Product details

It carries a characteristic F1 curve and a 2 A rating, breaking up to 3 kA AC under IEC 60934. The F1 characteristic means it handles moderate inrush without nuisance tripping — a middle ground between B and C curves, often specified for control transformers or small motor starters where the start-up surge is higher than a resistive load but not as sharp as a motor direct-on-line. Rated for 230 V AC (50/60 Hz) and 60 V DC, with a maximum DC operating voltage of 72 V and single-phase AC up to 250 V.

Mounting position can be horizontal or vertical. Degree of pollution 2, overvoltage category III — typical for distribution boards and control cabinets in industrial environments. Sealable, halogen-free, silicon-free. The supply cord can enter from any position. Supplementary devices can be installed on the side. Vibration-resistant per IEC 60068-2-6. Mechanical service life is 6 000 operating cycles typical.

Designed and tested to IEC / DIN EN 60934 and UL1077. Halogen-free and silicon-free construction. The manufacturer provides standard compliance documentation (declaration of conformity, RoHS, REACH) upon request.
