Product details

Siemens 3RT1025-3AG60 SIRIUS Power Contactor – S0 Frame, Screw Terminals

Auxiliary contact ratings cover the common control voltages: 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V. The coil operates across 0.8...1.1 × rated voltage at 50 Hz and 0.85...1.1 at 60 Hz, with a rated control supply of 100 V at 50 Hz or 100...110 V at 60 Hz.

Mounting and Integration – DIN Rail, Clearance, and Fill Factor

Side-by-side mounting is permitted, with 6 mm clearance needed at the side for heat dissipation. IP20 on the front, IP00 at the terminals — the contactor is meant for enclosed panels, not open washdown zones. Screw terminals accept 2x (0.25...2.5 mm²) solid or stranded, up to 2x 10 mm² maximum. For AWG, that's 2x (16...12) solid or 2x (14...10) stranded, with a single 8 AWG max. Strip and torque per the nameplate — no special tooling needed beyond a standard screwdriver.

Lifecycle and Sourcing – Active Production, Standard Channel

Short-circuit coordination is specified: type 2 requires a 25 A gL/gG fuse; type 1 allows up to 63 A gL/gG. This matters when the contactor sits upstream of a motor starter — the fuse size determines whether the contactor survives a fault or needs replacement.

Frequently asked questions

What is the AC-2 motor rating for 3RT1025-3AG60?

The AC-2 rating at 400 V is 7.5 kW. For AC-4 reversing duty, it carries 15.5 A at 400 V.

What fuse coordination does 3RT1025-3AG60 require?

For type 2 coordination, use a 25 A gL/gG fuse. For type 1, a 63 A gL/gG fuse is the maximum.

Will 3RT1025-3AG60 fit a panel designed for 3RT1023-1AL20?

Both are S0 frame contactors with the same 45 mm width and DIN-rail mounting. The 3RT1025-3AG60 has a higher AC-2 rating (7.5 kW vs the 3RT1023's lower rating), so it's a direct mechanical swap if the coil voltage matches and the panel wiring supports the higher current.

Where can I buy the 3RT1025-3AG60?

The 3RT1025-3AG60 is sourced to order against an RFQ through independent distribution. Current pricing and availability are confirmed at quote time — submit an RFQ for a firm lead time.
