Scope of Application

JZ7 Intermediate Relay (hereinafter referred to as the relay) is suitable for AC 50Hz or 60Hz, voltage up to 380V, and direct voltage up to 220V control circuit, is used to control a variety of electromagnetic coils so that the signal amplification or signal is simultaneously passed to the control element.
The Intermediate Relay comply GB14048.5 and IEC60947-5-1.

Model and Meaning

Normal working conditions and installation conditions

Ambient temperature: -5℃+40℃, the average value does not exceed +35°C in 24 hours.
Altitude: no more than 2000m.
Atmospheric conditions: The relative humidity does not exceed 50% at +40°C, and higher relative humidity may be allowed at lower temperatures. For example, 90% at 20°C, special measures should be taken for the occasional condensation due to temperature changes.
Pollution level: 3 levels.
Installation category: Class III.
Installation conditions: The inclination of the installation face and the vertical is not more than ±5°.
Shock vibration: The relay should be installed and used in places where there is no significant shaking, shock and vibration.
