# Power Relay, 29 Series **URL**: https://novapart.co/products/K1159283/power-relay-29-series **SKU**: K1159283 **Manufacturer**: TE CONNECTIVITY / PARTNER STOCK **Category**: Switches & Relays || Relays || Power Relays **Price**: €493.6600 **Stock**: 10+ ## Specifications | Parameter | Value | |---|---| | Svhc | No SVHC (27-Jun-2024) | | Product Range | 29 Series | ## Datasheet 📄 [Download PDF](https://novapart.co/datasheet/farnell:4556207/) ## **KISSLING** ## **DUAC POWER RELAYS** ## Series 29 / 2 x 300A - from TE Connectivity (TE) The economical 29 series double pole power relays with 2 x 300A are developed using our competence and expertise gathered over decades of manufacturing to meet demanding operating requirements. This relay features high shock and vibration resistance predominantly from careful design and an optimized magnetic circuit. The sealing technology used in these relays meets both the IP67 and IP6K9K (steam pressure cleaning) protection standard. This relay series is well suited for various applications in severe conditions. ## Features - Sealed housing conforms to IP6K9K - Robust design - Minimized coil current - Variety of configuration options - 6G shock and 4G vibration resistant - Efficient coil (12V and 24V) and magnetic circuit design with switching properties and holding current requirements Other important advantages are low heat generation in the contact area based on low contact voltage drop, a compact design, low holding current, silver alloy contact material and the use of mechanical and high thermal stability insulating compounds. Both the terminals and housing are corrosion resistant. The design of our double pole power relays provides a sealing rate of IP67 and IP6K9K (steam pressure cleaning) in accordance with IEC 60529 and DIN 40050-9. Relays of this series are available in the continuous current ranges of 2 x 300 Amps. ## Applications - Truck - Bus - Ground support vehicles - Construction and agricultural vehicles - Fork lift applications ## Circuits ## NO/NC-Contact ## NO-Contact **==> picture [196 x 60] intentionally omitted <==** **----- Start of picture text -----**
