Product Overview
Panel-mount DC isolator with five voltage options from 600V to 1500V and 32A continuous current rating in 2-pole and 4-pole configurations. The 4-pole version simultaneously breaks both positive and negative conductors — required in floating-negative systems and where local code mandates bipolar disconnection.
This family is commonly used as a string-level or combiner input disconnect. The rated voltage and current must be matched to the maximum string Voc and Isc of the circuits it protects.
The EKD16-DB32 dual-pole isolator is sized for string-level disconnection between PV array and inverter or combiner box input. Confirm string Isc and open-circuit Voc against the rated breaking capacity before specifying — the 32A current rating covers standard 72-cell string configurations at both 1000V and 1500V system voltage.
Applications
PV string and array protection
Combiner box internal protection
Inverter DC input circuits
Utility and C&I solar BOS
Frequently Asked Questions
When do I need a 4-pole isolator instead of 2-pole?
A 4-pole isolator simultaneously breaks both the positive and negative conductors. This is required in floating-negative DC systems or where local code specifies full bipolar disconnection for safe isolation. 2-pole is used where one conductor is earth-referenced.
Can EKD16-DB32 be used as a string disconnect inside a combiner box?
Yes, this is a primary application. DIN rail mounting fits standard combiner box rails. Confirm the rated voltage matches or exceeds the string Voc and the rated current covers the string Isc before specifying.
