1.7 Ex-proof Coils
1.7.1 Introduction
In our program we know two sorts of coils:
(1) Style: XB = II 1 G Ex ia IIC T6
II 1 D Ex ta IIIC T80°C
Intrinsic safe coil with LCIE approval.
This coil must be safeguarded with a isolating repeater.
(2) Style: XC = II 2 G Ex eb IIC T4
II 2 D Ex tb IIIC T130°C
Increased safety coil with LCIE approval.
