Fuse Recommendation
1. To avoid distortion, use parallel wires for control power and voltage inputs. Keep
the fuse close to the power source.
2. Use with 480Y/277V and 208Y/120V systems.
3. For an open delta PT connection with 120V L-L secondaries, use system type 31.
NOTES:
Place over-current protection as close to the device as possible.
For selecting fuses and circuit breakers other than those listed above, use the following criteria:
• Rate over-current protection as listed above.
• Select current interrupt capacity based on the installation category and fault current capability.
• Select over-current protection with a time delay.
• Base the voltage rating on the input voltage applied.
• If a 0.25A fuse is not available with the required fault current capability, use a fuse rated at a maximum of 0.5A.
Direct Connect Control Power C (Phase to Phase)
• Phase to Phase only when voltage <415 +10%VAC max.
• See Table below.
• Control Power Transformer 120 or 240VAC. Secondary 50VA max.
• See Table below.
Control Power
• DC Control Power 100 VDC
• See Table below.
