The AC-4 reversing/inching rating is 15.5 A at 400 V. This covers the common motor sizes for small pumps, fans, and conveyors in a 45 mm wide package. The coil draws 5.4 W DC both on pick-up and hold, so the control transformer and DC supply don't need to handle a surge — it's a constant-load coil. That simplifies sizing for a 24 VDC control bus. Front face is IP20 — finger-safe for the panel interior. The terminal area is IP00, meaning the connection points are exposed and require the panel enclosure to provide the overall ingress protection. Type 1 coordination (contactor may need replacement after a fault) allows a 63 A gL/gG fuse. This gives the panel builder a clear choice: smaller fuse for higher uptime, larger fuse for simpler coordination with downstream motor protection.","metaTitle":"Siemens 3RT1025-1BE84 SIRIUS Power Contactor, S0, 10 kW at 5","metaDescription":"Siemens SIRIUS 3RT1025-1BE84 power contactor, size S0. 10 kW at 500 V AC-3, 7.5 kW at 400 V AC-2.

The 3RT1025-1BE84 uses screw terminals like the 3RT1015-1BB42, so the physical fit and terminal type match. The key difference is the coil voltage — verify the 3RT1025-1BE84's coil rating matches your control voltage before swapping."},{"question":"What is the 3RT1025-1BE84's depth?","answer":"The depth is 150 mm.
