Rated operation voltage Ue: AC 240V 50Hz (or 60Hz). Rated insulation voltage Ui: 500V. Overvoltage setting value Uvo: 280V.
Release action characteristics: when the main circuit voltage is in the range of (85% ~ 110%) Ue, the release shall be able to keep the circuit breaker to work reliably for long term.
When the main circuit voltage is increased to 280 (1 ± 5%) V, the release assembled with NXB-125series circuit breaker should act and trip open NXB-125 circuit breaker. Mechanical and electrical life: the mechanical and electrical life of release is ≥ 4000 operation cycles.
Miniature circuit breakers are widely adopted. They are used for branch circuit protection in many electrical systems. However, as solar photovoltaic technology continues to expand rapidly, one question arises: Can I use a general miniature circuit breaker for PV?
In today’s digital age, data centers have become critical infrastructure. They enable our increasingly online lives and economies. They store massive amounts of data and power cloud services and applications.
An RMU, or ring main unit, is a type of medium-voltage switchgear. It consists of one or more circuit-breaker units with associated disconnectors, earthing switches, and instrument transformers.
A well-chosen distribution box ensures the safety and efficiency of your household electrical system. This article guides you through selecting a distribution box.
