NLDS1 series products have a large flow capacity and are suitable for C-level (II-level) and D-level (III-level) protection in low-voltage distribution systems.

Different combination wiring methods are chosen based on different power supply systems.

High energy varistor, nanosecond response speed;

Equipped with overheating and overcurrent protection;

Local indication1) and remote alarm contact2);

1) It visually displays the working status of the protector on the protector

2) It provides contacts for remote monitoring of protector status, which requires external wiring.

Pluggable in charged condition, module replaceable in case of failure.

Note 1): The maximum continuous operating voltage is optional, with 275V, 385V, 420V, etc.

Note: Numbers 1-44 can be derived from varieties with alarms (add B at the end of the model), while 6-17 and 24-44 can be derived from varieties with remote communication contacts (add X at the end of the model).
