This is the withdrawal coil variant — meaning it's the replaceable coil assembly that pulls out of the contactor frame, not the fixed-wire type. If you're servicing a SIRIUS S10 contactor on a panel and the coil has failed, this is the direct swap part. The coil mounts inside the SIRIUS S10 contactor, which itself fastens via screw fixing to a mounting plate or DIN rail. The contactor's dimensions (145 mm wide, 202 mm deep, 210 mm high) mean the coil swap is done with the contactor in place — no need to pull the entire contactor off the rail. Verify the coil's surge suppressor (varistor design per the S10 contactor spec) is compatible with your control circuit's transient requirements.","metaTitle":"Siemens 3RT5965-5AU31 SIRIUS Magnet Coil, 277 V AC/DC, Size","metaDescription":"Siemens SIRIUS 3RT5965-5AU31 magnet coil for size S10 contactors.

However, the 3RT5965-5AU31 is specifically a withdrawal coil, not a complete contactor — so the 3RT5065-6AU36 is a contactor assembly, not a direct coil substitute.
