Panel fit and contact ratings
The 3RH2353-1CG60-0KA0: Its 5 normally open instantaneous contacts handle the logic-level loads that signal PLC inputs, relay coils, and contactor holding circuits.
Switching performance and environment
The maximum switching frequency for DC loads is 10,000 operations per hour — above that the contact erosion rate accelerates. For AC loads at 50 Hz the operating range factor is 0.8–1.1, and at 60 Hz it is 0.85–1.1, meaning the contactor picks up reliably between 80% and 110% of rated control supply voltage. Minimum relative humidity is 10%.
