JR56-20
1. Application
   JR56 series thermal relay is used in the circuit of 50/60Hz, rated insulation voltage 660V, rated current 0.3-95A for protecting the phase break when the electric motor is overloaded. The relay has different mechanism and temperature compensation. It can be plugged in CJX3 series AC contactor. The product conforms to IEC60947-4-1.

2. Motion Characteristic: Three-phase Balance Motion Time
No Times of the setting current Motion time Start condition Ambient temperature
1 1.05 >2h Cold state 20?°C
2 1.2 <2h Heat state
(Following the No.1 test)
3 1.5 <4min
4 7.2 10A 2s<Tp ≤ 10s ≤ 63A Cold state
10 4s<Tp ≤ 10s >63

3. Phase-losing Motion Characteristic
No Times of the setting current Motion time Start condition Ambient temperature
Any two phases Another phase
1 1.0 0.9 >2h Cold state 20?°C
2 1.15 0 <2h Heat state (Following the No.1 test)
