1.Application
JSK4-d range air time-delay contactor relay is used in 50Hz(or 60Hz),rated voltage up to 380V or DC voltage up to 220V automatic control circuit, for time-delay components, and making or breaking circuit in forecast time .
2.Type and character
structure feature
Relay is the modular structure; JSK4-d is arranged by JZC3-22d contactor way relay and SK4-d range air time-delay terminal. JSK4 is arranged by JZC3-22 contactor way relay and SK4 range air time-delay terminal, all accord air damping theory, use powder metallurgy unit as air filters, regulate knobs, and then continuously change time-delay value.

3.Working and installation condition
Ambient temperature: -25°C~+60°C;
Elevation≤3000m;
Relative humidity is not exceeding 85% at the maximum ambient
temperature +40°C. Should give consideration to the dews, which would
appear due to temperature change; Vibration condition: relay should be installed at the place without significantly shaken, shock and vibration.
Installation gradient: the tilt gradient with vertical face should ≤5°, can installed by screw or rail track;
Pollution grade: Grade 3;
Installation categories: class Ⅱ;
marine relay Ambient temperature: -25°C~+60°C;
Air condition: be able to bear the influence of moisture in the air,salt fog,oil fog,mould,humid air on the sea.
Tilt: all direction should low than 22.5°
Vibration: all direction should low than 22.5°
Shock: can bear frequency 2-13.2Hz and amplitude in ±1mm or frequency 13.2~80Hz and acceleration ±7m/s2
Power voltage and frequency changes: steady-state voltage is +6%~-10% of rated voltage, steady-state frequency change is ±5% or rated frequency.
The inclined angle between the mounting surface and vertical surface no more than 5° .
