Why Choose the ABB OTDC500E11 DC Switch-Disconnector?
The ABB OTDC500E11 is a high-performance 500 A two-pole DC switch-disconnector designed for reliable isolation and switching in 1000 V DC power systems. As part of the ABB OTDC series, it is specifically engineered for demanding DC applications requiring dependable disconnection, compact installation and efficient current handling.
The OTDC500E11 uses a single-circuit configuration with one positive and one negative path, providing simultaneous isolation of both conductors in a DC circuit. Its front-operated mechanism is positioned between the poles, providing a practical arrangement for integration into photovoltaic equipment, DC distribution assemblies and industrial electrical enclosures.
With a rated operational current of 500 A at 1000 V DC under the DC-21B utilisation category, the OTDC500E11 combines high-current switching capability with a rated short-time withstand current of 10 kA for 1 s. The switch is base mounted, includes its terminal bolt kit and requires the operating handle and shaft to be ordered separately.
