The Siemens 3RT2015-2KB41 is a SIRIUS coupling contactor in size S00, designed for switching loads in control panels where a 24 VDC coil is specified.
Switching frequency and duty cycle limits
The AC-3e maximum is also 750 ops/h. These limits prevent overheating of the coil and contacts in repetitive cycles. The contactor is not fitted with an auxiliary switch block.
Environmental range and conductor sizing
This covers most indoor industrial enclosures without active cooling. The spring-type terminals require no screwdriver torque — push the stripped wire in and the cage clamps it.
Physical dimensions and clearances
The contactor measures 45 mm wide, 70 mm high, and 73 mm deep. These are minimum air gaps — no metal parts should be closer.
