Product details

The Siemens SIRIUS 3RT1946-4GA07-ZW97 is a terminal block designed as Type E per UL 508, sized S3 for use with a circuit breaker. It provides increased clearances and creepage distances for combination motor controllers, making it a fit for UL-listed panels where Type E coordination is specified.

It is designed for multi-unit packaging of 24 units, so a panel build requiring several blocks should account for the packaging quantity. The Type E designation means it meets UL 508 spacing and creepage requirements for combination motor controllers — critical for UL 508A panel shops.

Frequently asked questions

Does the 3RT1946-4GA07-ZW97 drop into a panel designed for the 3RT1015-1BB42?

Both share the SIRIUS brand and DIN-rail mounting on a 35 mm rail per DIN EN 50022, but the 3RT1946-4GA07-ZW97 is a terminal block (Type E, Size S3) while the 3RT1015-1BB42 is a power contactor (Size S00). They serve different functions; rewiring would be required to replace a contactor with a terminal block.
