TKD503DOD Electromagnetic Contactor The TKD503DOD is an electromagnetic three-pole, normally open contactor with a double-break circuit design. It features a coil specifically engineered for operation in a 27V DC network. The device includes three independent normally open contacts, each rated for 50A. This contactor is designed to switch DC circuits up to 30V and three-phase AC circuits up to 380V. It is primarily used in aviation electrical systems, both onboard and in ground-based radio and electronic equipment. Built for continuous operation, it is capable of functioning reliably in various climatic conditions, including tropical environments. The TKD503DOD has a non-hermetic, encapsulated enclosure for enhanced durability.

Key Technical and Operational Specifications of the TKD503DOD Contactor • Control Circuit Voltage (DC): 27V • Switched DC Voltage Range: 5V – 30V • Switched AC Voltage Range (360-400Hz): 20V – 220V • Switched AC Voltage Range (45-55Hz): 20V – 380V • Switched Current Range: 0.2A – 50A • Design: Open-frame, non-hermetic • Operating Temperature Range: -60°C to +85°C • Dimensions (mm): 133 × 63 × 81 • Weight: 600g This TKD503DOD contactor is engineered for reliable switching of DC and AC circuits across a broad voltage range. Designed to operate in extreme temperature conditions, it is well-suited for aviation, ground-based radio equipment, and industrial applications where durability and performance stability are essential.
