Product details

The Siemens 3RT1916-1CE00-ZX90 is a SIRIUS surge suppressor — an RC element rated for 240...400 V AC, designed for direct snap-on mounting onto Size S00 contactors. It suppresses voltage spikes across the coil, protecting the contactor's control circuit and extending contact life in inductive switching applications like motor starters and valve controls.

Snap-on mounting onto Size S00 contactors — no tools required. The RC element clips directly onto the coil terminals of the contactor, occupying no additional DIN-rail space. Multi-unit packaging (10 units) suits panel builders stocking spares for a line of S00 contactors.

Frequently asked questions

What replaces the 3RT1916-1CE00-ZX90?

The official successor is the SIRIUS 3RT2 series surge suppressor. The exact order code depends on the voltage rating required; the 3RT2 variant for 240-400 V AC is the direct replacement. It shares the same Size S00 footprint and snap-on mounting, so panel rework is not required.

Will this surge suppressor fit a 3RT1015-1BB42 contactor?

Yes, the 3RT1916-1CE00-ZX90 is designed for Size S00 contactors, which includes the 3RT1015-1BB42. It snaps directly onto the coil terminals of any S00 contactor in the SIRIUS family, so no rewiring or panel modification is needed.
