Product details

The 3RT1015-2AM21: Main circuit connections use spring-loaded terminals, accepting 2x (0.25 to 2.5 mm²) solid or stranded, or 2x (24 to 14 AWG). This is a tool-less push-in termination — good for panel build speed, but verify the ferrule spec if using stranded on the customer's AML. The auxiliary contact block is a single instantaneous contact (NO or NC, not specified here).

Switching capacity and coordination

For motor switching, the AC-3 rating at 400 V is 5.5 kW (the standard induction-motor duty). The AC-4 rating (plugging/reversing/inching) at 400 V is 6.5 A — significantly lower, as expected for high-stress switching. Auxiliary contact ratings are given for DC switching: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V. For AC auxiliary loads at 230 V, it handles 6 A; at 400 V, 3 A. For fuse coordination, Type 2 coordination requires a gL/gG 20 A fuse; Type 1 coordination allows a 35 A gL/gG fuse.

Pollution degree 3 (conductive pollution, typical for industrial control panels).

Frequently asked questions

What are the key dimensions for panel layout?

Width is 45 mm, height 60 mm, depth 73 mm. It mounts on 35 mm DIN rail per EN 50022, with a 6 mm side gap recommended for heat dissipation when mounting multiple units side-by-side.

What wire sizes does the spring-loaded terminal accept?

The main circuit spring terminals accept 2x (0.25 to 2.5 mm²) solid or stranded, or 2x (24 to 14 AWG). Use ferruled stranded for reliable push-in termination.
