Question about Omron Healthcare Omron H3y-4 5 Second Timing Relay Timer H3y4
I see your comment to ignore:
To protect timer, read following:
1) Max load on this timer is 5 amp at 240volts
2) If load exceeds 5 amps, then use timer to control contactor.
Here is crude drawing showing basic wiring for pin timer controlling heavy amp load.
3) If amp rating on incoming wires exceeds 5 amp, for example is circuit breaker feeding circuit is 20-30 amps etc, then protect wires to timer using busman in-line fuseholder with fast-acting 5 amp cartridge fuse.
