The spring-loaded terminals on the main current circuit accept 2x (0.25 to 2.5 mm²) solid or stranded wire, or 2x (24 to 14 AWG). That covers most panel wiring up to the 20 A fuse required for Type 2 coordination — no lug crimping needed. That suits most industrial control rooms and switchgear cubicles without derating, though mounting side-by-side without spacing (allowed per the listing) will raise the local ambient — factor that into the thermal budget. Maximum operating altitude of 2 000 m covers the vast majority of installations; above that, dielectric strength and cooling derate per IEC 60947-1. The SIRIUS platform has a published lifecycle roadmap, so the 3RT1016 family is a safe choice for designs that need to stay supportable through the next decade. Type 2 coordination requires a gL/gG 20 A fuse upstream; Type 1 coordination allows a 35 A fuse. The contactor itself has a mechanical endurance of 30 million operations, so it outlasts most load-side components in cyclic duty.","metaTitle":"Siemens SIRIUS 3RT1016-2HB42-ZX95 Power Contactor, S00, 24 V","metaDescription":"Siemens SIRIUS 3RT1016-2HB42-ZX95 power contactor, size S00, 24 V DC coil, spring-loaded terminals, 4.5 kW at 400 V AC-3.

The key difference is the coil: the -2HB42 is 24 V DC, while the -2AP02 is an AC coil variant.
