The 63 A rating on the power side means it handles resistive and moderate inductive loads in distribution panels — think lighting banks, heater circuits, or small transformer primaries. The 24 V AC/DC coil simplifies control wiring: one coil supply works whether your PLC output is AC or DC, so no separate coil-voltage conversion is needed on the panel door. At 3 modular width units (53.5 mm wide), it occupies three standard 18 mm DIN-rail slots. The 71 mm depth and 90 mm height fit within a typical 200 mm deep enclosure, but the installation note requires spacers between units for heat dissipation — the 8 W per pole at rated current adds up, so don't pack these tight without the specified air gap. IP20 finger-safe terminals suit enclosed panel mounting; no washdown rating here, so keep it inside the cabinet. ## Mounting & Thermal Management — Spacer Requirement The critical detail: spacers are required between adjacent contactors for heat dissipation. Plan for at least the manufacturer-specified spacing, or derate the current if the panel layout forces tight packing.","metaTitle":"Siemens 5TT5052-2 SENTRON Insta Contactor, 400 V AC, 24 V AC","metaDescription":"Siemens 5TT5052-2 SENTRON Insta contactor, 2 NO + 2 NC, 400 V AC, 24 V AC/DC coil, 63 A, IP20, 8 W per pole.
