Product details

It is rated for 115 A in AC-3 utilisation category, which is the standard duty for starting and stopping squirrel-cage induction motors under load — so that 115 A figure is the motor current it can switch, not a resistive-heater rating. The coil is wound for 380 V AC. The unit carries an IP2X protection rating on the front face per IEC 60529, meaning it is finger-safe from the front but not sealed against moisture ingress — expect to mount it inside an enclosure with a higher overall IP rating for washdown or outdoor duty.

Environmental and mechanical tolerances

Operates without derating up to 3000 m altitude. Vibration resistance is 2 Gn (5–300 Hz) with the contactor open, 4 Gn when closed; shock resistance is 15 Gn for 11 ms closed, 6 Gn open. These figures matter for applications mounted on machinery or near rotating equipment where mechanical resonance could cause nuisance dropout. The protective treatment is TH per IEC 60068-2-30, which covers damp heat cyclic exposure.

Frequently asked questions

What is the utilisation category and what does it mean for motor starting?

The utilisation category is AC-3, which covers starting and stopping squirrel-cage induction motors under load. The 115 A rating is the motor current it can switch in that duty — not a resistive or general-purpose rating.

What environmental conditions can this starter handle?

Operating temperature range is -40 °C to 70 °C at rated coil voltage. Pollution degree 3 allows for conductive industrial atmospheres. It operates without derating up to 3000 m altitude. Vibration resistance is 2 Gn open / 4 Gn closed; shock resistance is 15 Gn closed / 6 Gn open.

What fire and flammability ratings does it carry?

Fire resistance is 850 °C per IEC 60695-2-1. The enclosure material is rated V1 per UL 94, meaning vertical burn testing limits flaming drip and after-flame time.
