(c) Relative humidity: not exceeding 95% at+20 ℃;

(d) Protection level: IP55(Customizable according to user requirements). Scope of application: Altitude 0~4000m.；

(e) Power frequency withstand voltage: normally open contact 2000V, 1min, normally closed contact or single pole double throw contact: phase to phase 1000V, 1min, ground 2000V, 1min;

(f) Insulation performance: normally open contact 2500V, 1000M Ω, normally closed contact or single pole double throw contact: phase to phase 1000V, 500M Ω, ground 2500V, 1000M Ω.
