Official Mechanical Endurance Parameters of ABB ESB25-22N-06

Mechanical Durability: 1,000,000 operazioni

Reference Supporting Electrical Endurance (Original Manufacturer Data for Same Model)

1. Resistive loads AC-1 / AC-7a (Illuminazione, Riscaldamento)

Normalmente aperto (NO) contatti: 130,000 operazioni

Normalmente chiuso (NC) contatti: 50,000 operazioni

2. Motor loads AC-3 / AC-7b (Tifosi, Pompe dell'acqua)

Normalmente aperto (NO) contatti: 500,000 operazioni

Normalmente chiuso (NC) contatti: 340,000 operazioni

Note supplementari

1. All models in ESB25 series (ESB25-20/02/22/40/04N-01/06/07) share a unified mechanical endurance of 1,000,000 operazioni, unaffected by contact configuration or coil voltage.
2. Mechanical endurance refers to pure mechanical actuation cycles with no load, only coil pull-in and drop-out; electrical endurance means the effective service life of contacts under rated load switching.
3. Ambient operating temperature range: -25℃ ~ +55 ℃. Temperatures exceeding 55℃ will shorten electrical endurance, while mechanical endurance is barely affected by minor temperature fluctuations.
