JDA Series Solid State Overload Relay

JDA-40

1. Application
The JDA series solid state overload relay is suitable for overload and phase-failure protection of A.C. motors with frequency 50/60Hz, voltage up to 660V, current from 0.7A to 600A. The features are reliable, lower energy depletion and broad adjusting current. The product conforms to IEC60947-4-1 stardand.

2. Motion Characteristic
1) Three-phase balance motion time as shown table 1
Table 1

No	Times of the setting current	Motion time			Ambient temperature
1	1.05	>2h			-40°C+55°C
2	1.2	<2h
3	1.5	<4min
4	7.2	10A	2s<Tp ≤ 10s	≤ 63A
		10	4s<Tp ≤ 10s	>63A

2) Phase-losing motion time as shown table 2
Table 2

No	Times of the setting current		Motion time	Ambient temperature
	Any two phase	Another phase
1	1.0	0.9	>2h	20?°C
2	1.15	0	<2h
