Product Features of the 1500V DC Isolator

Engineered specifically for DIN-rail switchgear, this 1500V DC Isolator guarantees strict electrical isolation for HVDC transmission systems.

Configuration Versatility: Available as a 2 pole dc isolator switch (A2) or a 4 pole dc isolator switch (A4, 4S, 4B, 4T), accommodating both single and dual string solar arrays.
High Withstand Capacity: Delivers an 8000V rated impulse withstand voltage (Uimp) and a 5000A conditional short-circuit current (Icc) to resist massive grid spikes.
Simultaneous Disconnection: Allows the simultaneous interruption of positive and negative polarity lines, ensuring complete isolation between arrays and inverters.
Mechanical Durability: Achieves an extended mechanical life of 10,000 cycles, securing long-term operational stability in commercial installations.
Built-in Safety: Operates with a dedicated knob positioning mechanism (OFF at 9 hr, ON at 12 hr) and maintains IP20 protection for internal panel mounting.

Field Applications for DC Switchgear

Deploying the EKD16-DB32 minimizes operational hazards across solar generation networks relying on a dependable 1500V DC Isolator.

Applications & Use Cases

Photovoltaic Inverters: Provides crucial localized disconnection at the DC input side of central and string inverters.
HVDC Distribution Systems: Functions as a primary safety barrier for commercial high-voltage direct current transmission lines.
