It carries increased clearances and creepage distances to meet the UL spacing requirements for motor branch circuits — not just a generic terminal block. The front face is rated IP20 and finger-safe per IEC 60529, meaning it keeps live parts out of reach when the panel door is open and an operator's hand approaches from the front. No tool needed, no cover to flip — the block itself is the barrier. This terminal block is sized for Size S3 circuit breakers and contactors in the SIRIUS modular system. It snaps onto the same DIN rail as the motor controller components it serves, keeping the wiring plane consistent across the branch. The increased clearances and creepage distances mean it takes up a little more rail space than a standard terminal block — factor that into your fill calculations if you're packing a dense motor control center bucket. Designed as Type E per UL 508, the block is built for the combination motor controller topology where the disconnect, short-circuit protection, and contactor share a common wiring pattern. The finger-safe IP20 front means it passes the touch test without an extra cover.","metaTitle":"Siemens 3RT1946-4GA07-ZX95 SIRIUS Terminal Block Type E UL","metaDescription":"SIRIUS terminal block Type E for UL 508 combination motor controllers.
