The contactor occupies a 45 mm wide footprint, 102 mm tall, 107 mm deep — that's a standard S0 envelope. Spring-type terminals accept solid or stranded wire from 1 to 10 mm², with dual 0.5-2.5 mm² on the auxiliary side. Clearance: 10 mm upwards, downwards, and forwards; 6 mm at the side.
Rated for AC-1 duty at up to 1,000 operations per hour, AC-2 and AC-3 at 750, and AC-4 at 250. The coil draws an inrush peak of 25 A; holding power at 50 Hz is 0.51 VA, at 60 Hz 0.56 VA. Arcing time is 10 ms.
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
The depth is 107 mm, part of the standard S0 contactor envelope.
Solid or stranded wire from 1 to 10 mm² on the main contacts, and 2x (0.5 to 2.5 mm²) on the auxiliary contacts.
Both are S0 frame contactors with the same DIN-rail mounting and similar dimensions, so the panel cutout and rail position are compatible. However, the coil voltage and terminal type differ — the 3RT2027-2NP30-ZX95 uses a 200-280 VAC coil and spring-type terminals, while the 3RT2015-2AP02 uses a different coil voltage and screw terminals. Verify the coil supply and wiring method before substitution.
