CHINT V9 Under Voltage Release for NB1, NBH8, NB1L,NBH8LE

Brand Name: CHNT

Type: Mini

Origin: Mainland China

Is Smart Device: no

Certification: NONE

Model Number: for NB1

1. Major function

To be assembled with circuit breaker to achieve over/under voltage protection

2. Parameters and performance

Rated operation voltage Ue: AC 240V, 50Hz;

Overvoltage operation setting value Uvo: 280V;

Rated insulation voltage Ui: 500V; Tripping characteristics: the release is assembled with NB1-63 series circuit breaker. When the applied voltage is reduced to 35%Ue or increased to 95% ~ 105% of the over-voltage setting value, the release should drive the circuit breaker to act. When the applied voltage is below 35%Ue or above 105% of the over-voltage setting value, the release should be able to prevent the circuit breaker from closing. When the supply voltage is above 85% Ue and below 95% of over-voltage setting value, the circuit breaker should be able to close normally. The upper limit of the applied voltage should be less than 110% over-voltage operation setting value. Mechanical and electrical life: the mechanical and electrical life after the release is assembled with the circuit breaker should be ≥ 4000 cycles, of which, 500 cycles for over-voltage trip

3. Assembly and installation of the product
