TE Connectivity Power Relays, Over 2 Amps 26-57-73

The KISSLING Series 26/300A relay is a dual-coil monostable relay designed for heavy-duty applications in commercial, military, and aviation environments, featuring IP67 and IP69K sealing, 30G shock and 10G vibration resistance, and a continuous current rating of 300A. The 26.57.73 variant includes auxiliary contacts, suppression device, and 24/28VDC coil voltage with a weight of 0.39 kg (0.86 lb). It operates within a temperature range of -55°C to +74°C and meets MIL-R-6106 standards. The mounting configuration allows optional bracket styles with threaded insertions for M8 and M4 fasteners. Contact insulation resistance is 100MΩ initially, with a dielectric strength of 1050VAC for one minute. Maximum contact voltage drop is 150mV, and the relay supports 50,000 electrical cycles at 300A resistive load. Output contact ratings are 2A continuous, 6A make/break. The electrical characteristics and environmental ratings apply uniformly to all Series 26 variants.
