 0.7 g).
Choc testing (15 g during three cycles).
Humid temperature testing (2 cycles, 55C/131F with 95% humidity level).
Salt mist testing(3 cycles with humidity storage, 40C/104F, 93% humidity after each cycle).
