Overview
High-voltage direct current (DC) relays, or DC contactors, predominantly feature a ceramic brazing sealed structure, with hydrogen as the primary protective gas, and employ the principle of magnetic arc extinguishing to swiftly address arcing issues, ensuring safe high-voltage disconnection.
These relays are primarily used for switching DC power sources and are extensively applied in various fields, including new energy vehicles, charging stations, 48VDC start-stop systems, photovoltaic power generation, energy storage, and industrial power supplies.
Kemus’s high-voltage DC relays have established project collaborations with globally renowned vehicle and battery manufacturers, positioning them as a core supplier for major new energy vehicle enterprises as well as battery and electric control companies.
Kemus is a leading provider of electrical switchgear and electronic components. Our products include mini breaker, surge protectors, disconnect switches, contactors, relays, and indicators for voltage and fault detection.
Kemus insists on a comprehensive quality assurance system, ensuring our products meet global standards for safety and reliability.
Product Description

KMSHFE82V DC Relay Characteristic Curves
1) The data is for design reference, it shall be verifed as actual for model selection and fuse mating of short-circuit current test.
2) The upper temperature limit of safe operation and function are set for 180°C and 130°C respectively.
3) It is recommended that the upper temperature limit shall not exceed 130°C when long time operation. The relay may also fail, if the safe temperature limit of 180°C is exceeded.
4) Risks of fire and explosion may exist when the working condition beyond the safe circuit curve. in case of similar working condition,the relay shall be replaced in time.
5) The ambient temperature is 85°C for safe operation and function, and for current above 2000A, the temperature is room temperature with cross-sectional area≥60mm².
6) Even if it is below the safety curve when the current≥1500A, the relay is likely to be bonded during current carrying. lf there is a break beyond the specification, fire and explosion may occur.
7) The contact will severely bounce off when the current≥6000A, which may cause the circuit current cannot continue to rise. lf the fuse cannot be fused in time, the relay may explode and the arc may ignite the relay after the explosion.
