This enhancement provides precise contact position feedback for safety-critical applications in electric mobility and industrial energy systems. Measuring just 86.5 x 95 x 44 mm and weighing only 530 g, these gas-filled contactors are a reliable, safe, and space-efficient solution for battery disconnect units (BDUs), energy storage systems (ESS), DC fast charging, and uninterruptible power supplies (UPS).
Designed for DC voltages of 1000 V, the HVC27*MC series is available in 300 A, 400 A, and 500 A continuous current versions, with a single-shot capability of up to 900 A at 1000 V in less than 20 ms. The safety component is fully bidirectional with polarity-free main terminals. A hermetically sealed and gas-filled ceramic arc chamber ensures safe disconnection. The normally closed auxiliary contact reliably reports the main contact state, enabling the immediate detection of switching anomalies or failures.
Offered in versions with 12 V or 24 V coil voltage and UL, CE, and UKCA certifications, the contactors are ready for global deployment. Their robust design meets demanding vibration and shock specifications, supporting safe operation in commercial vehicles, industrial machinery, and high-voltage mobility systems. By integrating advanced switching safety in a compact, installer-friendly form, the HVC27*MC helps customers meet growing regulatory and functional safety expectations while optimizing system architecture.
