Product details
Frequently asked questions
What is the depth of 3RT1015-2KB42-ZX95?
The depth is 73 mm, which fits in standard 100 mm deep enclosures.
What wire sizes does the spring terminal accept?
The spring-loaded terminals accept 2x (0.25 to 2.5 mm²) solid or stranded, or 2x (24 to 14 AWG).
Will 3RT1015-2KB42-ZX95 drop into a panel specified around 3RT1015-1BB42?
Both are S00 frame contactors on 35 mm DIN rail, but verify the coil voltage — the 1BB42 uses a different coil voltage. The 2KB42 runs on 24 V DC. Terminal type also differs: this one has spring terminals; the 1BB42 may use screw terminals. Check your panel wiring before swapping.
Where can I buy 3RT1015-2KB42-ZX95 and get current pricing?
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
