Product details

The Siemens SIRIUS 3RB3036-1WB0-ZW96 is a solid-state overload relay sized S2, rated for 80 A thermal current at both 480 V and 600 V, with a rated insulation voltage of 690 V.

Mounts directly onto a contactor via the contactor-mounting fastening method — no separate DIN-rail bracket needed, which saves one row in the panel. The integrated auxiliary switch provides a normally-open signaling contact for the 'tripped' message.

Lifecycle status is listed as current — this is an active catalog number within the SIRIUS family, not a phase-out or NRND line.
