O Series
High-voltage Current-limiting Fuse Protector For Oil-immersed Transformer Protection
Introduction
O Series is used for indoor electrical systems with a rated voltage of AC 3.6~12KV (50Hz). O Series can be used in conjunction with electrical protection products such as load switches and vacuum circuit breakers to protect high-voltage motors and other electrical equipment from overload and short circuit.

Features
Under specified conditions, it can reliably break any fault current between the minimum breaking current and the rated breaking current.
The fuse should be placed in the transformer oil, and its surrounding temperature should not exceed 100℃.
Good current limiting effect and high breaking capacity.
Low power consumption and low temperature rise.
The action characteristics are fast, and the ampere-second characteristic error is less than ±10%.
Equipped with a spring-type striker, the striker has the advantages of large contact surface and low pressure.
