Flyer C303 bi-directional DC Contactors

Product catalog summary

Specifications:
The C303 series consists of 1 pole bi-directional DC NO contactors capable of handling up to 1,500 volts and 500 amps. They are designed for high-performance switching with high making and short-time currents up to 5,000 amperes. The contactors are suitable for applications such as battery storage, charging stations, and test benches.

Technical Data:

Max. switching voltage: 1,500 V
Rated insulation voltage: 1,000 V @ PD3 / 1,500 V @ PD2
Rated impulse withstand voltage: 10 kV
Conventional free air thermal current: 350 A or 500 A
Mechanical endurance: 200,000 operations
Operating temperature range: -40 °C to +85 °C
Weight: < 0.5 kg

Design and Assembly:
The contactors feature a solid 1 pole NO contact system with a high-efficiency arc chamber and permanent magnetic blow-out. The main contact system is made of copper with M6 connections.

Coil Control Options:

Ecosave: Energy-saving PWM module for reduced power consumption and heat generation.
High-efficiency drive (HED): Economical drive without PWM module for maximum efficiency.
Precharging contactor: Limits high making currents to protect main contactors.

Safety and Efficiency:

High breaking capacity under full load up to 1.5 megawatts.
Permanent magnetic arc extinguishing ensures no risk of explosion.
Mirror contact for safe feedback of switching status according to IEC 60947-4-1, annex F.

Mounting and Compatibility:
The contactors are compact and designed for high mounting compatibility in industrial applications.
