Product details

Siemens 3RT1456-6PF35 SIRIUS Contactor — Size S6, 96-127 V AC/DC Coil

It accepts stranded power conductors from 25 to 120 mm², and solid/stranded control wiring from 0.5 to 4 mm². Operating time is 80-90 ms on both AC and DC pick-up, with an arcing time of 10-15 ms. The coil holds at 96-127 V; pick-up threshold is 0.8 to 1.1 times rated value.

The contactor accepts up to 4 attachable auxiliary switch blocks, and comes with one built-in auxiliary switch (1 NO + 1 NC configuration).

Auxiliary contact current ratings vary by voltage: 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 6 A at 230 V.

Frequently asked questions

What are the key dimensions of 3RT1456-6PF35?

Height 172 mm, width 140 mm, depth 170 mm. Mounts via screw fixing with a single 9 mm hole.

Will 3RT1456-6PF35 drop into a panel specified for 3RT1055-6QF35?

Not without rewiring — the coil voltage differs (96-127 V AC/DC vs the 3RT1055-6QF35's coil). Mechanical dimensions and mounting are similar as both are Size S6, but the control circuit must be verified.
