Switching frequency and thermal clearances
The 3RT2026-1AP00-ZW96: Maximum switching rate depends on duty: 1,000 cycles/hour in AC-1 (resistive), 750 cycles/hour in AC-2 or AC-3 (motor start/run), and 250 cycles/hour in AC-4 (plugging/inching). Storage temperature spans -55 to +80 °C, so the part tolerates unheated warehouses but not prolonged exposure above that ceiling.
Auxiliary contacts and mechanical endurance
An auxiliary switch is fitted as standard — the contactor carries a built-in auxiliary contact block, saving a separate add-on for feedback or status signals. Mechanical endurance is rated 10 million operating cycles typical, which for a contactor in a conveyor or pump panel running 100 cycles/hour translates to over 11 years of service life before mechanical wear-out.
