Product details

Mechanical life of 30 million operations means it handles high-cycle applications.

Key ratings for real motor applications

Coil power draw is steady at 3.3 W both closing and holding, so no intrusive inrush to the 24 V DC supply.

Occupies 45 mm width, 57.5 mm height, 72 mm depth. Side-by-side mounting allowed — no derating gap needed. Main circuit terminals accept 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), max 2x (0.75...4 mm²) or 1x 12 AWG. Same range for auxiliary contacts. IP20 on front and terminals.

Frequently asked questions

What is the depth of 3RT1015-1BB42 on the DIN rail?

72 mm deep, with 45 mm width and 57.5 mm height.

What solid and stranded wire sizes does 3RT1015-1BB42 accept for main terminals?

Main screw terminals accept 2x (0.5…1.5 mm²), 2x (0.75…2.5 mm²), max 2x (0.75…4 mm²) or 1x 12 AWG.

Will 3RT1015-1BB42 drop into a panel designed around 3RT2028-1BB40?

No — the 3RT2028 is a larger frame with different mounting hole pattern and terminal spread. You cannot physically swap them without replacing the entire contactor assembly and retermination.

What compliance documentation is available for 3RT1015-1BB42?

RoHS compliance is indicated with a substance prohibitance date of 2006-07-01. Pollution degree 3 per IEC. Further certs (UL, CSA, CCC) not listed in this datasheet extract.
