Description

The BSB C7 300A high voltage contactor operates at 1000V DC and supports a continuous current of 300 amps. It ensures reliable current switching even in harsh conditions, preventing contact oxidation or contamination during prolonged inactivity. The contactor offers adaptable mounting options and connection configurations to suit diverse packaging requirements. The BSBC7 series 300A DC contactor is designed with a normally open configuration and a low-power coil. Its construction features epoxy resin encapsulation and a sealed, corrosion-resistant casing, making it ideal for explosive or hazardous environments. This design protects the coil and contacts from oxidation and environmental contamination. Additionally, the permanent magnet facilitates high-voltage DC interruption, while the non-polarized contacts accommodate all application polarity needs. Features and Benefits • Compact and lightweight design • Non-polarized contact • Economization (PWM) optional • Epoxy resin encapsulated and sealed construction for operation in explosive or hazardous environments Applications • EV charging station • Energy storage system • Electric Vehicles • Construction machinery • Heavy-duty truck • Telecom power supply • Power control • Pre-charging • Military equipment
