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.
